i have bee wondering whether a new evolution is happening in man. you see that the y gene is continously reducing in size. will there be any man on this land around the next 1000yrs? any one answer.
As evolutionary theory becomes more and more popular, the question of evolutionary direction for the human race has become a very hot and debated topic. Here are some links to a few articles discussing this topic:
Scientific American:Is the human race evolving or devolving?
Michael J. Dougherty, assistant director and senior staff biologist at Biological Sciences Curriculum Study in Colorado Springs, CO
BBC News:Human species 'may split in two'
Evolutionary theorist Oliver Curry of the London School of Economics expects a genetic upper class and a dim-witted underclass to emerge.
MSNBC:Human evolution at the crossroads Genetics, cybernetics complicate forecast for species.
Does evolutionary theory allow for circumstances in which "spin-off" human species could develop again?
Some think the rapid rise of genetic modification could be just such a circumstance. Others believe we could blend ourselves with machines in unprecedented ways turning natural-born humans into an endangered species.
Evolution's Arrow The direction of evolution and the future of humanity
This site includes the full text of my book Evolutions Arrow. Originally Evolutions Arrow was available outside Australia only through this website. For over a year now it has also been available internationally in printed form. The printed version has received a rousing reception including a growing number of very positive reviews, and sparked a unique meeting of evolutionary visionaries in the United States in May 2005. A significant number of printed copies of the book have been sold despite the fact that it can be downloaded free from this website (apparently many people still find a printed book more convenient). Evolutions Arrow is helping to promote a significant evolutionary shift in which increasing numbers of individuals are seeing themselves as having a conscious role in the future evolution of life on earth.
