New species that arise through mutations and cross-breeding between two species are few and far in between. This is nowhere near the thousands of species that go extinct every year. http://www.best4health.net

Just by feeling that many species are replaced if few go extinct is not a good thought at all. The loss of species is ocuring mainly now because of our own faults particularly loss of habitat. We are changing their food habits. Can you replace TigerIronically, apart from inaccessibility (most islands can only be reached by boat), the big cat is

why mangroves here still survive. Dwindling tiger numbers triggered conservation efforts here in the 1960s. By then, conversion of mangrove

forests into paddy land and hunting and poaching had contributed to degradation, resulting in the disappearance of the leopard, wild water

buffalo, Javan and one-horned rhinos, swamp and hog deer and several plant species.

But the canny Royal Bengal tiger, Panthera tigris tigris, survived. That this massive 500-pound terrestrial beast learnt to swim, walk alone

with great stealth to hunt for fish, crabs, reptiles and humans, its varied diet giving it a distinct advantage over other tiger populations, continues to

amaze ecologists.
We should awaken before it is too late!!!

New species will eventually emerge in order to most efficiently consume whatever part of the carbon cycle they may.

It ususally takes considerable time for a new species to emerge from another species, although the process can be sped up with a greater frequency of births and events that select for certain traits above others.

Before the rise of technology, the rate of extinction was relatively slow if present at all. There were large extinctions that happened as result of natural disasters such as astroids, ect. The rate is now more steady however.
