Growing up as a conservative evangelical Christian I had been taught to consider the story of human evolution as spurious to the Word of God. Over the decades I have reconsidered all the arguments for special creation and against evolutionary creation and now deem my earlier education misdirected. That I may now rightly hold to progressive creationism (as opposed to immediate creationism) and consider it "divinely supernatural and special."
That the Creator God of the universe had supernaturally decreed creation's possibility using the operands of randomness and chaos and be ruled by the teleological principle of life as "always tilting towards biologic struggle and survival" regardless of the (toxic) eco-environments this struggle might occur within. As example, oxygen was a deadly toxin to evolutionary life at one time. As such, at all times the equation of "life" will be tilted towards the principles of creative "freedom" within a weak entropic system (which posits ultimate chaos) against a strong entropic system (which posits ultimate determinism) thus allowing for an evolutionary progression whereby the Sovereign Creator may have fellowship of a kind with His creation.
This then is the scientific teleology of evolution by the decree of its Creator God as proceeding from His very being and essence of love. A chaotic system always tilted towards life of some form. To the Christian, this teleology might take its ultimate form in a chaotic cosmic/natural system driving towards biotic enrichment, thriving biotas, and creative imagining. This may also be known as the Christian hope, which is a kind of theological eschatalogy coupled with Jesus' rule (I prefer the idea of divine participation) of love and goodwill with mankind and creation itself. Thus, evoloution's teleology can unfold toward the Christian hope of loving fellowship between, within, without, and everywhere about, all things (what the process theologian might know as panentheism's complex of driving relationships).

Thus, evoloution's teleology can unfold toward the Christian hope of loving fellowship between, within, without, and everywhere about, all things (what the process theologian might know as panentheism's complex of driving relationships).
Once realizing this, I have lately, in recent years, worked towards describing how this progressive evolutionary creation may exist both on a doctrinal level as well as on a scientific one without going beyond the bounds of modern science (excepting, of course, that I write of it from a theologic and not an agnostic, or a/theistic, viewpoint).
And so, in today's posting, I wish to further explore the idea of human evolution through its taxonomical graphs and charts of recent discoveries of the 2.8 million year old homo naledi (star) species. A remarkable discovery found in an ancient graveyard deep underground by a nimble anthropological team of spelunking women who made this phenomenal discovery happen.
Question 1. Why is the chimpanzee closer to the homo genus than the gorilla? And where do orangutans fit in to this zoological chart?
The homo genus has been characterised exclusively as a genus of "bipedal apes" commonly known as "homo erectus" from which the word "humans" derive but differing from the chimpanzee (pan group) which half walks using both legs and all four limbs to travel. The larger family of apes from which humans have descended, such as the gorilla, or orangutan, primarily use all four limbs to travel while occassionally utilizing bi-pedal motion much less of the time than the chimpanzee genus.
Though all come from the superfamily of hominoidea - as can be seen from the taxonomical charts pictured above - as the species continued to evolve it became separated by zoological classifications from tree dwelling apes (gibbons), to partially tree-dwelling apes (orangutans), to ground/tree dwelling apes (gorillas), to ground/tree dwelling semi-bipedal apes (bonobos, chimpanzees), to exclusively ground dwelling bipedal apes (man).
The chart consequently shows how the chimpanzee genus is further removed from the gorilla genus and is more closely linked to the human genus. This is also supported by evolutionary genetic studies. As a result, the common chimpanzee and the bonobo (pygmy or dwarf chimp) of the genus Pan are the closest living evolutionary relatives to humans, sharing a common ancestry with humans from about four to seven million years ago."
At the perspective of a time-scale, this elapsed period of time also evidences the divergence of humans from chimpanzees. More specifically, the final separation of the Homo genus from the Pan genus is approxiamately 2.8 million years old thus showing us of the importance of the recent "Homo Naledi" cave discovery in August of 2015 in South Africa's Star Cave system.
What does this mean theologically?
In evolutionary terms it is pretty plain how human creation evolved from anthropological studies of the ape. And in theological terms, the passages in Genesis provide an ancient (Hebrew) tribal explanation to creation in non-evolutionary terms as this anthropology was unknown then. However, many well-meaning, Christians have attempted to show a 1:1 correlation between Genesis 1 with either progressive or immediate "theistic evolution" which would be an interpretive error both from a cultural standpoint as well as from a scientific one. At this time ancient man, such as the Semetic and Hebraic tribes, had no knowledge of either science or evolution. Moreover, the implication by theologians of insinuating human guidance by divine authorship supra-intending over a culture's era-specific ignorance is also a conjectural error to the surmise of textual formation.
The take away? Rather than getting hung up on a literal reading or correlation of the Genesis creation stories we may be confident that creation derives from a Creator who crafted an unusually complex method of creation by using all the ingredients of evolution to obtain the current results we are biologically familiar with. And that its testimony in Genesis is simply a literary account by the ancients using mythological description to describe this very same event in their own lay terms and knowledge of their day.
What does this mean? That God is neither denied nor mocked. That He is still Creator-Redeemer and shown to be intimately involved with His creation from whatever direction it came. Similarly, the bible is brought back down to reality, it is no longer made a mystical nor irrelevant collection of ancient manuscripts, and that we might rightly "divide / interpret" it more attuned or appropriately to its times and cultures. Which also means that this same Creator-Redeemer God then is active in our societies and cosmos today as much as He was beforetimes. We have lost nothing except our mistaken impulses to defend or mock our Creator. He needs no defense because He is. And any mockery but shows our deep shallowness to the everyday realities about us.
Too, we must now come to understand that evolution is always occurring - both in our present day as well as in the future beyond us. That it is a process which never stops. That underneath life itself is the continuing titanic struggle of biologic life to always exist despite the (toxic) eco-environments now present or occurring in the future.

