A mass extinction.
Extinction, maybe?
extinction
As they live the organisms comprising a species will age and die, they therefore need to reproduce (have babies) in order to replace the members of the species that die or the species will cease to exist (become extinct).
By the theory of evolution, new species form through the process of natural selection. This process most often starts with a random mutation in the genome (a random gene suddenly changes or becomes a "mutation"). This mutation either helps, or hinders the new animal (or mutant if you will hehe). If it helps them survive better than the older species, then this new mutant species will become more abundant. If not, than the new species will die off. This process does not happen all at once though, it usually takes a generous amount of mutations and thousands of years for this to happen.
Metabolism is the slow process of by which living things change. If metabolism stops, everything will die off.
People often think of evolution as what they call survival of the fittest. However, that means a fight among members of a species. This is not what is really meant. The 'fight' is with the environment and the species and not a fight of one individual with another. If the species has a way of best surviving what the environment throws at it, it will survive. Other species might not and will die out.

Sloths can die at any time, just like any other species; all species are mortal.
If all members of a species fail to reproduce, the species will die out and can become extinct.
That is really racist.Answer:There are no fewer than four species of plants by that name, each with different temperature needs.
Because as the forest environment in africa became more grassland like the species that were good at climbing trees died off leaving only those who could see over the tall grass and live in groups and use simple tools
