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, ...

Stick insects that reproduce asexually cannot adapt as quickly in the course of evolution as sexually reproducing species, leading to a decrease in biological diversity, according to new research. An ...

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 ...

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 ...

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 ...

Thousands of species produce genetically identical (clonal) offspring through asexual reproduction 1. However, asexual reproduction is much less common than sexual reproduction is, partly because it ...

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 reproduction has many ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm’s DNA. I describe ...
