“However, less-fit lineages also routinely leapfrog over strains of higher fitness. Our results demonstrate that this combination of factors, which is not accounted for in existing models of evolutionary dynamics, is critical in determining the rate, predictability and molecular basis of adaptation.” If Darwinism mattered the way it used to, this would be heresy.
Some researchers wondered whether all that junk DNA supposedly left over from Darwinian evolution actually did something after all so they tested the idea: Patches of seemingly meaningless DNA dotted throughout the genome might actually have a function: helping cells to survive starvation. Two studies published in Nature on 16 January suggest that these stretches […]
Not by adding to it. Everyone seems to be talking about devolution (“reductive evolution”) these days. From ScienceDaily: “This is the first large genome project like this that actually looks at hundreds of different eukaryotic species, not different individuals or isolates of the same species,” says Chris Todd Hittinger, a UW-Madison genetics professor and one […]
From Sukanya Charuchandra at The Scientist: Two species of yeast, one of which is used in the biotechnology and food industries to make bioethanol and sourdough bread, while the other causes yeast infections, have been found to be one and the same, according to research published in PLOS Pathogens today (July 19). And, the researchers […]
