Birds do it, a few bees get to do it – but how did sexual reproduction evolve in the first place? An evolutionary model suggests that it could have started as a way for two cells to pool their ...

Scientists have discovered a sexual reproduction process in microalgae that helps them better understand algae and plant evolution. Their discovery could lead to new industrial applications for ...

The evolution of sexual reproduction in living beings is one of the biggest mysteries in biology. There are two known modes of reproduction: asexual, where the organism creates clones of itself, and ...

Recombination and sexual reproduction lie at the heart of evolutionary innovation, reshuffling alleles to generate genetic diversity and enabling populations to adapt to shifting environments. Meiotic ...

Studying a species of beetle mite, an international research team has demonstrated for the first time that animals can survive over very long periods of time (possibly millions of years) entirely ...

THERE’S no way sex could ever be considered a good solution for reproduction among organisms like us- eukaryotes with complex information contained within membraned cells. After all, the exponential ...

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 ...

In terms of population growth speeds, asexual animals have a significant advantage: so why do so many species use sexual reproduction to propagate? One of the basic evolutionary weapons in the arsenal ...

(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 ...
