Latest Evolution of sexual reproduction Stories
From protozoans to mammals, evolution has created more and more complex structures and better-adapted organisms.
Battles of sexes shown to spur adaptive sex differences
Courtship rituals can be all-consuming, demanding time and effort – but now scientists have discovered why it might be worth it.
The role of sex in driving genetic variation and generating higher biodiversity has been debated for over a century.
Biology textbooks maintain that the main function of sex is to promote genetic diversity.
A multicellular green alga, Volvox carteri, may have finally unlocked the secrets behind the evolution of different sexes.
What's so great about sex? From an evolutionary perspective, the answer is not as obvious as one might think. An article published in the July issue of the American Naturalist suggests that sex may have evolved in part as a defense against parasites.
The utility of sex, according to an intriguing new theory of evolutionary biology, may be its ability to promote genes that play well with many other partners rather than those that shine with just one specific set of genes.
A biologist at The University of Texas at Austin has presented a new theory that sheds light on how organisms, including viruses like HIV, rapidly evolve in the face of vaccines and antibiotics.
