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 ...

Evolutionary biologists at the University of Toronto have found that environment plays a key role in determining whether a species opts for sexual over asexual reproduction. The study, led by ...

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, ...

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 ...

Sexual reproduction is costly to organisms that depend on it, like humans. In contrast, bacteria reproduce by asexual reproduction, which is more efficient but doesn't allow genomic mixing, making ...

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 ...
