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.

For most living things, sexual reproduction has proven the best overall strategy to perpetuate a species in the rough-and-tumble, unpredictable fray of natural selection. With two partners combining ...

A team of scientists has sequenced, for the first time, a tiny worm that belongs to a group of exclusively asexual species that originated approximately 18 million years ago -- making it one of the ...

Named for its ropy-looking long branches, Aplysina cauliformis, a coral reef sponge, provides a critical 3D habitat for marine organisms and helps to stabilize the foundation of coral reefs. However, ...

(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 ...

Nature's reproductive wonders are revealed as several female animals, including Komodo dragons, sharks, and even birds like California condors, can re ...

Sexual reproduction implies high costs, but it is difficult to give evidence for evolutionary advantages that would explain the predominance of meiotic sex in eukaryotes. A combinational theory ...

Oribatid mites, minuscule soil-dwelling creatures, have been decomposing organic matter for millions of years. With over 10,000 known species, they were among the earliest arthropods to colonize land, ...

Say a thank you to the pathogens and parasites of the world: Without them, there might be no such thing as sex. A new study finds that in organisms that can reproduce alone or with a partner, sexual ...

New research suggests that sexual reproduction is favored by selection because, unlike asexual reproduction, it not only provides important evolutionary advantages in constantly changing environments, ...
