maybe they can discern genealogy of the first tribe that that could communicate in writing??? end of post, the rest is my prescription speaking at 5 am.

somehow got me thinking if some symbols might be the sounds they, and we, make in 1 syllable. how many? what symbols? where? when?

the first symbol of the first alphabet, if i were to guess, looks like a stylized bird. it represents danger. maybe a part of the cave to avoid? there must be archives of photographs?

the first word? in proto indo european they say "ma" momma or mom mammy or mammary? but the first word the first syllable the first letter said by lucy when her child played too near the great rift was probably "Aaaaaaaa."

thats right , just like your teacher in kindergarten taught. A . that , pointed upward , is the beak of a bird. a bird who might sound an alarm if humans are about. a sound of alarm that makes a child instinctively stop. halt or Alto lest she disturb the birds .

i wonder what birds? gulls i'd think, as any sailor would. but crows or mockingbirds?
crows probably have been studied in some detail....

maybe ducks. or chickens. maybe even emu or dodos.

in hieroglyphic A is said to be a bull, horns down. the bull is named Apis.

something to look up tomorrow. bird calls.

spoiler. it is 110 hz. the musical note "A" so what bird?

a bird of the rift valley. ethiopia. tankanyika. a bird of 1/2 million years ago.

any cave art from homo nalidi. south africa?

there is an A at 55 hz, but this octave seems low for human women/children

a baritone is 110 hz at the low end. bass bottoms out at 82 hz. i wonder if the great opera basses go lower? could that be like a contrabass or something?

did i just notice that our electrical grid is tuned to A?

basso profundo begins at 82.5 hz . C i think. but ostrich, the most dangerous bird to australopithecines, might be out of vocal range?

maybe language was used searching for prey rather than avoiding predatory danger. the nile crocodile . definitely low.

ok found the charts of voice frequencies and a start on birds.

a coaches whistle/police whistle would be 2300-5k hz. i knew that was high.

but give me a break, coach, an electronic whistle?
