the main factor for the increase of diversity is the environment. in many areas of the world the environment changes rapidly, and because of this animals have to adapt quickly, sometimes change in behaviour. so many animals evolve into something new that will benefit them more in that environment, take finches for example (theory of Charles Darwin), many finches evolved to have different beaks to suit the food they were provided with in the area (Galapagos Islands). in some cases animals permanently move from their normal habitat to a new one where the environment is more suitable for them. and that's why there is a diversity in animals.
sexual reproduction
natural selection and adaptive radiation
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
No. It is merely one of many parameters that influence the direction of evolution, and can actually be a driving force in evolution. For example, the rise of warm-blooded mammals as a result of colder climate (a clear period of limited food resources) caused by climatic or astronomical phenomena, like the impact of a meteor.

i dont no It was at the Galapagos Islands where he observed finches andd marine iguanas.

You can believe evolution was caused by God and he controls it.

Changing demographics is an urgent reason for the increased interest in managing diversity in the workplace.

Natural Selection is what Darwin believed was the cause of evolution.
