What Is Dialectical Behavior Therapy Used For? It was originally intended for people with borderline personality disorder, but has since been adapted for other conditions where the patient exhibits self-destructive behavior, such as eating disorders and substance abuse.
Jean Baptiste Lamarck (1744-1829) is one of the best-known early evolutionists. Unlike Darwin, Lamarck believed that living things evolved in a continuously upward direction, from dead matter, through simple to more complex forms, toward human perfection.. Species didn't die out in extinctions, Lamarck claimed. Instead, they changed into other species.
We now know that this is incorrect, but let's examine what Lamarck meant by 'acquired characteristics.' Lamarck's theory stated that evolution worked on individuals, like Ms. Intergalactic. He postulated that any change to an individual during its lifetime would be passed directly to its offspring. So if mom has big muscles, then baby has big muscles. His classic example involved the necks of giraffes. Lamarck observed that giraffes have disproportionately long necks.
