(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 ...

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 ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

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 ...

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 ...

Two novel hypotheses have been proposed that address the 'two-fold cost of sex': one of the biggest enigmas in the evolution of sexual reproduction. Two novel hypotheses have been proposed that ...

The Pro1 protein helps express mating-related genes in different species of fungi. But what happens when Pro1 malfunctions? Researchers from the Tokyo University of Science have found that mutations ...
