Please help!! What evidence from living species supports the theory that species descended from other species over time?

Humans have things that we don't use such as an appendix. Monkeys can walk on two feet. Parrots can talk. Humans have spinal problems because our spine isn't made to be vertical. We share alot of things with other animals. Think about the what you share with a dog, pig, or a bat. For instance animals that only eat plants have teeth like we humans do. Animals that only eat plants have long digestive processes like humans do. They also do not have claws, they instead have thinner nails that an peel, and tear fruit, and other plantage.

then that particular organisms become extinct.
