They used Great T**s from non-urban and urban areas, and mixed them up through breeding, to rule out any possible family history of telomere length. In this study, published in the journal Proceedings of the National Academy of Sciences, a group of juvenile zebra finches was allowed to interact with an adult. an, Michal Porteš, W.

This has happened before, Archaeopteryx and the bird family tree have had an often tenuous relationship. But it is utterly bewildering to me to see news reports about this recent science that read “… An icon knocked from its perch&# or “Archaeopteryx no longer first bird.&# What evolved into what?
