New York : Dismissing the common perception that evolution happens only over time, a team of US researchers says they have observed an episode of evolution happening under their nose, reports IANS.
In research with a population of guppies, the scientists observed male colour patterns impacting their ability to make babies and survive longer.
Working in a river in Trinidad, the researchers determined which male guppies would contribute more offspring to the population as well as which would live longer and which would have a shorter lifespan.
“We are detailing how evolution happens,” said David Reznick, professor of biology at University of California, Riverside. “Usually people look at evolution as change over time but they do not know the details of how it changes,” Reznick noted.
