Snakes, like most reptiles in the world, are oviparous. This means that rather than producing live young ones, the way mammals do, snakes produce an immature single cell — an egg. Most snakes follow ...

Some animals, like Komodo dragons and sharks, were found to reproduce without mating, a process termed parthenogenesis. California condors, stick insects, blind snakes, tardigrades, and some fish have ...

A new study published in Science and led by Monash University biologists reveals that the energy cost of reproduction is far greater than previously believed. The research, led by Dr. Samuel C Ginther ...

In a lab at the University of Sydney, a female yellow-bellied three-toed skink first laid eggs, then gave birth to a live baby, all part of the same pregnancy. This is the first time biologists have ...

Researchers led by the University of Cambridge have found the earliest example of reproduction in a complex organism. Their new study has found that some organisms known as rangeomorphs, which lived ...

The genetic structure of natural populations is influenced by natural selection, migration, genetic drift and mating systems (modes of reproduction). The relative importance of these factors varies ...

Researchers at Max Planck Institute for Biology Tübingen and Kobe University discovered populations of female brown algae that reproduce from unfertilized gametes and thrive without males. In a study ...

Melanie Laird receives funding from The University of Otago. Camilla Whittington receives funding from the Australian Research Council. University of Sydney and University of Otago provide funding as ...

"This book is published on the occasion of the Royal Entomological Society's International Symposium on 'The Evolution of Insect Mating Systems' in St. Andrews, September 4-6, 2013. All symposium ...

In order to evaluate the relative importance of asexual and sexual reproduction to the fitness of a clonal organism, matrix projection models were used to quantify the contributions of each of these ...

Scientists have documented the first "virgin birth" in a crocodilian—and the discovery suggests that dinosaurs may have also had this unusual ability. In a study published in the Royal Society journal ...

Root-knot nematodes (RKN) of the genus Meloidogyne are biotrophic plant parasites of major agricultural importance, which exhibit very variable modes of reproduction, from classical amphimixis to ...