That underneath life itself is the continuing titanic struggle of biologic life to always exist despite the (toxic) eco-environments now present or occurring in the future.
This is the marvel of God's creation and the cosmic/biologic equation He has set in place so that at any present moment we, as homo sapiens (human beings), might have fellowship with our Creator-Redeemer, or any derivations of ourselves in ages future. But as humans, we cannot assume we are in exclusive communication with our Creator alone. Even the Psalmists and Prophets have written of the mountains and valleys, seas and skies, trees and fields, and all the living things on earth, as having a "form of communication" with its Creator. That it "delights" in His fellowship, "dances," "sings for joy," and "claps its hands" in response to His Almighty voice. Nay, we are not alone in our praise and dependence upon our Creator God who loves His creation and draws us toward Him into divine fellowship with one-and-all.
And though I do not encourage any form of "supernatural mystical communication" with the trees and mountains, birds and bees, still we find in the poetry and essays of human journals the deep realization that all things are connected and in communication with itself and its Creator God. What I might describe as a form of (process) panpsychism; but again, without getting all crazy and mystical about this observation. As we walk creation's fields and meadows, swim its streams and dive below its waters, we sense God's almighty hand of authorship in its templed majesties and shrouded veils of glory. The godfathers of ecology, John Muir, Henry David Thoreau, and Aldo Leopold, each in their own way reveled in this divine communion connecting humanity's existence even to the original American Indians who sensed the same in their animistic Spirit stories of creational connectedness and sacred fellowship.
Conclusion
To read Genesis then is to read it NOT in an evolutionary context but as (i) an ancient composition set within a paleo-creational understanding of a Creator-God named for His creational activity and perceived by the ancient's supernaturally curious wonder of life's many complex spheres of divine / human / creational interactions; (ii) that into creation's holy charters came creational indeterminacy and sentient freewill struggling between goodness and evil, order and disorder, each redefining the other in terms of fellowship and holiness; (iii) an immediate communion and fellowship with the Creator God and what it may mean for creation and mankind; (iv) that within this communion of struggle, of obedience, and willfulness, both creation and humanity came to be pitted against its God, each other, and themselves; (v) which is then described in terms of "life and death, light and darkness" within the hallowed altars of holy communion; (vi) that with death came the promise of God to be not only "Creator" but "Redeemer" - not only to mankind but to His holy creation as well; and finally, (vii) this holy redemption would come by grace and mercy, forgiveness and resurrection. This then is the fuller story of Genesis when read apart from its more popular classical or literal understanding rejecting evolution. It was what the ancients saw then of God's promise and what we need to see now in our dilemma between science, anthropology, and faith.
To this marvel of God's complex creation we may only bow our heads and utter, "Thank you O blessed Redeemer for your promise of life in the midst of death. Praise you for your wisdom and goodness and grace. For the majesty of your name and the councils of your justice when all things will be made new, and good, and holy, once more. Amen."

