All organisms are adapted to their environment to a greater or lesser extent. If the abiotic and biotic factors within a habitat are capable of supporting a particular species in one geographic area, then one might assume that the same species would be found in a similar habitat in a similar geographic area, e.g. in Africa and South America. This is not the case. Plant and animal species are discontinuously distributed throughout the world
it provides significant inferential evidence foe evolution and common descent, but it also provides what creationists like to deny is possible in evolution
phytogeography and zoogeography respectively.
AnswerZoology is the study of animals and involves research in many aspects of animal life such as behavior, diet, evolution, classification, and distribution.
One long argument with supporting evidence for the theory of evolution by natural selection. Starting with artificial selection, used as an analogue for natural selection, and ending with the distribution of animals, biogeography, Darwin showed the species arose through natural process over long lengths of time.
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.

organic evolution is thus the progressive development of animals and plant from ancestors of different forms and function
\that the animals can be found all around the world fossils

That multi-celled animals exist. Without evolution we'd just be strands of RNA swimming or blowing about.
Evolution of humans and bacteria plus some animals eg)primates.
since darwins time, scientists have confirmed and expanded darwins study of the distribution of plants and animals around the world in a field of study now called biogeography.
* Because it shows that species can change over time
Better features, thus involving better adaptation to the environment, for plants and animals.
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.
The most obvious evidence is that we can observe evolution happening before our very eyes. There are many examples of this, and many experiments have been done and it is shown that beneficial mutations do arise and that organisms do indeed evolve by natural selection.Artificial selection is strong evidence for evolution. Humans acted as selecting agents and forced non random mating in animals, which resulted in a huge diversity of variations. A good example is the different breeds of dogs, all have been artifically selected for their traits. Taking this further, nature can act as a selecting agent through differential survival and produce non random mating.Fossil record is a powerful evidence. The sequence of fossils in the sedimentary layers matches what the evolution theory predicted perfectly. There is not a single out of sequence fossil in the fossil record. Also, there are many fossils that show the entire evolutionary process, for example, the evolution of whales from land dwelling mammals, the evolution of horses, and despite popular misconception, the evolution of humans is well documented by fossils.The geographic distribution of animals is also exactly what we would expect if animals had all evolved from a common ancestor. There are no native mammals in Australia and New Zealand, except for the bat which can fly there, but is unique to marsupial species. Animals on islands differ slightly from the nearest mainland, showing speciation.Molecular data is by far the most powerful evidence for evolution. Our DNA is 98% identical to chimps, which we share the most recent common ancestor with, and it is slightly less identical to gorillas, and even lessly similar to rats, and even lesser compared to fish, and so on. We can make a tree of life using DNA data with their degrees of similarity, and if we take different proteins and compare their DNA independently, they all agree on the same tree.I summarized those evidences from The Greatest Show on Earth -- the evidence for evolution, by Richard Dawkins.
Dinosaur bones, plant fossil, sealife fossil the evidence proves that there were animals long ago, and can support evolution
