Showing results for "Sex" in Biology

In this fascinating and thought-provoking book, author Nick Lane brings together the latest research findings in the exciting field of mitochondria research to reveal how our growing understanding of mitochondria is shedding light on how complex life evolved, why sex arose (why don't we just bud?), and why we age and die. This understanding is of fundamental importance, both in understanding how we and all other complex life came to be, but also in order to be able to control our own illnesses, and delay our degeneration and death.

There is no one better qualified than Jared Diamond - renowned expert in the fields of physiology and evolutionary biology and award-winning author - to explain the evolutionary forces that operated on our ancestors to make us sexually different. With wit and a wealth of fascinating examples, he explains how our sexuality has been as crucial as our large brains and upright posture in our rise to human status.

In all animals, mating is a deal. But few creatures behave as if sex is a simple transaction. Many treat it with reverence, suspicion, angst and violence. In the case of the Black Grouse, the bird at the center of Matt Ridley’s investigation, the males dance and sing for hours a day, for several exhausting months, in an exhausting and sometimes deadly ritual called a ‘lek’. To prepare for the ordeal, they grow, preen and display fancy, twisted, bold-colored feathers.

International sex researcher, neuroscientist, and columnist Debra Soh debunks popular gender myths in this scientific examination of the many facets of gender identity that “is not only eminently reasonable and beautifully-written, it is brave and vital” (Ben Shapiro, number-one New York Times best-selling author).

A brilliantly engaging guide to the reproductive habits of creatures great and small. Narrated by the author, Dr. Carin Bondar. In The Nature of Sex, 'biologist with a twist' Carin Bondar presents the fascinating diversity of the reproductive habits of the animal kingdom and, through approachable explanations and humorous examples, succeeds in making an eternally popular subject into a book of international appeal.

We inherit mechanisms for survival from our primeval past - none so obviously as those involved in reproduction. The hormone testosterone underlies the organization of activation of masculinity: It changes the body and brain to make a male. It is involved not only in sexuality but in driving aggression, competitiveness, risk-taking - all elements that were needed for successful survival and reproduction in the past. But these ancient systems are carried forward into a modern world.

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.

A fascinating, bite-sized insight into how human sexuality came to be the way it is now - Jared Diamond explains why we are different from the animal kingdom. Why are humans one of the few species to have sex in private? Why do humans have sex any day of the month or year, including when the female is pregnant, beyond her reproductive years, or between her fertile cycles? Why are human females one of the few mammals to go through menopause?

Can twins have different fathers? From the composition and function of human sex organs to the fascinating biochemistry behind sexual attraction, How Sex Works presents captivating new ideas and surprising answers to questions about contraception, fertility, circumcision, menopause, STDs, homosexuality, orgasms, and more. This is an entertaining, comprehensive exploration of culture, biology, and history that takes us far beyond our common understanding of sex.

With curiosity and wit, Ina Park's Strange Bedfellows rips back the sheets on the mysteries of what happens when STDs enter the sack.

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?
