Genetic differences
Mutation is the cause of evolution. Mutation is what creates differences in individuals within a species, leading to diversion. Then "survival of the fittest" can occur.
The modern concept of genetics was unknown during Darwin's lifetime, and for many years after. Darwin based his theory of evolution upon observation of the similarities and differences between closely related species, and how they could have developed.

The difference is one of scale and scope. This is best explained using a single species and its descendants as an example:Every change that happens to the species up to the point of speciation would be classified as "micro-evolution". But after speciation, divergence would not stop: the two new species would continue to diverge from one another, possibly resulting in yet more branching events, more new species. The scope would increase to include all of those as well. At this scale, we're talking about "macro-evolution". When we zoom in on one of those newly emerged species, we can see that the resulting "macro-evolution" is still being generated by the cumulative effects of "micro-evolution" within each individual population.
They thought the evolution of new species is linked to environmental changes

no the theory of evolution is a species becoming more advanced not over populated
divergence / divergent evolution
Prior to sailing on the Beagle, Darwin was yet to observe different species of animals and plants in different regions. The observations were valuable in conceptualizing evolution. Before the voyage, Darwin believed that species were confined to different geographical locations, but ideas of species adaptation and evolution were nonexistent.
Charles Darwin is known for his studies aboard the HMS Beagle. He went all around the world to study different species and formed the theory of evolution.
Charles Darwin's wrote two books the first was called Charles Darwin's theory of evolution and the second was Charles Darwin's the origin of mammal
