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 ...

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 ...

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 ...

If you’ve ever had a spiny leaf insect as a pet, or you’re considering getting one, hopefully someone has warned you about this: if you put one in your enclosure, you might come back some time later ...

(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 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 ...

In the debate over human origins and the nature of sexual reproduction, religious and scientific perspectives often diverge. The Bible claims man came first, with women derived from man’s rib. Yet, ...
