Evolution of humans; Cave at Chauvet

"At some point, something happened. Men became wholly and utterly different from every other form of life on the planet--different, as Chesterton writes "in kind and not in degree." When you look at the paintings in Chauvet, again, what thrills you and shocks you is the stark inescapable sense of recognition. They were as human as we."-Different in kind, not degree. How much distance in intellect do you need before you recognize it is in kind!!!-- http://ricochet.com/main-feed/The-Cave-Paintings-at-Chauvet-Or-What-Makes-Men-Men

Evolution of humans; Chromosome 2
by David Turell , Sunday, July 22, 2012, 17:49 (4485 days ago) @ David Turell
We have 23 pairs of chromosomes. The ape primates have 24 pairs. Our chromosome 2 is a fused pair of chromosomes when compared to chimp amd gorilla, indentified by centromeres and telemeres in the wrong places. Perhaps this change is why we are so different from our primate cousins; different in kind, not degree:-http://blogs.discovermagazine.com/loom/2012/07/19/the-mystery-of-the-missing-chromosome-with-a-special-guest-appearance-from-facebook-creationists/-We can only guess as to how important this is at defining the differences between apes and us.

Evolution of humans; brain vs. pelvis
by David Turell , Tuesday, August 28, 2012, 22:45 (4448 days ago) @ David Turell
Which came first, the bigger pelvis or the bigger head? Both had to work together or nothing would have happened. The following article answers little, but offers lots of supposition:-http://blogs.scientificamerican.com/observations/2012/08/28/why-humans-give-birth-to-helpless-babies/?WT_mc_id=SA_DD_20120828
Evolution of humans: Au sediba

More about Au. sediba. A branch or a direct line?-http://www.the-scientist.com/?articles.view/articleNo/35079/title/Human-Ancestors-/-"Despite the anatomical similarities between Au. sediba and Homo, whether the former was an ancestor of modern humans is still up for debate. "Anatomy is very prone to independent evolution," said Richmond. "I think the jury is still out on whether this could have been an ancestor of the Homo genus. . . . There's not enough compelling evidence." But Churchill is convinced. In addition to the features documented in the current papers, the previous Science papers showed Homo-like features in Au. sediba's brain—determined from patterns on the inside of the skull—pelvis, and hand—the latter indicating Au. sediba engaged in Homo-like tool use. "It seems to me much more parsimonious that they share these features with Homo because they are the ancestors of Homo, rather than because they evolved in parallel," Churchill said. There is another possible hiccup to the theory of Au. sediba as the ancestor of Homo, however, said Richmond. "This particular set of fossils"—calculated to be a little less than 2 million years old—"is too recent in time to be the ancestor of Homo. . . . We already have Homo habillis at this time and Homo erectus only a short time later." But Churchill argued that there's no reason why the two species couldn't have coexisted."

Evolution of humans: the bush of human origins

Au. sediba is a hodgepodge of parts and confusing everyone. Huanoid types developed in several directions and the tiny fragments found add to the confusion. All we really know is it started in Africa although primates were developing elsewhere.-"Ultimately, Australopithecus sediba displays a mosaic of features and researchers will need to reconcile this complexity in order to make the case that they have discovered the ancestor of Homo. One of the most important factors to consider is known among evolutionary scholars as homoplasy, or convergent evolution amongst unrelated lineages. If our australopith forebears had each independently adapted to similar evolutionary pressures, the common features in their anatomy would not have been related by descent but by the environmental constraints imposed that resulted in a commonality of form. For this South African clade to be the origin of Homo there would need to be a range of features in common extending from Au. africanus through Au. sediba and ultimately appearing in our Homo ancestors. However, while this mosaic of features may not answer the question of lineage, they do address a more profound mystery."-http://blogs.scientificamerican.com/primate-diaries/2013/04/17/the-mosaic-of-human-origins/?WT_mc_id=SA_DD_20130417

More on Au. sediba:-http://blogs.scientificamerican.com/observations/2013/04/24/is-australopithecus-sediba-the-most-important-human-ancestor-discovery-ever/?WT_mc_id=SA_DD_20130425-"Three years ago researchers added a new branch to the human family tree: Australopithecus sediba, a nearly two-million-year-old relative from South Africa. By all accounts it was a dazzling find—two partial skeletons, an adult female and young male, from a site called Malapa just outside Johannesburg. And it has been making headlines regularly since then whenever scientists release results of new studies of the material, as they did earlier this month. Any time human fossils, especially skeletons, are unearthed it's a big deal, because such remains are so incredibly rare. But I'm going to go out on a limb here and say that A. sediba may just be the most important hominin (modern humans and their extinct relatives) discovery yet."
