morphological change within a species can be profound. horses are the examples usually used to teach kids. but you need only look to dogs. the strcutural difference between a pekinese and a mastiff is fairly extreme. new species can emerge in as little as 8 generations with fruit fly for example but the differences will not always be visible, so the morphological change can be miniscule. so you can have extreme morphological change and remain within the same species, and subtle change and become a new species.

sorry not to be useless.

while we are on the subject of horses...

Although the Przewalski's horse has 66 chromosomes, compared to 64 in a domestic horse, the Przewalski's horse and the domestic horse are the only equids that cross-breed and produce fertile offspring, possessing 65 chromosomes.

Dogs get acne.

Cashews are related to poison ivy. The bulk of the cashew plants toxins, urushiols, are concentrated in a layer within the cashew nut shells. That's why you cashews are not sold in shell.

Dont Arabs have an odd number of chromosomes too? I know they have an odd number of ribs...

Aulophobia is the fear of flutes

Tipping in restaurants in Iceland is considered insulting

Chocolate can make frogs sexually aroused

If humans could run as fast as a cockroach, we'd reach speeds of more than 300 m.p.h

One side of the Nobel Peace Prize medal depicts three naked men frolicking

Cockroaches run at 300 mph?

If you swallow a jamjar's worth of apple pips you will die of cyanide poisoning.
(Swallowing a jamjar full of apple pips is very difficult.)

You mean the horses, not the people, right?
I was confused for a minute, until I checked on Google and all related site were mentionning horses.

Yes, sorry... slight lapse in clarity and context! lol... Less vertebrae and ribs in arab horses than in any other breed.

Why didn't I even think about Arabian horses? I was going to comment. I'm so glad I waited.

Bats always turn left when exiting a cave.

Right handed visitors to an exhibition usually turn left upon entering the hall.

Thanks for the explanation.

Meanwhile, I finished my Chemistry class this morning, and now I'm going to play a game.

It is estimated that there are more than 169,518,829,100,544,000,000,000,000,000 ways to play the opening moves in chess. 169,518,829,100,544,000,000,000,000,000 and 1 if you resign on your first move.

What about giving the chess board a good fling across the room? 169,518,829,100,544,000,000,000,000,002, then.

How many moves are counted as the 'opening moves'? White plays first and can make one of twenty moves; black, regardless of white's move, can follow with one of twenty moves. That's four hundred possibilities, and I can appreciate the escalation, but opening moves?

It is estimated that there is an infinite number of ways to play the opening move in 'Mornington Crescent'

'Barbecue' is the only word in English deriving from the Carib language.

So our word for the inland sea bordered by the south-eastern USA, Mexico, central America, Venezuala and Guiana, in which may be found islands such as Jamaica, Cuba, Haiti and the Bahamas, does not derive from the Carib(bean) language, then?

Inland Sea? Where?

Yes, I'm sure that their name derives from their language too. So maybe it should be non-proper nouns etc.
