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.

What I have learned from this book which was all about sex but sadly (the only sad thing) not hot:

1) One of the prime methods of classifications of animals is by their genitals. There might be a hundred different species of beetles that all look very similar, but their genitals will be very different.

2) I have also learned that research into male parts, partly because it is obviously easier, is extensive, but female bits have had scant scientific attention until recently.

4) Homosexuality in an

An insightful and frequently hilarious tour of research and the results of same in the comparative anatomy of genitalia across the animal kingdom, and its effect on evolution and vice versa. So it hits both science, and the history of science. A 2014 book, so nicely up-to-date. About a third of the page count is notes and bibliography, but the text is completely non-ponderous. Anyone inclined to complain about this or that aspect of human sexual behavior being "unnatural" really needs to read th

If you are a biologist, you will love this book. Even though I am a biologist there were many, many things I learned from this book that I had never known before, or had forgotten. So little of the fascinating sex lives of animals makes into textbooks. If you are not a biologist, but just enjoy learning new and strange things, you will also like this book. Herein you will learn about spermatophores (basically sperm bombs), the longest penises in the animal world relative to body size (the barnac ...more

Very entertaining book filled with fascinating information on sexual selection related primarily to genitalia. The author writes well and has a hearty sense of humor. The book has a strong emphasis on insects and small invertebrates, but the sections on humans, primates, ducks, and squirrels (my favorite) were informative and gave me a sense of how little we know about sex in vertebrates and how assumptions about the simplicity of it all are probably very wrong.

I actually listened to this on audiobook so I don't know if I can confidently say it's a "quick read" but it struck me as such. Some interesting stuff for a reader with a passing interest in evolution. One mild criticism is that the author, although not American, seems to know a thing or two about American politics and in general he criticized where I would like to see criticism (people freaking out that a study on duck sex is a waste of tax payer dollars; people saying that abortion should be i ...more

Why the hell did I pick up this book people ask. Was it for a course? That's the only logical non-sexual deviant reason people seem to come up with. No it wasn't for a course. But I admit I have nebulous reasons for wanting to read the book... apart from the title being sufficiently weird to get my attention. (See the Dictators Handbook and How to Run a Drug Cartel)

But a weird title does not mean a good book. I've learned to not entirely trust foreign born authors trying to write interesting sci

This book is about the evolution of genitals and the unanswered questions of sexual selection in general.

I thought that this was a great book for a number of reasons:
~The author's writing style is really entertaining. He makes a lot of references and uses colloquial terms that are familiar to the reader and even sticks in some funny turn of phrases.

~The book has a lot of novel information. The co-evolution of genitalia in the fight for dominance over reproduction is quite entertaining and the

An excellent look at the wild diversity of sex organs across the animal kingdom, which has a lot to say about how evolution works. It also suggests a lot of interesting starting points for building believable aliens who amount to more than a latex appliance glued to a human forehead! Who are truly alien. The author gleefully describes the many ways the shapes and functions of genitalia have been molded by complex Darwinian struggles, producing penises that have developed a daunting set of spines ...more

I found this book really quite fascinating. It was both informative, educating, and hilarious. The author realized that while the study of animal sex parts is useful and important science, it's also really rather funny. One of my favorite lines was in relation to those who suffer from hayfever: "few sufferers realize that they are reacting to clouds of birch ejaculate."
On the educating side of the book, it was really quite fascinating to learn about the wide variety of tactics used by different

This book was a great, interesting, and witty read. Highly recommended, but as with all biological research, be prepared for animal experiments/dissections/etc. -- there's no other way to get some of this information, but that doesn't mean I have to like it, or like that it happened.

I had high hopes for this book. Animal behavior is fascinating and animal sexual behavior is extremely so. I really enjoyed Chris Ryan's Sex at Dawn and was hoping for an education about the sexual practices of animals that was as satisfying as Ryan's book. Over the years I have learned about different aspects of animal sex, such as arms races that result in fly penises that have jagged edges and stick in the female, sperm competition in various animals, female baboons who trick the alpha male i ...more

-Audiobook version-
Book content + narrator: 4.5-5 stars

I am giving this book a 4.5-5 because I loved it. This is probably because it is my first real biological book read, and the amount of information is a lot and lots of new information flooded my brain and each time being awestruck. I have overlooked some of the things goodreads readers have mentioned in their reviews as I am probably not so familiar to the biology field books.. but one thing I was certainly uneasy about when he did not discu

This is my first serious non-fiction and I honestly couldn't have picked a better book! This well-thought out, perfectly organized, and comedic work dives in to the strange new faction of evolutionary biology that focuses on the evolution of genitalia. With jaw-dropping examples and extremely interesting allusions to other scientists' research, Menno Schiltuizen paints an immense, colorful picture of the strange and wonderful world we live in, and easily brings science into the reader's hands wi ...more

Shelves: natural-world, 2019
An engaging read, deriving from diverse sources, demystifying (to some length) the biological processes - of natural and sexual selection, esp the latter. Though "sex sells" is an adage that runs true, our general enlightenment on this is superficial, as a read of this book proves. The author dedicates a lot into the tiny details, which is great. The language - aimed to describe and conjecture the mating behaviors and organs of diverse lifeforms - leads to novel and bizzare phrases at times.

