Recent genetic discoveries are revealing this is a more accurate analogy for human origins than the "branching tree" model. John Hawks discusses the role of connectivity in human evolution in a clip from the new PBS series First Peoples.
Some Paths to the True Knowledge[*] - "Attention conservation notice: A 5000+ word attempt to provide real ancestors and support for an imaginary ideology I don't actually accept, drawing on fields in which I am in no way an expert. Contains long quotations from even-longer-dead writers, reckless extrapolation from arcane scientific theories, and an unwarranted tone of patiently explaining harsh, basic truths. Altogether, academic in one of the worst senses. Also, spoilers for several of MacLeod's novels, notably but not just The Cassini Division. Written for, and cross-posted to, Crooked Timber's seminar on MacLeod, where I will not be reading the comments."
The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
Élisabeth Daynès and John Gurche (not connected in any way, AFAIK) are among a few paleoartists who specialize in sculpting models of ancient hominin species, such as Sahelanthropus tchadensis (Daynes), Australopithecus boisei (Gurche), Australopithecus africanus (Daynes), Homo floresiensis (Gurche), and charismatic favorite Homo neanderthalensis (Daynes, Gurche).

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it. It all depends how you think it.
"So I called my dad over and about five metres away he started swearing, and I was like 'what did I do wrong?' and he's like, 'nothing, nothing - you found a hominid'."The remarkable remains of two ancient human-like creatures (hominids) have been found in South Africa. Some researchers dispute that the fossils are of an unknown human species, but others say they may help fill a key gap in the fossil record of human evolution. [more inside]

Why is the penis shaped like that? [T]he human penis is actually an impressive “tool” in the truest sense of the word, one manufactured by nature over hundreds of thousands of years of human evolution. You may be surprised to discover just how highly specialized a tool it is. Furthermore, you’d be amazed at what its appearance can tell us about the nature of our sexuality.
Any admixture would have to be driven by male Neanderthals. Two years ago we discussed morphological evidence of nontrivial interbreeding. Since then Neanderthal DNA has been examined for genetic support for this model of human evolution, largely contradicting the belief in Neanderthal contribution to modern humanity. Indeed any contribution from the Neanderthal gene pool to the evolution of modern humans might be very rare and indeed it appears that the best candidate gene thus (MC1R) far likely was a result of convergent evolution.

Lucy, one of the oldest and most complete fossilized hominid skeletons, is hitting the road. Although not without a little controversy. (And that's even before the creationists get wind of the tour!)
As the Pentagon ousts plans to turn insects into cyber war machines you'd be forgiven for asking the question: Where does the real digital end and the faked life begin? Are we simulating life synthetically? or just speeding up an entirely natural process? Technologically engineered life is here to stay. Its not far fetched to speculate that simulacra may become all there is.
The first Transhuman Conference On the Law of Transhuman Persons: Whether or not you believe humans are set to evolve into gods, or AI is destined to achieve self-awareness the idea of the Transhuman is a thought provoking concept. Philosophers have debated the nature of the self, of the human for millennia. Is it time to start drafting new laws to govern all possible sentient beings on this planet? or is it all just a science of fiction? a comfortable humanist illusion?
MoAD is San Francisco's newest museum. The Museum of the African Diaspora is the latest addition to the SOMA neighborhood's expanding cultural riches, and promises to be fascinating (and, as far as I can tell, unique in the world). [more inside]
