A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those ...

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, ...

SMBE Journals (Molecular Biology and Evolution and Genome Biology and Evolution) Further analysis of PifA and PifB revealed that they exhibit many of the characteristics of eukaryotic host-associated ...

Some plants bend the rules of plant life so far that they barely resemble plants at all. Balanophora is one of them - a ...

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 ...

Evolutionary biologists have found that environment plays a key role in determining whether a species opts for sexual over asexual reproduction. Evolutionary biologists at the University of Toronto (U ...

(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 ...

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 ...

Researchers have discovered a biological shocker: female boa constrictors are capable of giving birth asexually. But the surprise doesn’t end there. The study in Biology Letters found that boa babies ...

Birds do it. Bees do it. But until now, no one thought the fungus farming ant did it. Documenting genetic variations and the presence of sperm, however, researchers have found evidence that some ...
