The fossil record.
he found out that species who move to different environmental conditions must change their adaptions to the condidtions. by doing that the species must gradually change. this is called evolution.
Biogeography.
The most species are probably in the ocean.
Some frogs, such as the African Reed Frog have been found to change gender, from female to male, when in environments low in male population. There is no evidence currently that the majority of frog species are capable of this change.
On his travels he found that many species of animals were similar, but different even though they were not in the same environment. I suggest you read On the Origin of Species or pick up a good book on Darwin. There are also books specifically about his time on the Beagle.

A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
yes, if new evidence is found
The discipline of biogeography.
Biogeography.
it changes as new evidence is found. it is open to change
The evidence of Coelophysis are multiple fossilized skeletons. Some of them were complete skeletons, which are rare when it comes to dinosaur fossils. There is one known species from the Coelophysis genus.
Where is Physical Evidence found and collected?
There is only one species of platypus, Ornithorhynchus Anatinus. It is found only in Australia, and it is the only species of platypus that has ever been known by Man Fossil evidence indicates that the modern platypus's predecessor was larger, with teeth.
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
Humans and apes had a common ancestor. A mix of human and primitive traits found in the brains, hips, feet and hands of an extinct species identified last year (2013) were found. There is also new evidence that this species had the hands of a toolmaker. Fossils of the extinct hominid are known as Australopithecus sediba.
