Just as humans procreate, animals have their own way of getting it on, too! Some ways are quite unexpected, from the cannibalistic mating practices of the praying mantis to the complicated sex life for snails with backwards organs.

What does it mean to be female? Mother, carer, the weaker sex? Think again. In the last few decades a revolution has been brewing in zoology and evolutionary biology. Lucy Cooke introduces us to a riotous cast of animals, and the scientists studying them, that are redefining the female of the species. Meet the female lemurs of Madagascar, our ancient primate cousins that dominate the males of their species physically and politically. Or female albatross couples, hooking up together to raise their chicks in Hawaii.

Evolutionary biologist Nathan H. Lents takes listeners on a journey from silent crickets to lesbian albatrosses to bonobos who kiss, revealing what this incredible array of sexual diversity can teach us about our own. Amusing, enlightening and meticulously researched, Lents convincingly shows that diverse genders and sexuality have evolutionary functions far beyond procreation. The Sexual Evolution is a perspective-altering book that advocates understanding and demolishes biases held by even the most open-minded among us.

The story of evolution as you’ve never heard it before. What’s the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Menno Schilthuizen invites listeners to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles.

Written in a brilliantly engaging style by biologist Jules Howard, this fascinating and highly engaging work covers the how and why of sex on Earth, in all its diversity. From sperm wars to cuckoldry, hermaphrodites and virgin births, spent males, racy harems, clitoral births, hips, breasts and birdsong, penis-percussion, and those riskiest and most elusive of all traits, monogamy and true love, all this and more is discussed in Sex on Earth, as Jules takes us on a voyage of discovery of the ins and outs of animal reproduction.

While we joke that men are from Mars and women are from Venus, our gender differences can't compare to those of other animals. For instance: the male garden spider spontaneously dies after mating with a female more than fifty times his size. Female cichlids must guard their eggs and larvae--even from the hungry appetites of their own partners. And male blanket octopuses employ a copulatory arm longer than their own bodies to mate with females that outweigh them by four orders of magnitude. Why do these gender gulfs exist?
