WASHINGTON — An all-female freshwater fish species called the Amazon molly that inhabits rivers and creeks along the Texas-Mexico border is living proof that sexual reproduction may be vastly ...

The study reveals how Balanophora plants function despite abandoning photosynthesis and, in some species, sexual reproduction. Their plastid genomes shrank dramatically in a shared ancestor, yet the ...

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 ...

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 ...

Some animals reproduce only once before dying. This life strategy, called semelparity, sees organisms channel all energy into ...

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 ...

In times of desperation, female sawtooth sharks have been known to reproduce sans males. For other species, solo reproduction is downright vanilla. blickwinkel / Alamy When it comes to getting ...

Lineages of insects rife with sex conflict have split into at least four times as many species compared with related lineages with less conflict, report Göran Arnqvist and his colleagues at the ...
