O.K. – so I was the last person on the planet to see E.T., I still watch TV on a cathode ray tube, and I’m seven years late reading Olivia Judson’s hugely entertaining, accessible, not to say stimulating, guide to evolutionary biology: Dr.Tatiana’s Sex Advice to All Creation, making this an admittedly after-the-event review, but a recommendation all the same.

Throughout the guide, Judson stays in character as sex therapist Dr Tatiana, helping all manner of creatures out with their sex problems – agony aunt style.

And creatures it is.  Ranging from a stick insect jaded with the tedium of ten week copulations; to a praying mantis who finds sex so much more satisfying after biting off her lover’s head; to a fruit fly dismayed that he’s run out of sperm; to a queen bee’s concern that her mates leave their genitalia inside her after sex.

Mixed in with these familiar heterosexual and homosexual practices are gang rape, cannibalism, self-sacrifice, and deception – all to a background of hopeless promiscuity.

The entertainment is delivered by a fascinating cast of cads, bints, sluts, and whores, bonking away at romantic locations  – including the inside of a rat’s intestines.

That’s the language and tone then: spirited rather than crude I’d say, but probably not first choice for your great gran.

The anthropomorphism is extreme, caricatured, and humorous enough to make any questions around ambiguity and appropriateness non-issues (at least for me).   It’s clever too, each section introducing a discussion on an aspect of evolutionary biology with some fun, if not a giggle, then quickly morphing into serious, yet always palatable, science.

The concepts are familiar: sex ratios, altruism, asexual vs sexual reproduction, dangers of recessive genes and such like; so perhaps I’ve not been under a log after all.  I kept getting flashbacks to ideas I’d first read about in Richard Dawkins’s Selfish Gene or Matt Ridley’s The Red Queen.  By comparison, Judson’s style in the guise of Dr Tatiana is deliberately and overtly entertaining; but not at the cost of scholarly rigor (there are 62 pages of  Notes and Bibliography).

Previous reading certainly didn’t stop me picking up a bunch of new facts and figures on the more macabre and icky side of sexual reproduction.  Knowledge any schoolboy/girl  would be proud to have in his/her  armoury.

Insects dominate Dr Tatiana’s surgery hours, but mammals and birds  do get a look in.   Like the girl hyena concerned over the size of her pseudo-phallus, or the moorhen bemused that his girlfriends are always fighting with each other.

But now I’m giving too much away.

Amazon have the paperback Dr Tatiana on for about £6.50 in the UK, and there’s also a DVD of the TV series based on the book.  No brainer – go get it!
