Evolution; 30years, lizards engage in fast evolution.

[Cyrene]

30 years ago some WHACKED out scientists took a population of lizards and put them onto a new island, a team of international researchers dropped by and inspected the current lizards.

Anyway new lizards have bigger heads, and some kinds of sacs in their digestive track to help digest cellulouse working with some sort of bactiera, the juviniles, young adults and adults all had the new adaptations (proto organ in the works after only 30 years) and adaptations for the new lifestyle in the region. The previous lizazrd popuilation do not have the sacks, almost no lizards or reptiles do. (whichever the article is about)

Link forthcoming if anyone’s interested?

54 years ago some wacked out scientists were detonating hydrogen bombs in the pacific ocean…

Cool!

“Striking differences in head size and shape, increased bite strength and the development of new structures in the lizard’s digestive tracts were noted after only 36 years, which is an extremely short time scale,” says Duncan Irschick, a professor of biology at the University of Massachusetts Amherst. “These physical changes have occurred side-by-side with dramatic changes in population density and social structure.”

Ever couple of weeks or so, New Scientist posts stuff on how quickly natural selection pushes organisms to change. I’ll keep my eye out for some of those articles.I’ll try to keep this link alive with that…

If only humans could evolve so qickly…

[hermes_the_thrice_gr (hermes the thrice great)]

What makes you think they haven’t?

[Cyrene]

Humans evolve very quickly, though not that quickly.

Look at how new the adaptation to digest lactose efficiently and etc is. Its so new that large portions of the world, most people, don’t have it.

genes associated with intelligence have also shown rapid, rapid dispersal across populations, though again, not everyone has them.

Same goes for wheat - many people have an intolerance to it, as it was the last grain to be cultivated: so 1 in 100 people are intolerant to it/lack the adaptation to digest it… I do!
