I hope you have read more about this than I have

Does the argument of age diminish truth? Or are you saying
just because Ramachandran got his initial idea from the inside
of a Bazooka Bubblegum wrapper that it lacks validity?

Ergo we might conclude that being mute and slow to move would
be viable traits for all successful hunters ..... hmm...
"The silent means of communication afforded by the use of
gesture was particularly useful to warriors in combat, who
were able to give signs to each other over a considerable
distance in order to surprise the enemy."
"A system of intertribal communication through the use of
ideographic gestures made with the hands, sign language was
first noted by explorers as early as 1535."

What I have noticed about this NG is some contributors use
sarcasm as a form of argument. Although it does suggest some
cleverness on the part of the "sarco-vocateur," like those who
have perfected card tricks to dazzle their guests ...it is not
a valid way to dispute another person's hypotheses.

But convictions are not always habit forming. Does he

Well ... yes ... I suppose that would make for more
