Many reptile species have their sex determined by incubation temperature rather than genes Lizards, crocodiles and turtles have some rocky times ahead. Warming temperatures have the potential to ...

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 ...

Conventional wisdom holds that sexual reproduction evolved because it enables organisms to shuffle, or recombine, different alleles (versions of a gene) in the next generation, producing the genetic ...

Scientists at deCODE genetics/Amgen have constructed a complete map of how human DNA is mixed as it is passed down during reproduction. The map marks a major step in the understanding of genetic ...

Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated. The ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? For years, scientists have split neoaves (which make up 95 percent of bird species) ...

Researchers at the University of California have created a novel data structure and compression method that allows ...

Understanding biological relationships is often critical when studying animal populations. Researchers have now developed a transformative approach that identifies stretches of DNA that two ...
