This woman goes in for a facelift and the doctor says: "We've got this new method: I put a knob in the back of your head, and every time you feel like you need a lift, just turn it."
She gets the knob implanted and is beautiful for five years.
But one day she notices a problem and returns to the doctor.
"I've got these huge bags under my eyes," she complains.
The surgeon replies: "Those aren't bags; those are your breasts."
"Ah," she sighs. "That explains the goatee."
Willi HennigBorn 20 Apr 1913; died 5 Nov 1976 at age 63.German zoologist who proposed cladistics (Greek=branch) for the hierarchical classification of species, based on phylogeny - the evolutionary history - of the ancestors. He wished to deal with deficiencies in the system originated by Linnaeus. Hennig published a new system in his book, Theorie der phylogenetischen Systematik in 1950. Cladistics regards all new species to have evolved by descent with modification. After an evolutionary branching, some shared derived characteristics are retained. Thus the evolutionary history of current organisms can be traced back, connecting through shared ancestors to lineages of other organisms. For example, the even-toed foot of the deer, camels, cattle, pigs and hippopotamus is a homologous similarity indicating a common ancestor.« |
