All-female animal species bring to question the advantages of sex, but some all-female species reveal the importance of sex, even when no males exist at all. So what's the point of sex? Rachel removes males from the equation to discuss these big questions on this week's episode. PS: Sorry in advance for all of the genetics. :P
See us in person at the Sedgwick County Zoo on Feb 15 for Loves Bites! 21+ only. Tickets include cocktails and hors d'ouevres. Buy tickets.
Also, this is a formal apology for all of the genetics verbage. Scroll for lady lizards banging. Love, Rachel.

PARTHENOGENESIS =/= CLONING (always)
These species of obligate parthenogenetic animals are all females. No males exist at all in the species. Marbled Crayfish are an invasive species, and Warramaba virgo exhibit the same or more genetic diversity compared with sexual Warramaba species!!
