Early humans developed larger brains as they adapted to colder climates, according
to University at Albany researchers.

The study, to be published by Jessica Ash, a graduate student in psychology, and
professor of evolutionary psychology Gordon G. Gallup Jr. in the spring edition of
Human Nature (Vol. 18, Issue 2, 2007: Transaction Publishers), suggests that human
cranial capacity as an indicator of brain size grew dramatically during our
evolution, and that variations in global temperature as well as progressive shifts
toward global cooling account for as much as 50 percent of the variation in cranial
capacity. The research utilized several measures of paleotemperatures and a sample
of 109 fossilized hominid skulls collected over the past 2 million years.

In addition to the impact of global cooling, "By paying close attention to the
geographic origin of each of the fossilized skulls," said Gallup, "it became clear
that seasonal variation in climate may also have been an important selective force
behind the evolution of human cranial capacity. Specifically, we found that as the
distance from the equator increased, north or south, so did brain size."

The authors suggest that a key environmental trigger to the evolution of larger
brains was the need to devise ways to keep warm and manage the fluctuations in food
availability that resulted from cold weather.

In species other than humans, problems posed by cooler climates were solved by
adaptations such as hibernation and migration, and by metabolic adaptations including
fur and the development of fat deposits. During human evolution, however, the
authors
surmise that solutions to the problems of cold weather and a scarce food supply
featured detailed and progressively more refined cognitive and intellectual
strategies,
such as the development of cooperative hunting techniques and more sophisticated
tools
and weapons. Increased brain capacity also brought with it the use of fire as a means
to keep warm and cook, adaptations in clothing and shelter, and the development of
more
refined social skills.

I'm very suspicious of the speculations they attach to the brain size
increase suggesting it was "needed". It's at least equally likely to
have been an artifact of scaling - i.e. that the humans became larger
to retain heat better, & hence also had larger brains. That's if the
size increase happened at all, & wasn't just a misreading of available
data by the researchers, which happens all the time...

Mario's speculations about cliff-face-living
hominids (with constant immersion in the
sea for infants under about three) make
about as much sense.

The only difference is that he does not get
published. He should first acquire a degree
in Psychology -- then he could publish any
old crap.

Well, look at that, I am also the one who claims that our brain
enlarged when we came to live in colder conditions.

It's a nonsensical proposition unless you can describe why the same
didn't happen to the other species that lived alongside hominids in
these colder climates.

Obvious human evolution was a process in which human intellect was
greatly rewarded (yourself being one exception).

Well, other animals also, when they move to colder climate, adapt to
that colder climate. But, we are in a specific situation.

somewhere info about heat loss in humans, you'll find out that we don't lose
our heat through our body, but mainly through our head.

AAT is true, this isn't a surprise. Because when you are in water, your head
is outside, and your body is immersed in water. If we didn't have an
insulation of body, heat would be drained out of us. But for head we didn't
need so big insulation, because head isn't in water. Hence, we lose heat
through our head. But hey, we can put our head out in the cold, our nose can
freeze, our ears can freeze, our face can freeze, but our brain musn't
freeze, outherwise we will stop functioning. And brain has fat, anyway. So,
why don't put a little bit more fat? It is the easiest way. Also, IIRC the
bones of skull became thicker (but I am not sure at the moment). -- Mario

Delineate these specifics so that people don't think you are talking
