What group animals includes modern humans?
Modern humans belong to a group called hominids. Homo sapiens, or humans, are the only surviving species of hominids. Hominids are part of a larger group of animals called primates, which includes monkeys and apes. Humans are also mammals.
What traits did modern humans inherit from australopithecus afarensis?
Modern humans have inherited certain traits from Australopithecus afarensis, such as bipedalism (walking on two legs), similar dental patterns, and the potential for longer childhood development periods. These traits are believed to have played a role in the evolution of hominins leading up to modern humans.
When did humans and mammals appear on earth?
The first true mammals appeared on Earth around 200 million years ago, in the late Triassic period. However, these mammals would remain small and relatively insignificant due to the dominance of the dinosaurs. Only when they died out 65 million years ago did mammals grow and diversify to become the ones we see today. The first modern humans (Homo sapiens sapiens) evolved around 200,000 years ago.

What evidence suggests that humans and bats have a common ancestor?
For one, both humans and bats are in the class Mamalia, which is reason enough to suggest that they come from a common ancestor. The modern classification system, developed by Linnaeus, and modified by scientists such as Darwin and Lyell, is based of common ancestors. So, all mammals come from a common ancestor. How do we know this? Well, all mammals share a peculiar trait: All mammals are completely indistinguishable at the pre embryonic stage. This proves that bats and humans come from common ancestry.
Did modern reptiles evolve from dinosaurs?
No, modern reptiles did not evolve from dinosaurs. Modern reptiles and dinosaurs both belong to the group known as archosaurs, but they evolved along separate lineages. Dinosaurs went extinct around 65 million years ago, while modern reptiles, such as snakes, lizards, and turtles, continued to evolve and diversify.
