Named for its ropy-looking long branches, Aplysina cauliformis, a coral reef sponge, provides a critical 3D habitat for marine organisms and helps to stabilize the foundation of coral reefs. However, ...

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 ...

Scientists who study how organisms reproduce know that asexual reproduction is more efficient for one thing, it’s about twice as fast as sexual reproduction, since every offspring can produce more.

In the course of evolution, animals have repeatedly shifted from sexual to asexual reproduction. The first evidence of the consequences of parthenogenesis – a type of asexual reproduction – on genome ...

A team of scientists has sequenced, for the first time, a tiny worm that belongs to a group of exclusively asexual species that originated approximately 18 million years ago -- making it one of the ...

Fractofusus fossils The earliest evidence for reproduction in a complex organism had two surprisingly sophisticated modes of reproduction. The creatures, known as rangeomorphs, lived 565 million years ...

It’s a rare and fascinating event: the world’s largest geckos have laid eggs without any males involved, thanks to parthenogenesis. This documentary dives deep into the science behind asexual ...

The California condor is one of the rarest birds in the world, but now it seems that nature is giving it an unexpected leg-up. Scientists have discovered two condor chicks that were born from ...

Before the birds and the bees, there was Fractofusus, a prehistoric creature that scientists think was the first organism to use complex methods to reproduce, rather than just asexually multiplying.
