A common parasite expands across species by abandoning sex, boosting short-term spread while risking long-term collapse.

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, ...

For the first time, researchers have observed two cases of asexual reproduction in condors. And it also turns out that whales ...

Not all creatures need to breed to produce offspring. Animals like zebra sharks and killifish are redefining what scientists thought they knew about asexual reproduction. Among vertebrates, or animals ...

Lord Howe Island is an isolated high latitude reef representing the southern limit of reef-building coral distribution on the East Coast of Australia. It is located over 600 km from the mainland coast ...

(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 ...

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 ...

Australian researchers have uncovered how a particular strain of a diarrhea-causing parasite managed to infect more animal ...

Scientists who study how organisms reproduce know that asexual reproduction is more efficient for one thing, it’s about twice as fast as sexual reproduction, since every offspring can produce more.

A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. Farmers throughout the world spend ...

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 ...

Two captive female California condors each produced a chick asexually years ago – the only such instances ever recorded for that endangered species, researchers reported Thursday. And while this has ...
