Are there endangered species due to natural selection?

Further genetic differences caused by mutations in the genome causes the original species to split into two species after many generations have passed. Read more here for examples! Evolution by natural selection can prevent extinction. Read more here. read more

There are, however many examples of species dying out because of relatively sudden environmental changes. During the end of the Permian era, close to 95% of all living species did not survive the environmental changes. This mass extinction was much larger than the one that finished off the dinosaurs millions of years later. read more

Natural selection cannot explain the abundance of species we currently see on our planet if all these species stemmed from a single ancestor. The variation that Darwin observed in the finches and other organisms on his voyage with the Beagle led to the concept of evolution by natural selection. read more
