Jeаn-Bаptiste Lаmarck was an early evоlutiоnist. He saw humans as the ultimate prоduct of a goal-oriented evolution--that organisms gradually evolve into complex forms as the result of an innate desire to strive for complexity and perfection. The mechanism he supported was called inheritance of acquired characteristics. He believed that evolution occurred as organisms used body parts in ways that physically changed them, then those body parts were inherited by offspring. Which of these examples counters Lamarck's idea?
