An ancient bird preserved in a Siberian permafrost deposit has a partial mitochondrial gene that 100 percent matches that of the present-day horned lark (Eremophila alpestris), according to a study published on February 21 in Communications Biology. The bird was genetically identified as a female and radiocarbon dated to approximately 44,000–49,000 years old.
“Not only can we identify the bird as a horned lark,” says coauthor and zoologist Nicolas Dussex of Stockholm University in a press release. “The genetic analysis also suggests that the bird belonged to a population that was a joint ancestor of two subspecies of horned lark living today, one in Siberia, and one in the steppe in Mongolia. This helps us understand how...
