Do environmental factors influence natural selection?

Answer 1

Natural selection is a direct product of the environment.

A couple of simple examples are:

In a cold environment the only plants and animals that will survive will be cold tolerant plants and animals.

In a forest of Bears the only animals to survive will be animals that are faster or bigger than Bears.

A sudden change in environmental conditions, such as an Ice Age, will see whole populations of some species disappear while only remnants of some species will survive.

Those remnants will display either cold tolerance or the ability to withstand the cold by other means ie: clothing or fire.

Answer 3

Natural selection affects populations of organisms. More specifically, it affects the way organisms interact with one another and with their environment. And through this, it indirectly affects the environment.

Answer 4

When organisms adapt to a changing environment, genetic variation (a part of natural selection) can lead to diversity.

Answer 5

Yes environmental factors do influence natural selection.
