Comparative embroyology allows us to see the similarities between embryo's of related species. Therefore, similarities between two organism's in the embryo signal that at some point, those two organism's were related. The earlier those similarities disappear, the farther apart evolutionarily the two organisms are.
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.

Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.

Charles Darwin, the creator of the theory of natural selection, was born 1809.
Because there is a large body of evidence to support it.
Life has a great potential for creating diversity.
It is not a matter of agreement, it is a matter of accepting the overwhelming evidences in support of the theory of evolution by natural selection.
The branches of genetics, paleontology, observed natural selection and speciation all support evolution. Examples: (Genetics) Human chromosome 2 resulted from a fusion of two ancestral chromosomes. (Paleontology) Evolution of the horse. (Natural selection) Observed in Peppered moths. (Speciation) The Hawthorn Fly
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
supports hypothesis that species have changed over time.
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
Because in the wild there is a struggle for existence as more organisms are born than there are resources to support them. Thus, there is a wide variety of traits expressed by these many organisms and some of these traits confer survival and reproductive advantages which is what natural selection is selecting for.
Virtually all data and observations in the natural sciences support the idea of evolution through natural selection. There is no hard factual evidence at all to support creationism, which is a thinly disguised attempt to portray the Biblical idea of Genesis as actual fact. Man did NOT walk side by side with dinosaurs, and the earth was not created 4,000 years ago. Creationism is a RELIGIOUS thought, with no basis in fact.