Hominini
From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Hominini
The Hominini is a tribe of the subfamily Homininae; it comprises three subtribes: Hominina, with its one genus Homo; Australopithecina, comprising several extinct genera (see taxobox); and Panina, with its one genus Pan, the chimpanzees (see the evolutionary tree below).[3][4] Members of the human clade, that is, the Hominini, including Homo and those species of theaustralopithecines that arose after the split from the chimpanzees, are called hominins; cf. Hominidae; terms "hominids" and hominins).
The subtribe Hominina is the "human" branch; that is, it contains the genus Homo exclusively. Researchers proposed the taxon Hominini on the basis that the least similar species of atrichotomy should be separated from the other two. The common chimpanzee and the bonobo of the genus Pan are the closest living evolutionary relatives to humans, sharing a common ancestor with humans about four to seven million years ago.[5] Research by Mary-Claire King in 1973 found 99% identical DNA between human beings and chimpanzees;[6] later research modified that finding to about 94% commonality, with some of the difference occurring in noncoding DNA.[7]
Sahelanthropus tchadensis is an extinct hominid species that lived 7 million years ago, very close to the time of the chimpanzee–human divergence. It is unclear whether or not it may be classed as hominin—that is, whether it rose after the split from the chimpanzees, or not.
A source of confusion in determining the exact age of the Pan–Homo split is evidence of a complex speciation process rather than a clean split between the two lineages. Different chromosomes appear to have split at different times, possibly over as much as a 4-million-year period, indicating a long and drawn out speciation process with large-scale hybridization events between the two emerging lineages as late as 6.3 to 5.4 million years ago according to Patterson et al. (2006).[8] The assumption of late hybridization was in particular based on the similarity of the X chromosome in humans and chimpanzees, suggesting a divergence as late as some 4 million years ago. This conclusion was rejected as unwarranted by Wakeley (2008), who suggested alternative explanations, including selection pressure on the X chromosome in the populations ancestral to the chimpanzee–human last common ancestor (CHLCA).[9]
All the extinct genera listed in the taxobox are ancestral to, or offshoots of, Homo. Few fossil specimens on the Pan side of the split have been found—the first discovery of a fossil chimpanzee was published in 2005;[10] it was from Kenya's East African Rift Valley and dated to between 545 thousand years, radiometric, (kyr) and 284 kyr (via argon–argon dating). However, both Orrorin and Sahelanthropus existed around the time of the split, and so may be ancestral to both Pan and Homo.
In the proposal of Mann and Weiss (1996),[11] the tribe Hominini includes Pan as well as Homo, but within separate subtribes. Homo and (by inference) all bipedal apes are referred to the subtribe Hominina, while Pan is assigned to the subtribe Panina. Wood (2010) discusses the different views of this taxonomy.[12]

Homo Naledi, New Species in Human Lineage, Is Found in South African Cave

Acting on a tip from spelunkers two years ago, scientists in South Africadiscovered what the cavers had only dimly glimpsed through a crack in a limestone wall deep in the Rising Star Cave: lots and lots of old bones.
The remains covered the earthen floor beyond the narrow opening. This was, the scientists concluded, a large, dark chamber for the dead of a previously unidentified species of the early human lineage — Homo naledi.
The new hominin species was announced on Thursday by an international team of more than 60 scientists led by Lee R. Berger, an American paleoanthropologist who is a professor of human evolution studies at the University of the Witwatersrand in Johannesburg. The species name, H. naledi, refers to the cave where the bones lay undisturbed for so long; “naledi” means “star” in the local Sesotho language.
In two papers published this week in the open-access journal eLife, the researchers said that the more than 1,550 fossil elements documenting the discovery constituted the largest sample for any hominin species in a single African site, and one of the largest anywhere in the world. Further, the scientists said, that sample is probably a small fraction of the fossils yet to be recovered from the chamber. So far the team has recovered parts of at least 15 individuals.
“With almost every bone in the body represented multiple times, Homo naledi is already practically the best-known fossil member of our lineage,” Dr. Berger said.
The finding, like so many others in science, was the result of pure luck followed by considerable effort.
Two local cavers, Rick Hunter and Steven Tucker, found the narrow entrance to the chamber, measuring no more than seven and a half inches wide. They were skinny enough to squeeze through, and in the light of their headlamps they saw the bones all around them. When they showed the fossil pictures to Pedro Boshoff, a caver who is also a geologist, he alerted Dr. Berger, who organized an investigation.

