History of man?

Question

so if mankind was wiped out how long and would another species evolve to a simialr peak?

also how long has it taken man to evolve from ape etc.?

how much life had to be wiped out for this to happen?

Answer 1

Ive heard that only 1 % of all animals/species/plants etc exist  or are whts left from ...the beginning...

Answer 2

1) Several million years, perhaps much more, if at all.

2) Man did not evolve from apes, but rather from a common    ancestor;  something on the order of 3-4 million years ago?

Just an approximation, from memory.

3) Had to be wiped out?  That's a more philosophical question than "how many WERE wiped out", through man's impact on the environment.  I would say many thousands, if not hundreds of thousands, of species.  This doesn't make us necessarily "bad";  to eliminate our impact on the world we would have to make a point of eradicating ourselves from the planet.  We just might end up doing that, but it wouldn't be intentional.

I think I've read that about 1% of all species that have ever lived on the earth are in existence today; makes sense that we've caused the demised of very many of them.

Answer 3

There's no reason to assume another species would evolve similarly, and much reason to think none would.

Depdending on where you draw the somewhat arbitrary line between not-human and human (we ARE apes, BTW), some millions of years.

??? What do you mean "how much life had to be wiped out for this to happen?" I don't get the question.

There were several mass-extinctions, all of them well before humans.

Go into the Museum of Paleontology, and look at the Earth's History stuff to see about the major epochs and when the mass extinctions ocurred.

Answer 4

some say God created the man and scientific reasons prove otherwise-

to the 1's question the answer to that is mostlikely to be of the same time it took man to get from apes to now isn't it? which was believe it or not 87 million years (we as in our ancestors did live amongst the last of the dinsours however we weren't anything like that of what we are to day.)

Q2 depends on what your meaning for there have been many stages in which the evolutionary phases have taken place that involved i'd say more so blind luck than anything else that set us apart from or more closer other species of homo's LOL

there was a time inwhich we did have more than 1 species of humans on this planet.... i.e. tall..small...smart(us)....strong etc

they all died off due to there inability to cope with there demands of thier enviroment however the small people of some island died off due to mother nature deciding it was there turn to die-volcanic eruption wiped out their source of food.-------------------  man has taken almost  20 million years despite all the gobal cotastrophes such as ice ages and volcanic erruptions to evolve to much of what we are today.

Q3 this seems to be tricky as for the population's would have to suffer great lose and as for what i know this would be to about the number of 10000 less or more not sure like when the earths humaniod populus had been decimated by an apparent, last glacial period and was preceded by 1000 years of the coldest temperatures of the Late Pleistocene. This apparently was caused by the eruption of the Mount Toba volcano. The six-year long volcanic winter and 1000-year-long instant Ice Age that followed Mount Toba's eruption may have decimated Modern Man's entire population.

from this age in the life of man we see diffenate change or evolutionary mark up's in man as for the previous species of man the i.e. Australopithecus's brain size was that of a 3rd of our's today.
