As is now fairly well known, tropical frogs are being devastated by the chytrid fungus. The Gamboa Reserve has an enclosed area where many poison dart frogs roam. (They are fed, so are probably no longer poisonous.) They are highly variable in their patterns. Here we have two versions of the green-and-black poison dart frog (Dendrobates auratus).
Also here are two individuals of the strawberry poison-dart frog (Oophaga pumilio). These are examples of the variety called the “blue jeans morph”
On May 25, 1925, John T. Scopes was indicted in Dayton, Tennessee for violating Tennessee’s Butler Act that prohibited the teaching of human evolution. (Most people think the law forbade the teaching of any evolution, but that is not the case.) After a weeklong trial, Scopes was convicted on July 21 after the jury deliberated for nine minutes, but the conviction was set aside on appeal because of a technicality: the fine, $100, was levied by the judge, and fines over $50 were supposed to be decided by the jury. Above is Scopes one month before the trial.
