The one that acts as a wing is a fairly recent invention I think.

Are you thinking of rigid sails?
Even a square rig can go up wind.
Boats have been going upwind for a few thousand years. If a boat can sail upwind its using lift to do so.

I'm pretty sure you can do that with a flat piece of plywood on roller skates. You don't need to invoke an aeronautical wing to explain is.

The general idea is that humans had a common ancestor before that ancestor was human. Modern man is about 200,000 years old. The ancestors prior to that might well have travelled all over Asia, Africa and Europe and developed their modern man features that included different racial characteristics. Different climates and diets would have accounted for these different characteristics.

It that case it's the curved surface - the same as a sail that
allows a ship or yacht to sail into the wind.
It acts like a wing.

It's still the same physics. Creating low pressure/high pressure system where the object/boat is is pulled into the low pressure.

No, The difference is that the white races moved and lived in the north for long enough that there was a pigment change. There is no argument for a biological superiority based on colour either way. The difference was driven by environment not biology or development. It is the same race developed at the same time. We were likely all darker in the beginning, I don't know what shade.

Whiteness may be a darwinian effect.

Ummm - you could probably argue that the Chinese are the furthest from the apes.
They seem to do better at Universities on average compared with everyone else.

No all the same

Ya canna Han a man a grander spanner than a drive to education. Their kids are not allowed to fail whereas ours are told it doesn't matter, you're just as good and anyway Math is a racist social construct.

When I was at Uni the Chinese students were getting obviously much higher grades
and that was despite their language handicap. Embarrassed

"Give me a child until he is 7 and I will show you the man." -- Whoever said it...

Intensive rote learning doesn't help a 7yo much but when his/her knowledge base grows, there is ingrained info ready to be accessed. We gave up on that I think back in the '70s and then there was the change in the early '80s to help advance females in the math/science type subjects, ultimately only achieving that goal by bringing boys grades down.

They value education.

Africans, Aborigines, Islanders who value education and apply themselves would be as 'smart'.

East Asians, Indians or Europeans who do not value education are as thick as mince - look at John Smiff or Arrsie or greatdividedparrot or ravin' ducky.

Some old Greek guy called Aristotle who realised that the 1st 7 years of a child’s life represented a crucial formative stage of development. And of course ... he was right.

The Australian aborigines invented the returning
boomerang, or rotating wing, 50,000 years ago.

Such a command of complex aerodynamics and
physics certainly puts the numerous racists here
on the back foot.

What a load of utter garbage.

My 6 year old can make awesome paper aeroplanes.
Do you think he has a complex command of aerodynamics and
physics?

He is constructing what you showed him, 50,000 years ago he didn't even have paper. At that point your forbearers may have resembled a cockroach if this evolution theory is correct. It would make sense.

They worked out shaving different surfaces on a stick caused lift.
Do you really think that equals a complex command of aerodynamics and physics?

The first step that everyone else has built on.

You're an idiot of the first order.
There's a direct line from kites and sails to aeronautical wings.
Ever sailed? A sail is exactly the same as an aeronautical wing, in use for at least 5 thousand years before a boomerang was sighted.

You should probably stick with unsupported insults as it looks more stupid than normal when you show that you don't know what you are talking about.

The theory between flight and sail does use the same theory but the bent surface aspect that is common to both flight and boomerangs is not used in sailing.

The bent sail and spinnaker are used downwind not using the air travel principal across a dissimilar length path just the following wind. Sailing up wind uses a tight flat sail. Up wind while using the same principal relies on a completely different mechanism, the movable angle of the sail not the shape of a fixed wing.
