 Hominids Emerge
You belong to the animal group called hominids. Hominids include not only modern humans, but many other hominid species that have lived on the earth. These species first appeared around eight million years ago.
The hominid species did not all evolve in a single, direct progression. In fact, the hominid “family tree” is actually more like a bush, with many side lineages that have branched off and gone extinct. This branching has produced many different hominid species over time and shows that humans have evolved through the same unpredictable process as every other living thing.
There are a few key trends in hominid evolution that occurred through time.

Leaving the trees and walking on land full time was a big step for hominids that set them apart from other primates.

|
Bigger brains relative to body size meant more sophisticated thinking processes than other mammals.

Remnants of primate body parts that we no longer use remind us of our primate origins.
