Humans, having acquired the power of rational thought and the ability to change thyeir environment and living circumstances, can control their own evolution. We are no longer dependent on the usual laws of natural selection, in that we can select or discard traits at will. And now, having mastered the genome, humans don't even have to wait for mutations to launch new traits and characteristics to select.
Future humans will be whatever people decide they are going to be, according to what the species thinks will be useful traits. Future humans will even have the power to subdivide H. sapiens into two or more species, with whatever characteristics are deemed useful or desirable. And, of course, these processes will be subject to the kinds of errors that can so easily arise when the future is not thought out very carefully. Most frightening of all is a future human evolution guided democratically, by the will of a pseudo-majority influenced by the wealth and power of a few, concerned only with instant gratification and short-term goals.
11 Species go extinct every hour. Humans put a great deal of pressure on species, habitat loss, overfishing, water, food, etc.
Dogs no longer evolve through natural selection, dogs evolve through artificial selection because humans decide how to breed them.
If you observe how Humans have evolved over thousands of years, our brains have been getting bigger, and we have been losing body hair.
Humans evolved through natural selection for thousands of years, but that is no longer the case. For example, muscular men were more likely to be better hunters, survive, live, and reproduce. Women with larger breast are best fitted for nursing babies, their breast evolved different that that of men, and these traits survived and reproduced. That is why men are attracted to big breasts, and women to muscular men, we look for the best chances for survival, continue our species.
Nowadays, women and men look for other things that ensure survival of the species, financial stability. Most of the people that secure a good job is because they have education and a good IQ.
1. You asked how humans are going to evolve, I can tell you that humans are going to become smarter (Higher IQ) while dumb people (Low IQ) will not be able to reproduce as much as people of high IQs.
Over the long term, centuries, dumb people (IQ of 80) will not exist.
We will be able to live longer as well, 150-200 years in the next century.
Our skin will be Olive/Brown, the same as our eyes. 2. Brown eyes are dominant over light ones.
1. Do you believe that IQ is heritable? If so this is nonsense. Something dramatic will have to change for this to become even remotely true. Ask yourself this: is wealth, education and social privilege associated with higher IQ and vice versa (in the aggregate)? First, the factors that would prevent a high reproductive rate among the idiots have greatly declined in the 20th century with more egalitarian support structures, health care, etc. Moreover, those on the top of the social heirarchy are being greatly out-bred by those on the bottom. If anything we're becoming progressively dumber.
2. This is already the case and has been forever.

Well that is the homocentric bromide but I am not so sure that it is accurate. One would think that a rational species would be more cognizant of its environment and at the very least would be far more protective of it rather than what we've seen from the effects of our very short existence on this planet. One would also think that having acquired rational thought, humans would not be so hell bent upon its own destruction based upon the most irrational reasons, race, ethnicity, religion or class.
Personally, I question the longevity of the species and the positivistic primacy of humans considering how other species have found ways to exist and thrive in this environment. In the long run, who is smarter some ancient extant bacterium that has existed for millions of years or humans who have existed for .006% of the Earth's existence?
The question is: "Will we engineer ourselves into being something that is not human?"
Suppose we began a gene survey looking for positive human mutations. We could then engineer those mutations into the majority of people and this would spread the advantages thousands of times faster than the normal method.

But, if you read the rest of my post, I pointed out that, although we CAN control our evolution, there no assurance that we will do so wisely or productively, and may very well engineer our own extirpation.
We ARE a rational species and we are NOT cognizant of our environment that we have the rational power to manipulate, so what "one would think" is not a good indicator of reality.
Humans will grow tales that will make em better at sports !
Seems that guys into the sport of fishing already have them.
