Lamarck's proposal of evolution - 1. Originally, giraffes had short necks. 2. Giraffes stretched their necks in order to reach food. 3. With continual stretching, most giraffes now have long necks. Darwin's proposal of evolution - 1. Originally, giraffe neck length varied. 2. Struggle to exist causes long-necked giraffes to have the most offspring. 3. Due to natural selection, giraffes now have long necks. Darwin completed a five-year journey around the world on what? And what did he...
