Vertebrate morphology exhibits remarkable diversity, reflecting a complex interplay of developmental processes, genetic regulation and environmental pressures. This variation arises from a combination ...

Many of the ancient southern Africans, including those who lived between about 10,200 and 1,400 years ago, "fall outside the ...

The present theory offers a unified solution to three closely related evolutionary problems. (1) Why does an evolving population explore only a small fraction of the accessible pathways in genotype ...

On November 24, 1859, Charles Darwin published On the Origin of Species and transformed our understanding of life on Earth by ...

A recent statistical study has revealed some of the constraints and directions in the evolution of the structure and function of proteins. Better models of protein structural dynamics may allow ...

A genomic study of human and selected nonhuman primate centromeres has revealed their unimaginable diversity and speed of evolutionary change. Although centromeres are vital to proper cell replication ...

Discover interesting facts about how evolution works, the different patterns that can emerge from evolution, how quickly organisms can evolve, and whether evolution is a random or ordered process When ...

Mammal species diversified more rapidly early in their history – peaking roughly 66 million years ago – before a long-term decline in diversification punctuated by diminishing bursts of evolutionary ...
