Cradle of Man: With intelligent design worming its way through academia, we could really use a good evolution play that looks at the natural history of man. But even with its promising title, Melanie Marnichs Cradle of Man isnt it. Instead, in a Tanzanian hotel, two American couples cross paths in a tiresome evening of Love Boat-style adultery. Is an intriguing science-versus-religion debate in store? Nope. Cradle of Man uses scientific metaphors to talk ponderously about love and infidelity. It is clunky, with lots of misspent and misconceived emotion that makes you lose faith in its navigation long before it ends. Dave Amber Through March 5. Florida Stage, 262 S.
