Biology Riddles

But I don't know if it's a matter of convergent evolution or just plain genetic relation with other invertebrates, so I didn't really get that right...

The girl of your dreams has told you that she thinks she wants to end her torrid, passionate relationship with you. You beg and plead with her, but she remains ambivalent. She finally agrees to abide by the results of an endeavour that you, at your wit's end, suggest. You say that you will pull the petals off of a daisy flower, one petal at a time. With each petal you pull off you say, alternately, "she loves me" or "she loves me not". What will be the outcome? Is it chance? To guarantee a positive outcome for yourself, should you begin with "she loves me", or "she loves me not" ? Will it make any difference with which phrase you begin?

 

Please read rules everyone, this is a mess!

 

Re: here's another

I'd say barnacles, though I'm not sure. They're arthropods but they look like mollusks.

Nope.

 

is there any evidence that penguins can't cross the warm waters of the equator?

Wales seem to have no problem with it.

 

it is a chaotic system analogous to many biological systems.

 

It is strange.
Even if none of the current penguins could handle the heat at the equator you would think that a penguin family would have branched off and adapted to it at some stage in history. Unless penguins haven't been around for long, but there are so many types so I imagine they have been.
Weird.
I think its some kind of anti-penguin conspiracy

apparently whales don't do it because migratory patterns are opposite on either side of the equator (i.e. summer migration in the northern hemisphere means winter migration in the southern hemisphere, while northern migration is bringing whales to the north pole, southern migration is bringing them to the equator)

 

ok then...but whales are not limited to either north of south, which suggests that they crossed the equator at one point in time

 

riddle

why don't we humans have a thick coat of fur?

 

Because we became semi aquatic before the ice-age when much of africa was flooded. Short coats helped us cross rivers and also find food such as crayfish and freshwater clam things.
We weren't forced to grow back coats during the ice-age because we figured out how to make clothing out of the furs and skins of dead animals.

 

no wrong

the answer

 

Or was it the loss of our fur that allowed for giant brains?
eh?

Surgically reduced their brain size? You gotta be kidding me.

 

don't worry about it, they were only students. Plenty around where they came from.
