Nature is full of wonders, and some of the most amazing surprises come from how animals reproduce. While most of us think ...

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 leopard shark in a Queensland aquarium has shocked scientists by being the first in the world to give birth without a male, after previously mating in the usual way. The shark at Townsville's Reef ...

Sexual reproduction implies high costs, but it is difficult to give evidence for evolutionary advantages that would explain the predominance of meiotic sex in eukaryotes. A combinational theory ...

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 ...

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 ...

A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. Farmers throughout the world spend ...