"Just getting into the chamber and bringing out samples proved to be a huge challenge.
The narrow opening was the only way in." - Lee Burger

Paul Dirks, a geologist at James Cook University in Australia, who was lead author of the journal paper describing the chamber, said the investigators first had a steep climb up a stone block called the Dragon’s Back and then a drop down to the entrance passage — all of this in the total absence of natural light.
For the two extended investigations of the chamber in 2013 and 2014, Dr. Berger rounded up the international team of scientists and then recruited six excavating scientists through notices on social media. One special requirement: They had to be slender enough to crawl through that crack in the wall.
One of the six, who were all women and were called “underground astronauts,” was Marina Elliott of Simon Fraser University in British Columbia. She said the collection and removal of the fossils involved “some of the most difficult and dangerous conditions ever encountered in the search for human origins.”

Besides introducing a new member of the prehuman family, the discovery suggests that some early hominins intentionally deposited bodies of their dead in a remote and largely inaccessible cave chamber, a behavior previously considered limited to modern humans. Some of the scientists referred to the practice as a ritualized treatment of their dead, but by “ritual” they said they meant a deliberate and repeated practice, not necessarily a kind of religious rite.

“It’s very, very fascinating,” said Ian Tattersall, an authority on human evolution at the American Museum of Natural History in New York, who was not involved in the research.
“No question there’s at least one new species here,” he added, “but there may be debate over the Homo designation, though the species is quite different from anything else we have seen.”
A colleague of Dr. Tattersall’s at the museum, Eric Delson, who is a professor at Lehman College of the City University of New York, was also impressed, saying, “Berger does it again!”
Dr. Delson was referring to Dr. Berger’s previous headline discovery, published in 2010, also involving cave deposits near Johannesburg. He found many fewer fossils that time, but enough to conclude that he was looking at a new species, which he named Australopithecus sediba. Geologists said the individuals lived 1.78 million to 1.95 million years ago, when australopithecines and early species of Homo were contemporaries.

The discovery of a new hominin species is making headlines around the world this week but what many people don't realize is that the excavation team that uncovered this historic find was made up of six daring women scientists! The fossils were found at the bottom of a cave system in South Africa; one of the scientists, Marina Elliott, said that their collection and removal involved "some of the most difficult and dangerous conditions ever encountered in the search for human origins.” Thanks to the dedication of these six women, people everywhere will have the opportunity to gain new insight into the development of our species.
Palaeoanthropologist Lee Berger learned about the fossils in Rising Star Cave in October 2013 -- as well as their location, at the bottom of a 36 foot long shaft that gets as narrow as 7 inches across. He put up an ad on Facebook seeking scientists with a background in archaeology or paleontology, but with a catch: “the person must be skinny and preferably small. They must not be claustrophobic, they must be fit, they should have some caving experience, climbing experience would be a bonus.” He remembers thinking that “maybe there were three or four people in the world who would fit that criteria”, but within days he had 60 qualified applicants from around the world. He narrowed those down to six: Marina Elliott from Canada, Elen Feuerriegel from Australia, and K. Lindsay Eaves, Alia Gurtov, Hannah Morris, and Becca Peixotto from the United States.
Elliott, who was finishing a Ph.D. at Simon Fraser University when she saw the ad, was first on the scene. “I was predisposed to extreme environments,” she says. “Telling me that I’d have to do climbing, that it would be underground, and that it would be strange and potentially dangerous… it appealed.” Even still, she vividly recalls her first sight of the chute: “It’s a long crack, punctuated by shark-teeth protrusions. I remember looking down and thinking: I’m not sure I made the right decision." Given the difficulty and potential danger of the climb, Berger nicknamed the team “underground astronauts.”
During the 21-day excavation of the Rising Star cave, the team had to work carefully: “There was so much material and it was friable and delicate,” Elliott says. “And every day, we realized that we were pulling out another 40 or 60 fragments of this thing that was going to be incredible.” She and her five caving teammates excavated a nearly unheard of collection of hominin fossils: 1,550 fragments from at least 15 skeletons, representing a mix of male and female individuals. In the words of Ed Yong of The Atlantic, “To find one complete skeleton of a new hominin would be hitting the paleoanthropological jackpot. To find 15, and perhaps more, is like nuking the jackpot from orbit.”
Debate about Homo naledi’s age and importance in human prehistory, as well as the intriguing possibility that the bones are in the cave as a form of burial ritual, will be ongoing for years, but no one doubts that it represents an extraordinary find. Elliott has remained on the ground in South Africa where she is now directing the field operation and leading expeditions into other caves, eager to discover what else is out there. As she says, “We’re just scratching the surface."
