Amazon mollies don't need a man, and never will. A new study finds they can purge and repair genetic mutations that would ...

Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, ...

Evolutionary biologists at Skoltech have discovered recombination in bdelloid rotifers, microscopic freshwater invertebrates characterized by their presumed ancient asexuality. The existence of such ...

In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome ...

(Santa Barbara, Calif.) Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual ...

Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new research. An ...

BROOKFIELD, Ill. (Gray News) – A shark at the Brookfield Zoo in Illinois was born through asexual reproduction, something so rare that experts believe it’s only the second time it has ever happened at ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

The California condor is one of the rarest birds in the world, but now it seems that nature is giving it an unexpected leg-up. Scientists have discovered two condor chicks that were born from ...
