odd....I distinctly smell sarcasm.....
do you sit around today and watch for new species evolving in your backyard?......
If you look at a house built in say, 1750, you'll see that the doorways and rooms... are all smaller than we build them today. that's because over time, humans have been getting taller. That's evolution. And we've already evolved into different "species" of humans, such as asians, blacks, caucasians...
holy crap......are you still playing that tune?......didn't you get embarrassed enough the first time around?........humans have not "evolved" since 1750, they have gotten better nutrition and medical care.......and if you think blacks and whites are different species I hear there's a job opening up for slave overseer that you are imminently qualified for......
Top 10 Signs Of Evolution In Modern Man
Jamie Frater January 5, 2009
Through history, as natural selection played its part in the development of modern man, many of the useful functions and parts of the human body become unnecessary. What is most fascinating is that many of these parts of the body still remain in some form so we can see the progress of evolution. This list covers the ten most significant evolutionary changes that have taken place leaving signs behind them.
Goose Bumps
Humans get goose bumps when they are cold, frightened, angry, or in awe. Many other creatures get goose bumps for the same reason, for example this is why a cat or dogs hair stands on end and the cause behind a porcupines quills raising. In cold situations, the rising hair traps air between the hairs and skin, creating insulation and warmth. In response to fear, goose bumps make an animal appear larger hopefully scaring away the enemy. Humans no longer benefit from goose bumps and they are simply left over from our past when we were not clothed and needed to scare our own natural enemies. Natural selection removed the thick hair but left behind the mechanism for controlling it.
Jacobsons Organ
Vomeronasal organ
Jacobsons organ is a fascinating part of animal anatomy and it tells us a lot about our own sexual history. The organ is in the nose and it is a special smell organ which detects pheromones (the chemical that triggers sexual desire, alarm, or information about food trails). It is this organ that allows some animals to track others for sex and to know of potential dangers. Humans are born with the Jacobsons organ, but in early development its abilities dwindle to a point that it is useless. Once upon a time, humans would have used this organ to locate mates when communication was not possible. Singles evenings, chat rooms, and bars have now taken its place in the process of human mate-seeking.

Junk DNA
While many of the hangovers from our devolved past are visible or physical, this is not true for all. Humans have structures in their genetic make-up that were once used to produces enzymes to process vitamin C (it is called L-gulonolactone oxidase). Most other animals have this functioning DNA but at some point in our history, a mutation disabled the gene whilst leaving behind its remnants as junk DNA. This particular junk DNA indicates a common ancestry with other species on earth, so it is particularly interesting.
