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 ...

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 ...

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 ...

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 ...

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 ...

(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 ...

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 ...

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 ...

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, ...

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 ...
