>Is there any scientific evidence
No, the archaeologists merely had too much to drink at a conference one night
and decided to concoct a story about archaic humans and the mammoth.
>I find it implausible
... therefore it couldn't possibly be supported by evidence, right?

It means a future of morbid obesity.

At roughly 45-minute intervals, I push away from my desk to get a drink of water or a cup of tea;
and before I sit back down, I grab my dumbbell for some lifts, or do Sumo squats, or Sumo push
against a wall. I also look outside, it's good for the eyes to focus at a distance occasionally.

It sounds like you may be wanting Quantum Chemistry; but that topic
is a very deep rabbit-hole, the bottom of which no one has yet got to.

I looked at the Wikipedia article on Coniine and was struck by two things:
(1) the low molar mass of 127
(2) the statement "it has been synthesized by man"
L0L until I choked ... by *what else* could it have been synthesised? Ants? Aliens?

eyeballing the graph, it looks like an increase of 8.0Mbpd between Q1 2013 and Q1 2018
so the rate of increase is 8.0/5 = 1.6Mbpd per year, and at this rate, consumption will double in 60 years.

a period after a mathematical symbol or expression looks retarded

Marilyn vos Savant caught a lot of grief for her (correct, but poorly-written) first answer, but her subsequent two replies give fuller explanations.

I've been looking at this function as an alternative
to the logistic function, but I don't know its name.
Any help appreciated, thanks.

Grading "on the curve" assumes that class performance will be
distributed as a bell-curve. Is there any basis in fact for that assumption?

From the abstract (link below):
>>a possible remnant of the metopic suture is observed
...so the "persistent metopic suture" hypothesis (Falk, 2012) is largely unsupported
by this specimen. Since the metopic suture fuses in humans at age six months
(± three months) we would not expect to see it in this three year-old specimen anyway.

>Is this correct?
Uhh...No. There are relatively few T-Rex fossils, compared to many more hominin fossils,
and no one (except for the occasional lunatic) disputes the "quality" of those specimens
as "direct evidence" for existence. Dimissing "inference" as a legitimate scientific process
is an even-worse departure from sanity, and indicates a severe lack of knowledge.
