Reproduction is a normal part of life, and while sex might seem like a quick and straightforward process for humans, that’s not always the case in the animal kingdom. Some animals reproduce in rougher ...

A study has found that the reason why the evolution of the first animals to appear on Earth was delayed for over 10 million years was due to their reproductive methods. Early animals reproduced by ...

Nature is full of wonders, and some of the most amazing surprises come from how animals reproduce. While most of us think that having babies always requires a male and a female, that’s not true for ...

Imagine if humans could do that—no need for a partner or complicated dating processes. Just think of the possibilities! wink, wink. Cloning in animals refers to asexual reproduction, where an organism ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm's DNA. I describe ...

How do animals decide when to fight and when to walk, fly, slither, or swim away? Most research on animal conflict has focused on the short-term costs of single interactions, but a pair of behavioral ...

The common fruit fly normally needs a mate to reproduce. But scientists tinkering with its genes found the ones that can induce parthenogenesis, or virgin birth. For the first time, scientists ...

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 ...

Fossils from some of the oldest-known animals on Earth, dating from 574 million years ago (Ediacaran period), suggest that cloning, not competition, dominated the Ediacaran seas, slowing evolution ...

Not all species need sperm to fertilize an egg for sexual reproduction. Some species need sperm in order to induce completion of egg nucleus development, but then never use the sperm’s DNA. I describe ...
