The Dawn of the Deed: The Prehistoric Origins of Sex
Sinopsis :
We all know about the birds and the bees, but what about the
ancient placoderm fishes and the dinosaurs? The history of
sex is as old as life itself&#8212an as complicated and
mysterious. And despite centuries of study there is always
more to know. In 2008, paleontologist John A. Long and a
team of researchers revealed their discovery of a placoderm
fish fossil, known as &#8220thmother fish,&#8221which at 380
million years old revealed the oldest vertebrate
embryo&#8212th earliest known example of internal
fertilization. As Long explains, this find led to the
reexamination of countless fish fossils and the discovery of
previously undetected embryos. As a result, placoderms are

now considered to be the first species to have had intimate
sexual reproduction or sex as we know it&#8212or of.Inspired
by this incredible find, Long began a quest to uncover the
paleontological and evolutionary history of copulation and
insemination. In The Dawn of the Deed, he takes readers on
an entertaining and lively tour through the sex lives of ancient
fish and exposes the unusual mating habits of arthropods,
tortoises, and even a well-endowed (16.5 inches!) Argentine
Duck. Long discusses these significant discoveries alongside
what we know about reproductive biology and evolutionary
theory, using the fossil record to provide a provocative account
of prehistoric sex. The Dawn of the Deed also explores
fascinating revelations about animal reproduction, from
homosexual penguins to monogamous seahorses to the
difficulties of dinosaur romance and how sexual organs in
ancient shark-like fishes actually relate to our own sexual
anatomy.The Dawn of the Deed is Long&#8217own story of
what it&#8217like to be a part of a discovery that rewrites
evolutionary history as well as an absolutely rollicking guide to
sex throughout the ages in the animal kingdom.
It&#8217natural history with a naughty wink.
