many of the morphological difference between humanity and the great apes are easily accounted for via the aquatic ape/ waterside ape hypothesis
that in the area where lucy and some other skeletons (north eastern africa) have been found has been known to have flooded multiple times over millions of years and Oldowan flint tools dating as far back as 2.5 million years found on Socotra Island off the tip of the horn of africa (north eastern africa).......which fits perfectly with EU solar cycles = change in solar output during orbit of galactic core/ moving through galactic circuit..... causing ice ages = drying up and melts causing flooding/ rises in sea level which created swampy areas , rivers, lakes, small isolated islands (touches on Buckminster Fuller idea that humanity evolved intelligence on an island away from large predators),etc...
the constant inundation and drying up was the selective pressures (thanx to Electric sun = variable output sun as it moves through galactic circuit/ around galactic core) for traits that were advantageous to a semi-aquatic life
-loss of body fur
- keeping hair on heads for hand holds for babies in a water environment
-more stream lined and straighter legs when water receded would lead to bipedalism on land
- subcutaneous fat 10% more & placement in line w aquatic mammals as vs land mammals w less fat layers and majority around organs not under skin like blubber that makes it easier to float and out babies are born way fatter than land only mammal babies while also showing signs of not being afraid of water when born as well as basic swimming technique that is less vulnerable and less helpless than if we were land based only...human babies are born on land as the most helpless animal known
- elongated and downward pointing nose (deformity that proved via natural selection to be beneficial )better at preventing water entering the nose while diving
- well developed diving reflex with slowing down of heart and lung rate just like other diving animals = aquatic mammals and diving birds like ducks
- descended larynx which allows control of breath (for diving/ swimming) enables talking which we share only with other aquatic mammals ....orangutans, chimps, and gorillas all have the brain areas related to controlling breath and speech, but do not have descended larynxs to actually control breath which is required for speech
- expanded well devolved cranial sinuses which would help keep heads above water
- lack of twitch muscle like land based only mammals due to being in and out of water for long periods and multiple time periods in a watery environment
- lack of panting to cool off unlike all other land only mammals
-watery ecosystems (especially estuaries where fresh water meets salty ocean water) are some of the most abundant in life = food resources that are easily gatherable as vs the harder and more time consuming and vulnerable hunter on the savannah theory
- water way food sources higher in known brain building nutrients like zinc, omega 3 fatty acids, DHA, folic acid etc etc
- easily gathering food is a quicker promoter of social behavior and cohesion/ working together/ culture as vs open savannah
-safety of being able to flee into the water from land based predators and vise verse onto land to get away from water predators...back and forth as vs open savannah only theory
- a hymen (though chimps do posses a hymen but chimps are themselves separated from larger ape populations and each other = general chimp and bonobos by rivers and lakes)
etc etc etc
The biggest proponent of aquatic ape/ waterside ape theory recently passed away july 12 2013, Elaine Morgan. She became interested in it due to feelings of open savannah theory couldn't explain our differences from other great apes and was too sexist male hunter relegating females to hiding in some cave as vs mutual sexes working and living together gathering easily obtainable food in and around water....she came across a marine biologists Alister Hardy mentioning our subcutaneous fat most resembled aquatic mammals as vs land only mammals
