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, ...

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.

In the framework of an international research project, a team of scientists have demonstrated for the first time that asexual reproduction can be successful in the long term. The animal they studied ...

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, ...

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 ...

(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 ...

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 ...

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, ...
