The earliest primate identifiable from the fossil record is believed to be a group of creatures called Plesiadapiforms. These small mammals lived around 65 million years ago and are thought to be ancestral to modern primates.
"what was California's climate like when the earliest people lived there?"
mammals,birds ,insects,primates , and sea creatures
Taxes probably came about as soon as people lived together in large societies. Earliest known taxes were probably in Ancient Egypt.
Humans are primates. Apes, monkeys, chimpanzees, etc. are also primates.Skeletons of primates that lived millions of years ago show that the ancestors of humans have changed from rather short hunched and probably furry primates that lived in groups and used stone tools to Homo erectus to the modern human.The theory is that all primates probably had a common ancestor but due to separation of groups, environmental factors and random genetic mutations, speciation occurred and different groups of primates became increasingly different from each other. Modern primates do not look like their distant ancestors after millions of years and each species of modern primates are different from each other. The great ape is different from lemurs and humans. Humans are unique in having the ability to excavate, document and study the remains of organisms that lived millions of years ago.Just as birds had a common ancestor with dinosaurs as did, perhaps reptiles, humans had a common ancestor with other mammals.
The letter A represents Africa, where it is believed that the earliest humans lived based on archaeological and anthropological evidence.

The climate i guess was probably the season it was at the time. Look at my video on the california trail
The earliest ones still around are stromatolites, but there were lots of earlier life forms.

According to the fossil record, the earliest cells lived about 3.5 billion years ago.
