As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Chickens and turkeys 'closer to dinosaur ancestors' than other birds

Summary:
New research suggests that chickens and turkeys have experienced fewer gross genomic changes than other birds as they evolved from their dinosaur ancestor.

Professor Darren Griffin and a team at the University's School of Biosciences have conducted research that suggests that chromosomes of the chicken and turkey lineage have undergone the fewest number of changes compared to their ancient avian ancestor, thought to be a feathered dinosaur.

The Kent research is part of a study by a consortium of leading scientists into avian or bird genomes, which tell a story of species evolution. The living descendants of dinosaurs were thought to have undergone a rapid burst of evolution after most dinosaur species were wiped out. The detailed family tree of modern birds has however confused biologists for centuries and the molecular details of how birds arrived at the spectacular biodiversity of more than 10,000 species is barely known.
