(Mutations do create a minor amount of change.) If asexual reproduction survives at all, conditions must sometimes favor it, even in competition for a niche with sexually reproducing species.

Developmental biology also encompasses the biology of regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism.

The finding may offer insight into a long standing question in evolutionary biology about what forces cause species to choose sex over asexual reproduction and vice versa, he said. On paper, ...

Those outlier liaisons gave whiptails robust heterozygosity, which has been preserved by the identical replication—essentially, cloning—that occurs in asexual reproduction. It’s a genetic ...

Regeneration is a remarkable biological ... which includes organs and structures. Asexual reproduction: Some species can reproduce asexually through fragmentation, where each fragment regenerates ...
