Obviously not a paddle, fin or flipper.
Sigh. Grow up, kudu runner. Nobody says humans can't grasp:
how do you open your oyster, my little boy?

The claim is that the Chimp hand has evolved further away from the
LCA than the human hand. Which means that whatever selective
pressures were on the human hand (Aquatic Ape), they were present
prior to divergence.
Our hand is more "Primitive," so to speak.
It's another example of how "Humans are apes" and "Humans evolved
from apes" has poisoned thinking. People look at Chimps and
Gorillas and assume that's what our ancestors had to look like. But, in
truth it's not even what their ancestors looked like.

The modern Hs hand is an intriguing mix of primitive morphology & derived function.
Traditionally, its form & function are explained as a functional �trade-off� between the requirements of locomotion & manipulation,
but recently acquired comparative, experimental & fossil evidence suggests: >this functional trade-off is more complex than conventional wisdom suggests. >When studying hand evolution within the hominin clade, the only morphological evidence comes from the hard-tissues,
evidence about hand function must be inferred indirectly from the archaeological record.
We lack information about critical aspects of hand form (e.g. soft tissues) & function (e.g. neurology) & non-lithic evidence about behavior:
comparative anatomical, experimental & ethological studies of modern Hs & other primates are critical to making more informed inferences about hand use in the past.
We review the relevant fossil & archaeological evidence within the relevant comparative context (other extant apes & dexterous monkeys),
we attempt to reconstruct hand evolution within the hominin clade.
We conclude by summarizing our current understanding (or lack thereof) of the evolutionary history of the modern human hand.

Do you think Homo erectus had a professional quality oyster knife?

If you really think that nobody ate an oyster before there were
"Professional quality oyster knives," or knives for that matter, then
hang it up. Unsubscribe. Shut off your computer. Give up.
You clearly have zero interest in these topics. You're reacting
emotionally, not engaging in any kind of rational discussion.

Yes, thes fanatics are dogmatically convinced they *know* the Truth:
human ancestors left the forests for the African savannas,
and the savannas made them naked, sweaty & bipedal:
"everybody" knows that...
