Evolution tied to Earth movement
Scientists long have focused on how climate and vegetation allowed human ancestors to evolve in Africa. Now, University of Utah geologists are calling renewed attention to the idea that ground movements formed mountains and valleys, creating environments that favored the emergence of humanity.

Evolution with a restricted number of genes
The development of higher forms of life would appear to have been influenced by RNA polymerase II. This enzyme transcribes the information coded by genes from DNA into messenger-RNA (mRNA), which in turn is the basis for the production of proteins. RNA polymerase II is highly conserved through evolution, with many of its structural characteristics being conserved between bacteria and humans.

Human evolution speeding up
Science fiction writers have suggested a future Earth populated by a blend of all races into a common human form. In real life, the reverse seems to be happening.

Voyeurs put male fish off their ideal mate
Mating fish don't like an audience, it seems. When another male spies on them they change their mind about which female they prefer. The findings may alter the way we think about mate choice driving evolution

Present-day species of piranha result from a marine incursion into the Amazon Basin
About 4 million years BP, rise in sea level appears to have brought about the isolation of small populations of piranhas in the upper reaches of the great rivers. This situation favoured speciation and hence the formation of the present species.

Fossils Excavated From Bahamian Blue Hole May Give Clues Of Early Life
Long before tourists arrived in the Bahamas, ancient visitors took up residence in this archipelago off Florida's coast and left remains offering stark evidence that the arrival of humans can permanently change -- and eliminate -- life on what had been isolated islands, says a University of Florida researcher.
