it suggested that over time the species had evolved and adapted to the climate they were in.
That resources, food growth, expand arithmetically while populations in vrease geometrically (exponentially ), So Darwin thought this was a good observation that could be used in nature. Many more organisms are born than the environment can support, so there is a struggle for existence and the organism best suited to the environment will survive and be mire reproductively successful.
I can think of nothing that (even before it has any existence) predetermines its genetic inheritance and lifetime nurturing environment, and therefore has any responsibility for what it matures to be.
I am sorry but we can't answer because we don't do homework for people nor do we write papers for them. This was not a question as well but a statement. I suggest you write a statement telling the reader the purpose of your paper and what you expect to prove. With that foundation you should be able to write a paper.
some research suggest
The three levels of biological diversity are:Genetic diversitySpecies diversity, andCommunity and ecosystem diversity.
Biogeographic observations indeed suggest that a evolutionary process caused new species to arise, through the process we call natural selection. This is due to an animals adaptability in it's environment.
Biographical observations suggest that a modification process caused new species to arise in the way that new species are showing up without explanation and with new adaptations to their environment. One example that is widely used is the appearance of opposable thumbs in humans and monkeys.
constantly changing
As a species, the brown bear is not endangered. There are many races of this animal, from Asia to North America, and some local populations may be in trouble, I suggest you check the IUCN Redlist, which could give you good info on threatened brown bear populations. Always a good source.
Some species have same number of chromosomes but they are different. suggest an explanation
constantly changing changes often an evironment

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.
It sometimes does but not always. A great deal of evolution by natural selection can happen without the formation of new species. Natural selection is only the process of adaptation within species, and we see many examples of that. Under some circumstances natural selection does play a role in the origin of new species, by which I mean a splitting of one species lineage into two different lineages that do not interbreed with one another - for example, the splitting of one ancestral primate lineage into one that became today's chimpanzee and the other that became the hominid line resulting in our own species. The process of splitting and becoming reproductively isolated, that is, incapable of breeding with one another, can often involve natural selection but perhaps not always.

Physiological similarities suggest the species evolved from the same ancestor.
