Document Summary
Lived in monogomous pairs (based on a set of foot prints found) - this is just a guess as no concrete evidence has been found for this. For the 3 earliest species, there is no concrete connection that explains how they are connected. Missing link: a fossil that will allow us to make a connection to others. Anamensis (4. 5-4 mya: afarensis (4. 3-3 mya, africanus (3-2. 4 mya) - first discovered in the 1920"s (called the mighty, garhi (ca. Small brain size (350cc to 450cc) - compared to body size, this is only about 1/3 of modern human brain size. Brain size compared to body size isn"t changing that much. Increase in body size (1. 0 to 1. 5m) - could be used to explain why brain size is increasing. Live in a mosaic environment which includes both grassland and forests. Maybe their not using their front teeth as tools (because they"ve created tools?) Realistic theory: the type of food being eaten has changed.
