The Evolution of Dark-Fly

dark-fly.gif

On November 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than sixty years later, the descendents of those flies have adapted to life without light. These flies—a variety now known as “Dark-fly”—outcompete their light-loving cousins when they live together in constant darkness, according to research reported in the February issue of G3: Genes|Genomes|Genetics. This competitive difference allowed the researchers to re-play the evolution of Dark-fly and identify the genomic regions that contribute to its success in the dark.

Mating Behaviour in the Natural World Contradicts Darwin’s Idea That Females Make the Decisions, Researchers Find

A provocative study by evolutionary biologists at McMaster University takes on one of Charles Darwin’s central ideas: that males adapt and compete for the attention of females because it is the females who ultimately choose their mates and the time of mating.

Why Do Some Fish Thrive in Oil-Polluted Water?

dirtyeprouvetteresized.jpg

When scientists from McGill University learned that some fish were proliferating in water polluted by oil extraction in Southern Trinidad, they thought they had found a rare example of a species able to adapt to crude oil pollution. But when they tested them, these guppies were actually less adapted to pollution than similar fish from non-polluted areas.

Evolutionary Clock Ticks for Snowshoe Hares Facing Climate Change

Having the wrong coat color during shorter winters is deadly for snowshoe hares and could lead to a steep population decline by mid-century. However, wide variance in molting times could enable natural selection to work.

Aches and Pains? Evolution’s Way of Saying “Stay Home”

When sick, we assume that our aches, fever, etc., are from a virus or bacteria, but now a team of scientists have a novel hypothesis: evolution. The genes that trigger symptoms which encourage us to stay home are actually focused on their own survival – in the group as a whole, if not in us.

Study Finds People Transformed How Species Associated After 300 Million Years

woods1993.jpg

A study published today finds a surprising and very recent shift away from the steady relationship among species that prevailed for more than 300 million years. The study, published in the journal Nature, offers the first long-term view of how species associated with each other for half of the existence of multicellular life on Earth.
