The narwhal was scientifically described by Carl Linnaeus in his 1758 publication Systema Naturae. [5] The word "narwhal" comes from the Old Norse nárhval, meaning 'corpse-whale', which possibly refers to the animal's grey, mottled skin and its habit of remaining motionless when at the water's surface, a behaviour known as "logging" that usually happens in the summer.
Since modern human/Neanderthal admixture is known to have occurred in the Middle East, and no modern body louse species descends from their Neanderthal counterparts (body lice only inhabit clothed individuals), it is possible Neanderthals (and/or modern humans) in hotter climates did not wear clothes, or Neanderthal lice were highly specialised.
Modern human brain size seems to have decreased since the Upper Palaeolithic, with a sample of 28 modern human specimens from 190,000 to 25,000 years ago averaging about 1,478 cm 3 (90.2 cu in) disregarding sex. [14] The largest Neanderthal brain, Amud 1, was calculated to be 1,736 cm 3 (105.9 cu in), one of the largest ever recorded in humans ...
As more fossils were discovered through the early 20th century, Neanderthals became characterised most especially by Marcellin Boule as a unique species of underdeveloped human. By the mid-20th century, human evolution was described as progressing from an apelike ancestor, through a "Neanderthal phase", ending in modern humans.
Belugas can be found in the far north of the Atlantic and Pacific Oceans; the distribution of narwhals is restricted to the Arctic and Atlantic Oceans. Monodontids have a wide-ranging carnivorous diet, feeding on fish, molluscs, and small crustaceans. They have reduced teeth, with the beluga having numerous simple teeth, and the narwhal having ...
African elephants call each other and respond to individual names — something that few wild animals do, according to new research published Monday. Scientists believe that animals with complex ...
Sperm whales have the largest brain mass of any animal on earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males, in comparison to the average human brain which averages 1,450 cm 3 (88 in 3) in mature males. [44] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [45]
