In the animal kingdom, sperm usually are considerably smaller than eggs, which means that males can produce far more of them. Large numbers of tiny sperm can increase the probability of successful fertilization, especially when females mate with several males.

Strange Sea-Dwelling Reptile Fossil Hints at Rapid Evolution After Mass Extinction

115995_web.jpg

Two hundred and fifty million years ago, life on earth was in a tail-spin--climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child's play. Marine life got hit hardest--96% of all marine species went extinct. For a long time, scientists believed that the early marine reptiles that came about after the mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question.

Why Is Female Sexuality More Flexible Than Male Sexuality?

A new evolutionary theory argues that women may have been evolutionarily designed to be sexually fluid--changing their sexual desires and identities from lesbian, to bisexual, to heterosexual and back again--in order to allow them to have sex with their co-wives in polygynous marriages, therefore reducing conflict and tension inherent in such marriages while at the same time successfully reproducing with their husbands in heterosexual unions.
