Question

By the theory of human evolution, we came from monkey but why it's not happening now???

Answer 1

We don't know if it's happening now or not. It is well known that hundreds of species are becoming extinct, but we do not know if any are evolving, as it is a very lengthy process. Each step in the change is so small, it might take a thousand years before the change would be visible. Some creatures and plants found now, slightly different from others, identified as different species, might be very recently evolved, OR might be in the process of evolving into something that, in a few thousand years, will be something totally different.

The TIME taken in evolution is the most over-looked factor....it happens over millions of years, therefore not visible to any one person in his little 60 or 80 year life span.

Many extinctions are now happening, because man's activities have caused so enormous changes in so short a time, the creatures did not have time to adapt. On top of this some recent extinctions resulted from activities which it is hard to imagine possible adaptations to, such as being hunted with guns from a distance - killing from a distance being unknown in the natural world.

Human evolution is the theory which states that humans developed from primates, or ape-like, ancestors. In 1856, a strange skull was found by some workmen in the Neander Valley in Germany. The odd appearance of the skull led some to believe that it had once belonged to a person who was afflicted with rickets. They did not believe it could have come from an ancestor of modern man. It did, however, form the notion that there could have been creatures that were half-human and half-ape. Ernst Heinrich, a German scientist, claimed that if such a creature were ever found it should be named Pithecanthropus erectus, which means upright apeman.

Even before the discovery of the skull, which is now known as Homo neanderthalensis, people hypothesized that there was some sort of transmutation that took place between species. This, however, was not widely accepted. On November 4, 1859, the view on evolution as a whole changed dramatically. This was the date that Charles Darwin published his work The Origin of Species. With the release of this work, the theory of human evolution became a bit more believable. The theory of natural selection was proposed by Darwin within The Origin of Species. This theory states that the physical traits of an organism are selected for according to the environment it lives in.

Darwin's theory piqued the interest of many scientists who went out in search of evidence which would branch the gap between apes and humans. In 1890, a Dutch physician by the name of Eugene Dubois found a low, apelike skull on the banks of a river in Java. Dubois also discovered a humanlike thigh bone near the skull. He concluded that this creature was the link between apes and humans which Heinrich hypothesized about. Other fossils began to be found which appeared to be transitional.

In 1925, Raymond Dart found a skull which was the first to be classified as Australopithecus. The skull looked apelike in appearance, but had humanlike teeth. Dart discovered the skull in a box of fossilized bones sent to him from Tuang. Mary and Louis Leakey also found a number of Australopithecine fossils. The Leakey's main area of focus was the Olduvai Gorge in Tanzania. Another researcher, Donald Johanson, found similar fossils in the Afar region of Ethiopia. Johanson is credited with finding the fossil skeleton of "Lucy", an Australopithecus afarensis, which shows that ancestors of humans were walking upright at around 3.6 million years ago.

As the amount of finds increased, so did the number of species. Today, the family Hominidae (Bipedal Primates) has grown to include the genus': Ardipithecus, the most apelike hominids. Australopithecus, small-brained gracile hominids with mixed fruit/vegetable diet. Paranthropus, smalled-brained robust hominids with a grassland vegetable diet. Homo, large-brained hominids with an omnivorous diet. These are just brief descriptions of the genus given above. Below are some examples of the genus Australopithecus and Paranthropus that eventually led to the view of the Hominidae family we have today.

A. anemensis

A. afarensis

A. africanus

A. aethiopicus

P. robustus

P. boisei

(A. is an abbreviation for Australopithecus)

(P. is an abbreviation for Paranthropus)

Even though these fossils had both human and ape characteristics, the apelike qualities outnumbered the human ones. Scientists sought to find fossils that were closer to modern man than the Australopithecines. In the early 1960's, Louis Leakey found what he thought was another P. boisei skull, however, the brain case was larger than previous finds. After collaboration with P.V. Tobias and J.R. Napier, he named the skull Homo habilis, which means "handy man". He came up with this name because of the tools found at the site of the skull. Leakey figured that the enlarged brain size made it possible for H. habilis to form tools according to how his/her mind perceived it should look like. Other species of this genus that were found include H. erectus, H. neanderthalensis, and our own species, H. sapiens sapiens.

