Three changes are probably global temperature change(Ice Age,NOW), and...nothing else. This is most likely the only environmental change that affects evolution.
They thought the evolution of new species is linked to environmental changes
Changes that are genetic
Darwin considered evolution to be caused due to : 1)small changes/variations that occured 2)these variations were directed specifically towards adapting to the environment(directional) 3)evolution was a slow process De Vries believed that evolution occured by: 1)large changes that occured 2)these changes were mutations and were stochastic or random, not directional 3)evolution occured in fits and starts and was not a slow ongoing process
Burning, rusting, and production of gas are examples of chemical changes.
responsiveness
Through evolution, loss of natural habitat and environmental changes.
