its about evolution?

Question

when was the last evolution of any species,if the has been none since the last are there any species evolving right now,why havent homo sapiens evolved since their last evolution???

Answer 1

Oh, we have, just not physically. Everthing is mental. Universal.

Answer 2

Evolution of species is seen all the time. I think I read something about some insects that evolved into resistance of plastic (previously poisonous to them). Homo sapiens have evolved quite recently to be honest. [1]

Humans will not be evolving much anymore because we are not under strong natural selection as before. We have medicine to keep the weak alive, and we have a population that is too big.

Of course, I am assuming you understand what evolution is, but I have my doubts about assuming correctly. You probably think of evolution as turning from once species to the next. If you don't believe this and understand evolution, please disregard this comment.

Answer 3

Evolutionary processes involve advantages conferred onto certain genetic abnormalities by environmental pressures. Evolution is not an ant turning into a beetle in one generation, but instead one slight change that leads to more offspring, all the while those offspring are separated from other members of the original species. This causes a branching effect, resulting in two distinct species. When complete, these species cease to be able to naturally interbreed in a way that produces offspring that are not sterile. (Witness horses and burros. They produce sterile mules.)

Given this process, it takes many generations to notice. This kind of evolutionary process is being observed in bacteria and viruses, but for larger species, it takes a long time.

The problem with homo sapiens ongoing evolution is that we are no long isolated. We have become both mobile and pervasive, so the chances of a new human species arising is practically nil.

Answer 4

Homo Sapiens are continually evolving. Back in the 1700's, the average height of a man was well under 6 feet - now the average height of the man is several inches taller. Girls are developing faster than they were 50 years ago. There are a ton of examples. I am a Christian, but I do believe in evolution.

Answer 5

Evolution is still going on. We have seen it happening first hand. Humans are evolving, too. We're different than we were thousands of years ago. In a few thousand more years, we may be even more changed.

However, it is true that humans are mixing too much to really split into various groups. That started happening a long time ago, and we can see evidence of that genetic drift in the different races around the world. If humans never came back together, we might have different species of humans in a half million years, or possibly sooner. However, the human race has constantly spread over the world and differences in genetic ultimately get mixed again as one culture conquers another culture. These days, we can go around the world in hours, so that mixing is even greater.

The whole world, now, is one big evironmental niche. So, I think you'll see more homogeny between humans and smaller differences.

Answer 6

We are about 2 feet taller than we were in the 1600's. Go look at an old bed or real knights armor. You won't fit. Our jaws are getting smaller, you probably had your wisdom teeth pulled. Evolution is slow. You can't just watch it, but to claim there aren't measurable changes is absurd.

You would do better with other species. There are some turtles that haven't changed in millions of years. Evolution does not require change for successful species. It only encourages changes that make them more survivable. Cows, goats, dogs, chickens and most other things man keeps have changed quite fast because we help evolution along. Look at cattle in old paintings and you can see they look much different.

Answer 7

Evolution is taking place all the time. Catching the moment of transition is challenging. "Sports", sudden variants are well known in botany.

Animal are more gradual. Homo sapiens, "Modern Man" has been around for about 130,000 years. Homo habilis, the first truly Man-like being was around for 700,000 years. Wait a few hundred thousand years and we'll see how gradual or sudden human evolution is.

Answer 8

A) The finches of the Galapagos Islands are the best known evolutionary examples still.

B) Homo sapiens sapiens HAS evolved, even from 40,000 years ago. In Africa to help shed excess body heat, we got taller, skinnier and much darker. In Asia we lost our epicanthic fold and got our noses flattened to better protect the eyes and lungs against a constant wind. In Europe we got slightly shorter and broader, again to conserve body heat during the recurrent ice ages. Our noses got higher-bridged to better warm incoming air for our lungs. Our skin got progressively lighter to allow more sunshine into our bodies for the production of Vitamin D. All of this is evolution at work, genetic selection altering the flesh to better ensure survival of both the individual and the species.

Answer 9

Most species are still evolving - evolution usually takes thousands if not millions of years - so it could be that in 100,000 years (assuming we haven't blown ourselves up) humans will be taller or shorter, more intelligent, or whatever - we may even evolve so that alcohol doesn't effect us and junk food becomes good for us - because over 100's of generations we may change to suit the life style we live.

Answer 10

Evolution is a very very slow process that can only be noticed over thousands of years. Humans for example have evolved to what we are today- millions of years ago we were like tree swinging monkeys. Everything evolves because change is inevitable, everything has a start and a finish- EVERYTHING!

Answer 11

I sugest you take time to study a little biology. You will see that evolution is a constant process ans that homo sapiens is indeed evolving as we speak. Next time you meet your dentist (if you schyzophrenic religious belief allows you to meet medical profesional) and ask him to tell you about the dentition modification in patients in the last 300 years for example...
