How are structural similarities of animals used as evidence for evolution?

The following image they provide from Encyclopedia Brittanica helps detail the physical similarities in the skulls between different species of primates:
As you can see, the construction of these different skulls do vary, but are mostly similar in overall shape, and even demonstrate a gradual change over millions of years. While this evidence doesn't outright prove The Theory of Evolution, it does provide much-needed context to convince those who are too stubborn to accept that we are distant cousins with many of today's primate species (and all life on earth, as it began with one single-celled organism at least 3.7 billion years ago).

∙ 11y agoLook to the bones in your forearm and the bones in the forelegs of your cat and/or dog and by seeing the striking similarity in anatomical structure of all these bones know that you and your animal companions, all mammals, are closely related, taxonomically speaking, and share the common ancestry of all mammals.
More importantly, the morphologies of organisms (skeletal structure, body plan, etc) follow a pattern of nested hierarchies. We recognize homologies because they are closely similar within this pattern.

∙ 11y agoIf two organisms share the same priniciple structure, this is a strong indicator that they share an ancestor which developed that structure, and that this structure is beneficial to surviving.

How does comparative anatomy support then idea that organisms share ancestors?
Comparative anatomy does not prove evolution itself, but is strong evidence because it shows that animals and species do change through periods of time; if evolution were not so, there would be no comparison possible since they would either be exactly the same or they would be different species.
Which evidence for evolution uses impressions of plants and animals pressed into sedimentary rock?
The evidence for evolution that uses impressions of plants and animals into sedimentary rock is the study of fossils. The study of fossils and where they are found is a determining factor about what was going on in a period of history.
How does animal classification prove evolution?
5 prove about the animals
Which form of classification groups animals based on their phylogenetic similarities?
ORDER
What are the effective changes to plants and animals in the ecosystem?
There are changes brought up in animals and plants. It is due to evolution.
Compare morphological and biochemical evidence supporting evolution?
The morphological evidence which is shown in fossils to modern animals supports evolution because some dinosaurs, for instance, had feathers and we can obviously see that trait today in birds. The biochemical evidence, which comes in the form of DNA comparison and amino acid similarities, shows that we related closely to monkeys and pigs, which suggests that we have close ancestors to these animals.
What is paleontological evidence of evolution?
organic evolution is thus the progressive development of animals and plant from ancestors of different forms and function
What fact is the basis for using the fossil record as evidence that evolution has taken place?
fossils show the bone structure of ancient animals. you can see remarkable similarities between them and animals today. For example, the bone structure of many dinosaurs were very similar to that of birds today. For humans we found a bunch of steps on our evolution that is very good evidence of it.
What are the types of evidence that support evolution?
\that the animals can be found all around the world fossils
What is the most accurate evidence for evolution?
That multi-celled animals exist. Without evolution we'd just be strands of RNA swimming or blowing about.
How is anatomy used as evidence for evolution?
Anatomy is a useful tool in gaining evidence for evolution. The most useful thing is to examine homologous structures, ie anatomical similarities between different species. The best example of this is the pentadactyl limb. It is found in humans, dolphins and bats. This shows that at some point in the past there must have been a common ancestor from which these 3 diverse groups of animals evolved.
What evidence support the theoryb of evolition?
Evolution of humans and bacteria plus some animals eg)primates.
Are the molecular formulas for each of the amino acids the same?
No, in fact people used to think that structural homology was proof for evolution but if you look at the chemistry of two animals with the same structural homology they will be way different
Developmental similarities among very different animals can be attributed to?
Evolution causes certain things to appear in different animals when used for the same function. These are called analogous structures.
Why is selective breeding by humans of plants and animals evidence of evolution?
* Because it shows that species can change over time
What is the only evidence you have to support evolution?
Better features, thus involving better adaptation to the environment, for plants and animals.
What is an example of evident?
Dinosaur bones, plant fossil, sealife fossil the evidence proves that there were animals long ago, and can support evolution
