Veoma zanimljiva teorija o tome da je čovek zapravo polu-vodozemac ...
Osnovna teorija je govorila o tome da smo sišli sa drveta u potrazi za hranom, a uspravili se na dve noge zbog visokog rastinja u savani (to je bilo lakše nego evoluirati u višeg četvoronošca?) .... Nova istraživanja kažu da svi majmuni hodaju na dve noge u vodi ... i da smo zapravo tako ostali uspravni ...
A tu je i činjenica da svi sisari koji nisu dlakavi imaju vodene bliske pretke (uključujući slonove i nosoroge!) .... postoji samo neki pacov koji je potpuno bez dlake ... ali on živi isključivo u zemlji i ne izlazi na površinu nikad, pa mu je dlaka nepotrebna ...
Dakle, evo dokaza:
The aquatic ape hypothesis puts forward these main arguments:
Nakedness: Of the hundreds of primate species, humans are the only species in which hair does not cover almost the entire body. The only environments known to give rise to naked mammals are aquatic and subterranean. Other naked mammals are totally subterranean ( naked mole rat), swim ( whale, dolphin, walrus and manatee), wallow ( hippopotamus, pig and tapir) or seek mud and water regularly ( rhinoceros and elephant).
Bipedalism: Humans are the only surviving bipedal mammal. Although it gives us the ability to use tools whilst walking or running, it directly causes the following problems: back problems, knee problems, varicose veins, hemorrhoids, hernias and problems with childbirth.
Since evolution works in small steps, it is hard to see how bipedalism could have evolved on the savanna: the mass of the torso makes bipedalism inherently unstable and inefficient. Bipedalism is not observed in other savanna animals. Water, however, supports the body, and non-human primates such as bonobos and proboscis monkeys have been observed wading bipedally in their occasionally flooded habitats.
Breathing: With the exception of humans and a few other outstanding animals (many of which had aquatic ancestry like the elephant), land mammals have no conscious control over their breathing. The voluntary control humans have over their respiratory system is similar to that of aquatic mammals which inhale as much air as they need for a dive, then return to the surface for air.
Fat: Humans have ten times as much fat in our bodies as is normal in an animal of our size. We are by far the fattest primates. Mammals which hibernate have seasonal fat: aquatic mammals, like humans, retain fat throughout the year.
Childbirth: Dramatic increase in the size of the cranium is a prominent theme in human evolution, making childbirth difficult and dangerous. Water birthing is known to facilitate childbirth and to reduce risks to mother and infant. Human infants are born covered in vernix caseosa, a waterproof coating, and continue to draw oxygen through the umbilical cord while underwater.
Nutrition: Human brain tissue requires comparatively large amounts of omega-3 fatty acids, which are uncommon in the land food chain but prevalent in the marine food chain.
Tears and excessive sweating, prevalent in humans but not in other primates, are considered further evidence to support the hypothesis, insofar as they are vectors for the removal of excess salts from the body, as might result from the ingestion of saltwater. Other marine animals, such as the marine turtle , secrete tears for this purpose, although these tears are of higher salinity than human tears.
Supporters of the hypothesis also mention the webbing between the human thumb and fore finger, which has no apparent value on land.
Odjednom Šijamalanova Lady in the Water ne izgleda tako naučno-fantastično. Samo još neko da mi objasni zašto mi se koža smežura uvek kada se tuširam i pristajem da budem vodozemac
