Vee-ahvi teooria

Olin varem Buckminster Fulleri kaudu kuulnud teooriast, et inimesed pärinevad veest. Nüüd nägin TEDis ühe selle teooria põhilise levitaja ettekannet - Elaine Morgan says we evolved from aquatic apes. Mulle, kui suurele veesõbrale, meeldib see teooria väga :)

Aquatic ape hypothesis

The aquatic ape hypothesis (AAH), sometimes referred to as the aquatic ape theory, attempts to explain some unique characteristics of humans through a period of time spent evolving in an aquatic environment. These characteristics include subcutaneous fat, hairlessness and bipedalism. The hypothesis was first published with an evolutionary explanation by Max Westenhöfer in 1942. The hypothesis was proposed again in 1960 by a marine biologist, Sir Alister Hardy, and subsequently promoted by the writer Elaine Morgan.

Though the theory has become widely known, it has been criticised by the scientific community for a variety of reasons, including susceptibility to parasites found in water, a lack of innate swimming reflex or adaptations, the characteristics of human subcutaneous fat, the failure of the fossil record to support the idea and human's inability to cope with water-dwelling predators. However, there has been some supporting publications in scientific journals and some support within paleoanthropology, at least for a weak version that doesn't accept there was an actual "aquatic ape".

As compared to the great apes, their nearest living relatives, humans exhibit many significant differences in anatomy and physiology, including bipedalism,[1] almost hairless skin like some marine mammals,[2] hair growth patterns following water flow-lines,[3] increased subcutaneous fat for insulation,[4][5] descended larynx,[3][6] vestigial webbing between the fingers,[7] vernix caseosa,[3] a hooded nose, muscular nostril aperture control and the philtrum preventing water from entering the nostrils,[3] voluntary breath control like marine mammals and birds,[3] and greasy skin with an abundance of sebaceous glands, which can be interpreted as a waterproofing device.[8] It has also been suggested that the abundance of docosahexaenoic acid and iodine in seafood would have been helpful in the development of a large brain.[9]




Illustratsioon on sama tädi tehtud. Juhin eraldi tähelepanu vaalade evolutsioonile - kunagi olid nad nö. ürghundid mere kaldal.

Mulle on alati tundunud, et eestlane arnes välja hoopis karust.

Kellest Sina evuleerisid?
