The comparisons between the anatomies of various organisms show common ancestry which supports evolution.

Comparative anatomy and evolutionary development have shown the connection between species; both the near and far connections. Look at the bones in your arm and then at the foreleg bones of your cat or dog and see how evolutionarily close the both of you are. The HOX genes between you and fruit flies, the control genes for making bodies, show that you and flies share common ancestry as suggested by evolution.
Inference (deduction) is the process of determining a conclusion based on given evidence. Since we often can't know precisely what a prehistoric animal or plant looked like (unless it was completely preserved, as is the case with ice or amber), we have to take what bones, casts, molds, etc. that exist, and infer something about the plant or animal based on the structure and surroundings. For example, based on what we know about structure and function of various anatomies of existing animals, we can infer things about dinosaurs based on the bone structures found in their fossils. We can also determine whether they were predators or prey, whether they hunted or traveled in herds, in what class of animal we can group them, and so forth.
Cuvier believed there was no evidence for the evolution of organic forms but there was evidence for succeeding creations after the catastrophic extinction events. But in the course of history, he said, catastrophic events had killed off all members of some species, and their fossils would no longer be seen in the rocks. Later, he believed the old species were replaced by new ones that repopulated Earth. Like many other scientists of his day, Cuvier spoke about the theory of catastrophism. This theory was based on the statement that there have been violent and sudden natural catastrophes such as great floods and other very sudden physical changes to the earth. Organisms that were living in those areas where these sudden, violent changes had occurred were often killed and replaced by new life forms moving in from other geographic areas. The fossil record of this type of area would show rapid changes in species.
== == Homologous provide evidence for evolution because it shows the similarities and how we evolved from the same ancestors
The bones in the forelegs of your dog or cat are homologous structures to the bones that are in your arms. This show the common ancestry of mammals, recently, and all tetrapods ultimately.
They show similarities between organisms structure. if the similarities are large then it shows that those organisms share a common ancestor.
The presence of homologous structures (for example, the bone structure in chimpanzee arms, human arms, and whale flippers) indicates that the species sharing that homologous structure share a common ancestor.
homologous structures- same structure/different functions in common ancestors analogous structures-same functions/differnt structures not in common ancestors vestigial-show evolutionary history/structures that arent used anymore (i.e. human appendix/human tailbone)
Morphological divergence refers to how different species evolve distinct physical characteristics over time. Homologous structures are similar traits found in different species due to a common ancestor. In essence, morphological divergence can lead to differences in body structures, while homologous structures show similarities in body parts across species.
The panda's thumb does not show evidence of design, good or bad. It shows evidence of evolution.
Fossils can be used as evidence for evolution because they can show the development of a species over a long period of time.
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
When comparing earlier and later developments, homologous structures become more refined through time. When comparing common ancestors, we can compare the derivations of a homologous structure between two successors and also between the ancestor and each successor. We thus see several relationships between this and that, from 'right now', 'a little before now' and 'way back then'. For example, we see two species whose legs are very similarly structured, and then we find an ancestor that also possessed such a leg, except it was simpler or shorter or in a different ratio between sections. We can draw conclusions that the later species developed both from this earlier one, and that this earlier one died out, after its successors (which eventually became the newer species) could survive more often because they had better structured legs.
Fossils show the past history, bacteria and viruses show that it's still active.
it shows the process by evolution and study of structures of animals
