Question

The cheetah is the fastest land-dwelling animal on the planet. It has been known to reach peak speeds of almost 80 miles per hour! It uses this speed to catch animals that are too fast to be killed by most other predators. According to Charles Darwin's ideas, the cheetah did not allways exist. Instead, it arose from slower predators. How did natural selection produce such a creature?

Answer 1

Faster varieties of cheetah-like cats were able to successfully catch animals and exploit niches better than any competitors. They had more kids. The fastest and most cheetah-like of their kids had more kids than the others. The fastest and more cheetah-like of _their_ kids had more kids than the others. And so on. Over some period of time these cheetah-like cats became recognizably cheetahs as we would know them. Very speciaalized and very good at their particular style of hunting, and thus very likely to become extinct if anything changed in their lives...
