If man evolved from cro-magnon through neanderthal to **** sapiens...?

Question

why have we not evolved any further? (yahoo wont allow a biological genus name - how stupid is that)

Answer 1

Man's is no longer evolving at a rate seen before. With things such as heath care and agriculture, natural selection has been slowed down. We are still evolving and it can be seen in our immune systems because, some people carry a natural immunity to Ebola and HIV. If the disease were allowed to run it's course without medical intervention people with these natural immunities would become the dominant people.

Answer 2

Mostly because we have things like food surpluses from agriculture and wheel chairs and modern medicine to insure that the less-fit can survive almost as well as the fit. Its still happening (there are some people in Africa who are resistant to HIV and do not die of it even with no treatment) but I'm glad that there are parts of the world that know nothing of powerful selective pressures strong enough to leave noticeable footprints in the gene pool. We will probably start evolving again eventually, but right now most of us are in the equilibrium part of punctuated equilibrium where we are well-adapted for our world (or more accurately can make the world adapt around us). Eventually either we or the natural world will introduce another major selective pressure and we'll change again, but don't hold your breath.

Answer 3

There isn't actually any proof that we haven't. There is the possibility that all those people you hear about who claim psychic powers that most of us dismiss as crazy or hustlers (and no doubt at least some of them are), may actually be the next step of our evolution.

Not to say I believe that, I believe they are in fact crazy or hustlers. But in all fairness, I (and others who think like me), could be mistaken and they may actually be able to see the future or have telekinesis (the ability to move objects with one's mind) or telepathy (the ability to communicate with and/or read another's mind) or whatever else. We may simply be dismissing them too readily because we have closed our mind to the possibility.

There is also the fact that we no longer really have to adjust that much to changing conditions. Up until this point, all creatures have had to adapt to a changing environment that was out of their control. But for the first time in history (assuming evolution is correct), a species has the ability to change the environment (rather than the environment changing them). We have the knowledge and technology to build buildings capable of withstanding natural disasters, or at the very least predict them so that we can run for it.

We have developed the technology to where pretty much we can fight off any predator (not that there are that many, we have destroyed their habitats). We have medicines and technologies that destroy various microbes and diseases before they kill off the weak ones (meaning the weak ones can pro-create along with the strong ones capable of defeating the sickness with just their own immune system).

In essence, we have removed nearly every catalyst to the evolutionary process from our environment (or at least limited its effect drastically). Assuming evolution occurs (I don't believe it does, but I fully understand there being so many who do), we have stopped it in its tracks with technology.

Answer 4

Probably because there are few selection pressures on us. Given the survival rates used to be not much more than 50% and are now close to 100% barring catastrophe I doubt very much humanity will evolve through natural means, now artificial means are a completely seperate question but that would not be natural selection, more like selective breeding.

Answer 5

Cro-Magnons and Neanderthals were cousins...one did not evolve from the other.

Both are considered **** sapiens....Cro-Magnons were identical to the **** sapiens of today.

We are evolving...(read about the FOXP2 gene. In fact, you need to read more science in general)

Answer 6

You realize evolution doesn't happen overnight, right? Changes are, for the most part, tiny and gradual.

And we have removed much of the selection pressure through the use of medical science, so evolution in humans is going to be very, very slow indeed from now on.

Answer 7

Environmental pressures-they aren't very great in modern society hence while man will still adapt and evolve it will be a prolonged process.

Answer 8

We have! Only 100 years ago, the average height for a men was 5 feet. Now it's 6 feet. Also, our bone structure isn't as large as it used to be. We're become leaner and taller. Look it up!

Science is amazing stuff!

Answer 9

maybe we have evolved further. People claim aliens exist. Maybe this is the advanced biological form

Answer 10

Man did not evolve from anything. He was created!! One only has to look at medical science to see the evidence for a creator. Evolution requires that you believe it to be true when there is no evidence!!
