If dinosaurs may have evolved into birds and different animals evolved into other animals, where are the human race headed for in our evolutionary path?
Evolution is caused by a change in an animal’s environment selecting one type of animal instead of another. If it suddenly gets hotter, then animals with long fur will find it hard to keep up with those with short fur, and the ones with short fur will have the most offspring, so that the next generation will have more short furred animals than long furred ones. Humans have learned how to control parts of our environment. We have air conditioning to keep us cool in summer, and heaters to keep us warm in winter, so there is less evolutionary pressure on us. It will take a very large change in the world’s environment to begin evolutionary selection of humans again. If you want to know more about this, try finding a book called “After Man” by Dougal Dixon, which looks at what may happen to evolution and animals if man died out tomorrow.
