If evolution is true why do we still have basic organisms like amoebas?

Question

if we evolved from monkeys why do we still have monkeys?

Answer 1

Evolution is just one mans idea (Dawin), which at the present still has not truly been proven to be fact. Scientists are still working on the theory now.
By the way Dawin just before he died stated that he no longer believed that his theory could not be proven scientifically, and that he himself did not believe in evolution.
So who can tell if is a factual idea or a very good piece of fiction?

Answer 2

evolution occurs only when there is a niche to be filled and there is a genetic mutation within an existing organism to fulfil that niche (a niche is somewhere that an orgasism is adapted to). Higher organisms have evolved from lower forms like amoebas, but amoebas are still there because they still have a niche to fulfil.

If amoebae became more advanced physically such as becoming generally bigger, it would not be good from an evolutionary point of view as it would just be wasting energy but still have the same reproductive system and so evolution would choose the smaller amoeba because it is better adapted.

Hope that helps!

Answer 3

We didn't evolve from monkeys. We share a common ancestor with monkeys, which is why we're quite similar. More similar than either of us are to amoebas, with whom we share a much, much more distant common ancestor.

Lineages diverge as organisms diversify to occupy different ecological niches. If that niche disappears or is more successfully occupied by a new species, the species that occupies it will become extinct.

Both amoebas and monkeys and humans are still the most fitted organism to occupy the niches they currently occupy, hence they all still exist.

Answer 4

You're thinking of it backwards.

The mechanics of evolution does not dictate that all lower life forms WILL evolve into higher ones. It simply states that all higher life forms DID develope from lower ones.

Evolution simply means that life forms can and do adapt and change as a result of many factors, including environmental. When a change occurs in a member of a species, it doesn't change all of the same species instantaneously. That one organism, if it survives to reproduce, will pass those changes on to another generation. Over time, after enough generations have passed and the changes that were passed on become dramatic enough, that group diferentiates from the original so much that it becomes a new species. The original may still exist, but a new branch has now broken off. This process occurs over and over throughout time, creating that vast variety of species we have today, and new species are still developing all the time.

Answer 5

You're looking at it the wrong way.. As if we are the pinnacle of evolution and everything should aspire to be human. Evolution is not something that is aware, it is a process. Life will happen anywhere there is an opportunity for it to. Amoebas have evolved perfectly to make use of a certain niche. Monkeys also. Humans and monkeys both evolved from a common ancestor to make use of different habitats. You might as well say if monkeys are so perfectly adapted to the jungle, why do we still have humans?

Answer 6

Please, please, let this be the last time I have to correct someone on this. We did not evolve from monkeys, we share a common ancestor to monkeys. We all evolved from a single celled organism. But every species evolves from a common ancestor and they split off and deviate. think of it like a tree. The roots are the first single celled organisms. As you move up the tree the trunk branches out and the branches have many times where they split. At the end of the branches, at the tips, are today's species. Some of them are still single celled organisms and some are very complex species. But the single celled organisms are not the same as the ones at the roots. They are however at the tips of the branches near the bottom of the tree where there aren't as many splits and branches. the species on the top branches, where there are thousands of splits below them, are the complex species.

Answer 7

Older organisms survive unless they are all (everyone of them!) eaten by newer organisms. It would be a daunting task to find every amoeba and eat it. Monkeys still survive because man has not killed them all off (yet!). Mitochondria were at one time independent organisms but now they reside within our own cells and even have their own DNA and means of identification because they are passed down to future generations only by the mother. Our very lives depend on the fact that a predecessor did not perish.

Answer 8

evolution comes out of necessity to survive in a changing environment , if there is no change there is no need to evolve , we may have come from monkeys but the there is they were Moore intelligent than the monkeys of even today , or alternatively see Quatermass and the pit

Answer 9

We didn't evolve from monkeys...

All anthropoids (and we are one, as are monkeys) have a common ancestor, many thousands of years ago. We evolved one way, they went another. Different branches of the same tree.

Answer 10

Because everything works in a cycle, somethings grow and evolve, others breakdown and decay, like life and death. There is always a new start and a new begining. For example even us humans started as a single egg cell.
