"Our work has changed many traditional views on the evolutionary history of birds," said Zhang Guojie from Zhejiang University. "This new family tree will serve as a solid backbone for mapping the evolutionary history of all bird species with important implications for ornithological research and bi...
Thanks to amazing new fossil discoveries in China, the evolutionary history of birds has become clearer, even though bird bones do not fossilize as well as those of other vertebrates. As we’ve seen earlier, birds are highly modified diapsids, but rather than having two fenestrations or openin...

Aim The global species richness patterns of birds and mammals are strongly congruent. This could reflect similar evolutionary responses to the Earth's history, shared responses to current climatic conditions, or both. We compare the geographical and phylogenetic structures of both richness gradients to...
This phylogenetic result may imply a complex evolutionary history of basal birds. To our knowledge, FPDM-V-9769 represents the first record of the Early Cretaceous non-ornithothoracine avialan outside of the Jehol Biota and increases our understanding of their diversity and distribution during the ...

Pre-human New Zealand had some unusual feeding guilds of birds (e.g. the herbivorous moa fauna), thought to have developed as a result of the absence of a 'normal' mammal fauna. Insectivorous birds, on the other hand, are an integral part of all the world's ecosystems, regardless of ...
They are highly regulated throughout different stages of development in a tissue-specific manner. The number and type of α- and β-globin genes varies between jawed vertebrates. In teleosts and amphibians α- and β-like globin genes are clustered together, but in birds and mammals these ...
