Hi TP, believe it or not, I studied Dart and how he darted (pun intended) between Oz and SA when I researched your question. The fact that I quoted I am not going defend now or ever again - it is not my IP to regurgitate as if it is my own. In fact, I once again stress the importance of ownership of intellectual property.
However, let me get on with it... Dart is best known for his discovery in 1924 of a fossil (first ever found) of Australopithecus africanus (extinct hominid closely related to humans) at Taung in Northwestern South Africa. Since then, like you rightly stated, there has been vindicaton and disagreement of his theory.
As a Christian, I believe in God's creation, including sinful humans.
The majority of anatomical, archaeological and genetic evidence gives credence to the view that fully modern humans are a relatively recent evolutionary phenomenon.
The current best explanation for the beginning of modern humans is the Out of Africa Model that postulates a single, African origin for Homo sapiens. The major neurological and cultural innovations that characterized the appearance of fully modern humans has proven to be remarkably successful, culminating in our dominance of the planet at the expense of all earlier hominid populations.
However, if I interpret your Q's correctly, the following anatomical characteristics have developed, although, as you stated, TP, there is a time lag between the appearance of anatomical modernity and perceived behavioral modernity:
* Neural basis of vocalisation/suggestions - Linguistic superfamilies show remarkable correspondence with the two major clusters, indicating considerable parallelism between genetic and linguistic evolution. The latest step in language development may have been an important factor determining the rapid expansion that followed the appearance of modern humans and the demise of Neanderthals.
* Attention span
* Mitochondrial DNA
* Facial attractiveness iro skin texture and colour
* Sexual selection
* Tool use
* Shorter arms, longer legs
* Less hair
* Problem solving skills
* Y chromosome sequence variance
* Brain size (ASPM)
* Smaller skull size
* Imitative learning
* Insertion of Alu element on the Y chromosome
* Human pheremones
* Femur, tibia, pelvic and pelvis differences
* and in fact, the list goes on and on and on...
