Researchers have found that targeted delivery of messenger RNA (mRNA) can restore sperm production and fertility in genetically infertile male mice.

Ducks display one of the most studied examples of sexual conflict in vertebrate evolution. In several species, males evolved elongated corkscrew shaped genitalia associated with forced copulation ...

The earliest ancestors of all backboned animals, including humans, may have viewed the world with four eyes, not just two. The remnants of those extra eyes persist in the human brain today as the ...

The earliest recorded vertebrates had four eyes to escape predators in the ancient Cambrian ocean, according to half-a-billion-year-old fossils from China that shed light on our evolutionary origins.

NASHVILLE, Tenn. (WSMV) - A Tennessee bill seeks to expand the definition of what constitutes a “person” to begin at the point of fertilization. Currently in Tennessee, a “person” legally includes an ...

Scientists have uncovered a surprising genetic shift that may explain how animals with backbones—from fish and frogs to humans—became so complex. By comparing sea squirts, lampreys, and frogs, ...

New research from the University of St Andrews has discovered a crucial piece in the puzzle of how all animals with a spine - including all mammals, fish, reptiles and amphibians - evolved. In a paper ...
