Channels discriminate between solutes mainly on the basis of size and electric charge.
Explanation:
This was Lamarck's idea. Here's an example: Suppose giraffes originally had short necks that they stretched to reach high-up leaves in the trees. This continuous stretching of the neck was passed onto offspring, who as a result had slightly longer necks. This continued for multiple generations until we get today's long-necked giraffe. Lamarck was on to something (that something being evolution by natural selection, which Darwin discovered), but his theory wasn't completely correct since organisms can only pass on genes (segments of DNA that code for a characteristic or function) to their offspring. Since "stretching" would not code into DNA, it wouldn't be passed onto offspring, proving Lamarck's theory incorrect.

GMOs have a ton of pros and cons, so it's hard to say. Although, I personally would like to avoid them. With the amount of people who have gone gluten free, there's more of a reason for it than being a hipster or a yuppie. Because the demand for wheat is so high, we had to genetically modify it. Although this increased its abundance, a lot of humans' digestive systems haven't evolved with it. That is the reason why it makes so many people sick, because they cant digest it. If the rate at which GMOs are being created and nourished continues, it's likely our digestive systems will reject it, possibly causing famine due to the inability to eat our own food.<span />