Some controversy concerning the labeling of H. neanderthalensis as H. sapiens neanderthalensis has arisen in past years, as to whether it should be considered part of the sapiens line. Previously, Neanderthals were considered to have been the transitory form from H. erectus to H. sapiens sapiens. The ideology then shifted to a position that Neanderthals were not a transitory form, but were instead a genetic dead end. Their abrupt disappearance in the fossil record has yielded suggestions that Neanderthals were outcompeted and replaced by anatomically modern human beings. The current viewpoint among many people is that Neanderthals were in fact a separate species and have been labeled by some as H. neanderthalensis, dropping "sapiens" from the name.

Answer 3

We came from primates who resembled modern monkeys. Not too long ago we branched off from the other apes.

What is not happening now? Evolution? It's happening very slowly, so your notion that it is not happening "now" is incorrect.

Answer 4

It is happening now.  You just have to have an attention span that can be measured in something other then nano seconds.

The theory of evolution says nothing about "we came from monkey".

If Christians came from jews....why are there still jews?

Answer 5

I guess there are no opportunities for apes to evolve

into anything else. But if humans keep clearing their

habitats, they could adapt and launch a "goreilla" war

on us.

But, according to natural selection, the apes of today

should be "fitter" and more "reproductive" in relative

and absolute terms with the apes of the past.

Unfortunately, there is no real evidence for this.

Answer 6

"Human" is not a goal of evolution.  In fact, it's not even a goal to be more intelligent. Evolution does not have goals.  It simply results in animals adapting to current environmental challenges (or not and going extinct).  

Evolution does NOT happen to individuals.  It happens to populations over many generations.  

Modern animals do NOT evolve into other modern animals.  Goldfish do not evolve into bullfrogs.  Humans do not evolve into gorillas.  Donkeys do not evolve into zebras.  It does not work that way.

If increasing intelligence is a key to the survival of say, chimpanzees and over many thousands of generations they develop their own advanced civilizations, they still would not be human and never would be.  They would be something entirely new.  Humans evolved from an ancient ape-like ancestor that does not exist today.  That evolution happened once and resulted in our family branch of the primate tree.  We were not the only resulting hominid, however.  We had many close human-like relatives.  None of them survived into modern times.  Eventually humans (assuming we don't end up extinct) may evolve into something that can no longer be classified as human, but it won't be an instant jump.  It will be the result of genetic changes over thousands of generations.  Also, it will only come about if we live in an environment that favors new changes.  There is no way to predict the shapes of the future.

Answer 7

This process happens over a long period of time in respose to environmental stimuli.  We are still evolving, it's just hard to see as it happens.  Kind of like when you see a small child everyday it doesn't seem like the change much, however people who son't see them often comment on how much they have grown and how big they are getting.  The species we evolved from are no longer around.  We didn't evolve from modern day monkeys but we do share a common ancestor.  However, if you go back far enough we also shar a common ancestor with your house cat, a tiger shark and an ameoba.

Answer 8

Its a good question, According to theory of human evolution, we came from monkey.  As u told  it's not happening now mean the monkeys are not becoming humans.

the evolution is a gradual and slow process. it happened about 2 millions years ago. and now generation after generation we r seeing the evolution in physical , mental and persnality. even the evolutions are recognising,  but its not a sudden,

only mutations will makes the sudden change in organism that also leads to evolution,

there from the monkeys would not becoming humans now.

Answer 9

Because no scientist ... ever ... has said that humans came from any kind of monkey species *ALIVE TODAY*.

That is an important piece of understanding that too many people fail to understand with their somewhat cartoonlike understanding of what the theory of evolution says.

So ....

First, no monkey or ape species *ALIVE TODAY* would be evolving into humans.    Chimps (our nearest relative, and which is an ape, not a monkey) are no more likely to evolve into humans than they are likely to evolve into gorillas or orangutans, or humans are likely to evolve into chimps.  No monkey species is any more likely to evolve into humans than they are likely to evolve into a different monkey species, or humans are likely to evolve into them.

In short, no *existing species* will ever evolve into another *existing species* ... period.  Ever.   It can't happen.  That would completely *VIOLATE* the theory of evolution!

Second, evolution is SLOW.   So whatever these different monkey or ape species are evolving into, this is indeed happening NOW ... but not at a pace that we would notice over the course of even many thousands of years.   That's a bit like looking at an acorn in your hand and asking "if oak trees come from acorns, they why isn't this acorn becoming an oak tree now???"
