Environmental factors don't just contribute - they are the cause of the evolution of a species.
For example, the horse is descended from a dog-sized creature called the Eohippus, which had separate toes instead of hooves, etc.
It's evolution towards the horse came about through an environmental change of some sort. Presumably, the more jungle-like terrain the Eohippus would have thrived in began to thin out, becoming more open plains.
Without trees or bushes to hide in, the Eohippus would have been easier to prey on. The ability to outrun predators would have been favoured by natural selection over the ability to hide from them. As a result, the individual toes gradually became the hooves adapted to running very quickly that we can see today. The small organism would have evolved towards the powerful modern horse.
But without that environmental change, the Eohippus would still be here today.

Charles Darwin used his concept of density dependent factors in his theory of evolution by formulating a scientific argument by use of natural selection. His demonstrations showed how natural selection is the only possible link between adaptation and evolution.
Environmental factors ARE evolution by natural selection. The immediate environment is the selector of the organisms that are differentially successful against the immediate environment.

Factors that arise from a location.
Mainly natural selection, but drift, flow and endosymbiosis are all factors too, just to name a few.
