Whale song

Whale song. Waveform traces of a short burst of the sounds made by a humpback whale (Megaptera novaeangliae). These sounds are produced by moving air back and forth through body passages. Humpback whales, who are thought to have the longest and most varied songs of any species, produce sequences which in breeding season can last up to 15 minutes and then be repeated for hours. These songs have characteristics which enable them to be identifed as belonging to a particular group of whales from a particualr area. They are used for communication and in courtship. Only the males sing

X-ray of human and chimpanzee skulls

Primate skulls. X-ray of the skulls of a chimpanzee, Pan troglodytes, and human, Homo sapiens seen from the side. The chimpanzee's cranium (brain-case, upper left) is considerably smaller than that of the human. Both consist of many spongy bones fused at sutures. Chimpanzees have prominent brow ridges (upper left) above their eyes. The large mandible bone (lower jawbone, lower left) has powerful chewing muscles attached to it. Chimpanzees feed largely on fruit by grinding it down with their flat molar teeth. The human jaw (lower right) also houses numerous teeth. Both humans and chimpanzees evolved from a common primate ancestor