Confession: This is the third book I've read about animal sex. What is interesting about this book is that it focuses on genitalia specifically, not an all encompassing book about behavior, etc. It was fascinating to learn about how sexual selection is different from natural selection. Finally, his explanation about why there are male and female sexes in the first place blew my mind. This book was a definite nerdgasm.

Lots of crazy stuff on this planet, folks.
I will never eat a squid again.
Now I know why spiders are usually in a hurry during a certain time of year.
My only complaint is that it would have been nice to have some color plates added to this book.

Fascinating, but probably more than I really wanted to know about invertebrate sex. (The parts on birds and primates are interesting, too).

I guess when your main work concerns the sex organs of animals, you have to own a healthy sense of humor. That is why, even if I wasn't terribly interested in the subject, I continued to read the book mostly because of Menno Schilthuizen's writing style. This book - full title Nature's Nether Regions: What the Sex Lives of Bugs, Birds, and Beasts Tell Us About Evolution, Biodiversity, and Ourselves - kept being funny and captivating, despite being about a niche subject treated in a very scientif ...more

A fantastic journey into the fascinating world of animal reproduction and the unique, often bizarre structures and functions, mating behaviours, and physiological adaptations that exist. The author covers the full breadth of the Animalia, from the smallest invertebrates to humans, presenting some ground breaking, often controversial research and interpretation of the results. The writing is in a non-technical (when ever possible) format that is enjoyable to read, and in many places, very funny. ...more

As I'm nearing the end of this great book I have only a few remarks, some small points of criticism.
One is about the writing style, the author covers various hypothesis and discarded theories that were once used to explain various phenomena whereafter he continues by pointing out why these were later found to be inadequate.
All good, were it not for the fact that he describes the old theories in a way that make it sound as if they are still relevant today. One example being the "lock-key hypothes

I could have done without the too-cute asides and double entendres but there is a serious point to this celebration of genitalia and that is:

[S]tudying the evolution of genitalia has provided us with deep insights and spectacular panoramas on the history of life....

Somewhere in the deep folds of time, sex arose as a means to outrun fast-evolving viruses or help fix errors in the genetic code. Then a bacterium crawled into a primordial cell. To counter combat among cohabiting bacteria, separate m

The peculiar shapes of animal genitalia (mostly insects' genitalia) and methods of sexual congress – or at least of insemination – reveal the peculiar way that evolution has shaped the methods of reproduction. At the end the author admits that more attention has been paid, overall, to the peculiarities of the male member than has been paid to the female system, despite the fact that the female's sexual anatomy can be seen to drive the evolution of male structures, in both shape and method of del ...more

This book reads like a tongue-in-cheek textbook, which is how I wish all my textbooks had read. The author wants to make a point that genitalia and sexual behavior matter not just for evolution and survival, but also to draw parallels to our own human world. He reviews the research that has been done through the years and relates it to research now being done, including by him. His wit is sharp and I found myself reading parts aloud to my husband and both of us getting good laughs.

This was a fun read. The author shows the many ways that males and females of different species compete and cooperate in the serious game of propagation. The contest between the libidinous profligacy of males is contrasted with the selectivity of females, and a lot of attention is devoted to the ways in which the genders of different species attempt to genetically outwit each other. Females that eject unwanted sperm, males that plug the female orifice to block semen loss as well as other competi ...more

A solid four stars for the amazingly painstaking efforts by biologists that has led to the making of this book. I have renewed respect for biologists after reading Nature's Nether regions.

Charles Darwin introduced us to the theory of evolution, and others carried his work forward over the years. And yet, after having read this book, I felt that we might think we know evolution, but we really don't. For we know the effects of evolution, but the primary organs that bring about this change are stil

This is not necessarily a book that someone would look at and immediately purchase, however this is a piece of science literature that anyone could enjoy. I was often embarrassed to be reading it in public, so much so I removed the outer jacket, but I have shared all of my new animal sex facts with anyone who will listen. Schilthuizen is very entertaining, it was an easy read. If you find yourself in a bookstore, at least read the Afterplay, which discusses how something like slug sex is relevan ...more
