Can the human race continue to evolve?

Question

With all the benefits for the disabled and for those unable to help themselves to keep them alive; can a human with a beneficial mutation out compete all other humans and by natural selection have the mutation become the standard for humans over a long period of time? Can competition for resources in which a human with a mutational benefit is more efficient at still be conducted?

Answer 1

Humans could still evolve but it would take a very large disaster to start it off. The human race has made life too easy for evolution, there is no competition for food, mates or shelter so the weak do not die out and therefore the stronger individuals are not the only ones to pass on their genes. If there was a large disaster which made all or at least most commodities void, then the human race would start to die out, but the strong would survive more.
On a smaller scale, evolution is happening right now in very subtle ways, these changes in humanity are too spread out and sparse for any noticable change to occur but compound change over time would bring noticeable difference.

Answer 2

Well, i think they can. We have evolved to a kine of standard, but we are evolving at a very slow rate. For example:

There was european girl who grew up in Africa from the age of a few months. She had a pet monkey and there were othermonkeys around. She would klimb in trees with them all the time and became very flexable and he feet developed to resemble hands more that other peoples'. This was becaues he body adapted to its environment over the years. This, however is not a true form of evolution, as she was not born that way and i dont believe she could pass it on genetically.

Another examlpe which is more accurate:

these days, many people are born with smaller jaws than earlier humans or even those peoples' earlier ancestors. This is because we use our jaws less and less. The food that earlier humans had to eat was more tough and hard, so we needed quite large jaws with lots of flat back teeth and a few sharper front teeth.

However, now, jaw size is becomming smaller....very slowely....and gradually people have less and less flat back teeth because we dont need them that much any more, due to the "easy to chew" food that we get today.

Answer 3

the nature of life is to modify or stagnate and die off. There are continually random mutations interior the genetic pool. The adaptive transformations have a tendency to persist see you later because the optimal situations for the substitute to stay adaptive persist. Mankind did not evolve from monkeys. Very early in primate evolution the divergence from our common ancestor (people and monkeys) got here about. we are fantastically developed primates. it really is the medical consensus right this moment that our closest primate relative (amino acids/protiens/genes) is the chimpanzee. both significant perspectives on evolution (slow as adverse to puncuated equilibrium) have tended to merge right into a synthesis of both. Puncuated equilibrium means that evolution has a tendency to be static for lengthy era of time, then make an intensive leap causing a clean species to be produced. Sorry about the lengthy answer. the acceptable position to get a extra appropriate answer will be both the wide-spread public library and/or the lecture room. in case you pass to the library get the most up-to-date books they have. you should cruise the internet yet attempt to substantiate the veracity and popularity of the factors.

If a new virus hits the human race it could be that the only survivors would be the ones that have a genetic mutation. Bird flu is mutating, if that found a new way of infecting people and if it had a long time before it showed up then we could all be infected before any one new.

Answer 5

Whilst the human race could evolve it won't. We have decided that how we are now is the pinacle of evolution and as such any mutation that could benefit the species (an extra leg or extra fingers, extar eye, etc.) will be bred out of the population.

Any mutations we see now are removed or altered by surgery and so we will not evolve.

Answer 6

Yes.
The human race is basically still at end of embryo stage in life, compared to people who eat sawdust.
contageous mutations such as people with downs syndrom are all spastics, and therefore should be helped by us, more caring creatures.

Answer 7

To be honest, i don't see any more evolution for the human race.

Todays life style is all about comforsts, and if your life is comfortable why would your body want to evolve?

Evolution usually happens due to a preditor always hunting the race so the species develops armored backs and such and such...

Answer 8

Sure why not?
we are evolving at this very second. in awhile, redheads, will be extinct [with thier fair skin] because of the ozone layer being ruined, the body will not be able to have such light skin. we may have a world of dark skinned people in a few hundred years, or thousand.And who knows what else!

Answer 9

We`ve come to a dead end psychology specking. The encephLon is as big as gets. Technologically, we are excelling. As for disabled, if they compos mentis we should allow too exist, but, if they are in vegetative are we should allow too die.

Answer 10

yes its very possible

in a thousand years the human race will lose the little toe
