Relate progressing fossil evidence, changing habitats and climates to multiple adaptations and thus lifestyle changes.
My first example is bipedalism but would another one be that sinc the earth got colder intelligence increased which caused humans to learn how to mke tools and fires?

    i'm not sure if the fact that it got colder caused more intelligence but you're off to a good start...keep trying...i would say "since earth got colder, people started to worry and started getting more ideas about how to make themselves feel...well, warm"
