National Geographic, August 2002: New skull finds.

Dmanisi is a republic named Georgia, It's located in south west Asia between the Black sea and The Caspian Sea. It's located at the same latitude as Italy. 1.75 million Years ago when the Black and Caspian thought to be connected, were part of an ocean. Making this land very lush and livable.

Homo habilis thought to be part of the footsteps out of Africa for man kind (and even possibly racial tensions in today's Middle East). An animal living 2.4 to 1.6 million years ago. Relatively half the body size of a modern man and also brain size to body ratio was about half. I am not sure whether to believe the "brain size to body ratio" theory. Homo Habilis were users of Oldowan tools. Consisting of choppers and cutters limited tool sophistications relatively speaking. Having smaller bodies and longer arms, lower centers of gravity, Homo habilis are guessed to be better suited for arboreal life. Very muscular and strong in characteristics. Homo habilis was a creature mastering diversity. In the shade swinging through the trees and also traveling distances in the sun by foot. Not excellent at one but proficient at both.

Any ways back to point of my yappings. Why dose an animal evolve or change? IT has to survive, either adapt to the environment, current conditions or both or not. I really think our early ancestors were pushed to migrate, I am not really sure why. I think the authors are wrong about brain size, "this skull reopens so many questions about ancestry that one scientist muttered: they ought to put it back in the ground". "Had a tiny brain--not nearly the size scientists thought our ancestors needed to migrate". My thoughts are brain size dose matter, but you can't just assume a small brain, no migration out of Africa that's ludicrous. Possibly they were pushed out of Africa for some reason, possibly it was just luck or even one individual such as (a smart Homo habilis) Einstein Homo habilis led a group out of Africa. Maybe gray matter to brain ratio matters more then Brain size to body ratio. With strong instinctual habits to survive with a body made to travel and be in the trees, maybe they were not that intelligent. But they did make it to the republic of Georgia. Maybe they had the best trait of all the ability to change and adapt to new environments.

My main point, there are more factors that led our ancestors out of Africa. I am not sure which and I may be wrong but I believe its more complex then "brain to body ratio".

But, I am going to guess there was a cultural structure formed among Homo habilis groups. With leaders, brothers, sisters, mothers, fathers, and even between males and females. Interconnected relationships among the group. Possibly migrating for similar purposes as of animals of today, for the bettering of life. In some theories the ability not to adapt to changing environments means death. The abil
