Differential Reproductive Success

Some creatures will leave more young, they have an advantage, called height.High creature can achieve higher vegetation, perhaps because of some reason of low vegetation is deleted.Short biological feed is not good, leaving fewer young.This is a differential reproductive success, because the benefits of high will be passed on to the next generation.Short term would not be as close to success;Therefore, "differential reproductive success" differential.

Mass Extinction

More than 99% of all species, lived on the earth have become extinct.The vast majority (95%) died, because they can't successfully for food or other resources.Or they failed to adapt to the local environment changes more than tens or even hundreds of millions of years.

Rest, more dramatic happened.Not long ago, in a relatively short mass extinction events, killing a large number of species.

Understand the five extinction event, each eliminate more than half of all species upon earth.Sometimes in less than one million years.

Speciation

"A species is an actually or potentially interbreeding population that does not interbreed with other such populations when there is opportunity to do so. "
