New dinosaur with heart-shaped tail offers clues to evolution of Africa's ecosystems（图）
New dinosaur heart-shaped tail evolution of Africa ecosystems
2019/11/22
A dinosaur that wore its "heart" on its tail is providing new clues to how ecosystems evolved on the African continent during the Cretaceous Period some 100 million years ago, according to researchers...
Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That’s...

Fertilizer Dearth Foiled Animal Evolution Eons
2017/1/9
For three billion years or more, the evolution of the first animal life on Earth was ready to happen, practically waiting in the wings. But the breathable oxygen it likely required wasn’t there, and a...

evolution phenomenon puzzled Darwin
2016/12/13
Why do some animals have extravagant, showy ornaments — think elk and deer antlers, peacock feathers and horns on dung beetles — that can be a liability to survival? Charles Darwin couldn’t figure it ...
Complete Mitochondrial Genome Sequences of Chinese Indigenous Sheep with Different Tail Types and an Analysis of Phylogenetic Evolution in Domestic Sheep
Mitochondrial DNA Mitogenome Sheep Phylogenetic Mitochondrial Control Region
2016/5/20
China has a long history of sheep (Ovis aries [O. aries]) breeding and an abundance of sheep genetic resources. Knowledge of the complete O. aries mitogenome should facilitate the study of the evoluti...

A New Leptoceratopsid (Ornithischia: Ceratopsia) from the Upper Cretaceous of Shandong, China and Its Implications for Neoceratopsian Evolution
A New Leptoceratopsid Neoceratopsian Evolution
2014/3/26
The leptoceratopsids are a group of small, quadrupedal horned
dinosaurs. They normally have a total body length of about two
meters, and are thus much smaller than the contemporary
ceratopsids [1]....
