Document Summary
February 25, 2013: early hominins, australopiths and early homo. Page 228-229: diversity of species/ adaptive radiation: have grassile, aferensis, robust and some homo species all living at the same time in the same types of environments. There are so many species because the groups weren"t travelling far, thus interbreeding in small population. This causes genetic drift, and based on speciation begins. They climbed more trees. random factors, and lived in the: brain size: from 3 - 1mya there was a looking at encephalization, development in children: modern apes flat line when are shorter than modern humans. Africa (mostly east, some in the south: biological remains, greater encephalization, altered cranial shape (higher forehead, arched jaw, smaller and narrower teeth), early homo culture, the first group which had culture, types of tools and nature of behaviour.
