Analyzing DNA from the bones of chickens that lived 200-2300 years ago in Europe, researchers report that just a few hundred years ago domestic chickens may have looked far different from the chickens we know today. The results suggest that some of the traits we associate with modern domestic chickens -- such as their yellowish skin -- only became widespread in the last 500 years, much more recently than previously thought. "It's a blink of an eye from an evolutionary perspective," said co-author Greger Larson at Durham University in the United Kingdom. The study is part of a larger field of research that aims to understand when, where and how humans turned wild plants and animals into the crops, pets and livestock we know today. Generally, any mutations that are widespread in domestic plants and animals but absent from their wild relatives are assumed to have played a key role in … Continue reading →

Neanderthal skulls. Image by leted via Flickr Scientists have increasingly realized that DNA is only part of what makes us us perhaps equally important is how our genes activity is modified by a process called epigenetics. Recently this cutting-edge field has turned its attention to some very old DNA: Researchers today announced they have reconstructed methylation maps for our extinct relatives. The findings might explain certain differences in appearances between Neanderthals, Denisovans, and us, as well as the prevalence of disease. Epigenetics is a branch of science that explores how the expression of our DNA can be influenced by external factors without the DNA itself changing. Research in the field has focused on DNA methylation. This is when a chemical compound called a methyl group attaches to DNA. This can regulate an individuals genetic expression and even be passed down through generations. DNA methylation has been linked to disease and also to an individuals appearance and behavior. This is the first time, however, that an archaic pattern of methylation has been reconstructed for early humans. Researchers set out to reconstruct the DNA methylation activity of Neanderthals and Denisovans, two species of archaic human that split from modern humans more than … Continue reading →
