Believe it or not, scientists study fruit flies to learn more about how humans think.

This is a very interesting artice. I think it is really cool that they can test fruit flies to figure out some human behavior. It's cool that certian types of fruit flies can go without sleep because of a change in their genes. It's interesting that when certain flies didn't get enough sleep and weren't allowed to eat for twelve hours, their memory improved. This shows the importance of sleep.

It says that they did the experiments on fruit flies which have only half the amount of genes as humans. It is a big difference so I doubt that tests on fruit flies could compare to what happens with humans.

Fruit flies survive because of their large numbers. When there’s a a lot of food, the rovers have the advantage because they don’t need as much sleep. When there’s not enough food, the sitters have the advantage, while the rovers die off. This way the two groups don’t have to compete for a small food supply, and their species can survive. How does this experiment apply to humans? Are humans rovers or sitters?

I think most people don’t get enough sleep. We can function with less sleep, but when we’re stressed out or have to perform complicated tasks, like math or driving, we aren’t able to function as well.
