What is Microevolution ?
Darwinian theory tells us how a certain amount of diversity in life forms can develop once we have various types of complex living organisms already in existence. If a small population of birds happens to migrate to an isolated island, for example, a combination of inbreeding, mutation, and natural selection may cause this isolated population to develop different characteristics from those possessed by the ancestral population on the mainland. This is Microevolution. When the theory is understood in this limited sense, Darwinian evolution is uncontroversial, and has no important philosophical or theological implications. This answer is adapted from a lecture by Prof.
