The mechanisms of evolution include mutation.
The ultimate source of all genetic variation is mutations. They are permanent, transmissible changes to the genetic material (usually DNA or RNA) of a cell, and can be caused by "copying errors" in the genetic material during cell division and by exposure to radiation, chemicals, or viruses. In multicellular organisms, mutations can be subdivided into germline mutations that occur in the gametes and thus can be passed on to progeny, and somatic mutations that often lead to the malfunction or death of a cell and can cause cancer.
Not all mutations are created equal; simple point mutations (substitutions), which comprise the vast majority of genetic variation, usually can only alter the function or level of expression of existing genes. Gene duplications, which may occur via a number of mechanisms, are believed to be the major mechanism for the introduction of new genes; most genes belong to larger "families" of genes derived from a common ancestral gene (two genes from a species that are in the same family are dubbed "paralogs"). Finally, large chromosomal rearrangements (like the fusion of two chromosomes in the chimp/human common ancestor that produced human chromosome 2) almost invariably result in a speciation event.
Therefore it is not likely that all humans will “mutate” equally or at the same time.

With evolution it would take time but there are many posibillities. For example: The need for opticle lenses (glasses) may stop, or photographic memory would be more common, problems like crooked teeth will probably be non-existent. The human race would have definitly become more intelligent, early caveman lived by instinct and werent too intelligent. Another thing to keep in mind is that in the future the process of evolution may speed up because of the cure for the many diseases out there that keep our bodies too busy to work on adaptation.

Most evolution is boring stuff like improvements to the immune system. Furthermore, mutations are always occurring. You have several new mutations that your parents didn't.

could be a number of things, because there is so much we dont understand about genetic coding. I will hazard a guess that it would be more direct use of our brains. We only use ten to 14 percent of them now. Skin could be another mutation with the climnate changes due to global warming and less ozone.

A simple reading of no less authority than the Bible reveals that highly advanced beings like Jesus, Elijah and Moses exhibited supernatural powers and abilities which the greater masses of today cannot duplicate even thousands of years later ---- could they have appeared long ago to reveal what we are destined to become? To evolve to their spiritual attainment....similar to a butterfly appearing among a colony of caterpillars to also reveal their inevitable destiny...just a thought.

If it exist.... which is a big if... than it would probably be either our pinkies disappearing (it is thought of that they are shrinking) or our third molars (which are also thought of to become less and less developed). We do not need these, so people assume that they are going to go away. Again, this is a big if.

evolution is a theory and just that a theory. i like to wonder if we are evolved from apes then why are there still apes?
evolution is not automatic. no one can predict the future such as this.

its already happening extra fingers on the hand they are being surgically removed before the 2Nd birthday because "they" parents and others don't want the kids laughed at because of "deformities"
I have 2 family members who have had this done.

Our metabolisms will slow down and our appetites will decrease due to our use of machines and less labor intensive jobs.
