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 random factors, speciation begins. They climbed
more and lived in the trees.
Brain size: from 3 - 1mya there was a
flat line when looking at
Development in children: modern apes
are shorter than modern humans.
Australopiths had a longer childhood, as
this was the trend for primates evolving
into modern humans.
Timing: later Australopiths and early
Homo overlap for more than a million
years, including Homo erectus, so they
might have interbred.
