So according to this text animals(once thought of as dumb)can manipulate their hormonal reactions at will and change their color?Why cant humans do the same?I dont believe it.But maybe animals are not as stupid as we thought.
Humans cannot change color for the same reason we cannot fly, we are not built to do so.
How do you not believe that certain animals change color? Scientists have seen this happen. Unless you're saying you don't believe what those scientists have found is true, and I have to ask what your explanation for how this happens.
I guess in this case, for you at least, truth is stranger than fiction.
We should not have a society of humans that have so many similarities! We should all be completely different.
Well, that would go against evolution actually. If we have a trait that is beneficial, then that trait will increase overtime if the individuals who have that trait live long enough to reproduce. So, for example, thumbs are useful to humans. We use them on a regular basis and have aided us in our survival, so it makes sense that everyone in our species would have them.
Our noses are miraculously in the centre of our face. How did that evolve there? Our hears are on the side of our head. Our arms are equal length. Our bum is well positioned so we don't drop feces on ourselves.
All of these things happen because that is the best place to have those things. If our nose was on the palm of our hand, it would make grabbing things difficult. Also, since our brain interprets the senses that we obtain from our environment around us, it makes sense that the parts of the body that allow us to gather information from around us would be close to the brain. So, aside from sense of touch, almost all other parts of the body that involve the senses are close to the brain, because it needs that information to get an idea of what is going on around it. Speed is important, because sometimes life and death decisions have to be made in seconds so having all the necessary information to make it as quickly as possible is important.That way the information can get to the brain more quickly. Our ears are on either sides of our head in order to gain a better advantage in hearing. If both ears were on the same side of the head, the side without an ear would be more difficult to hear from. If our "bum" was placed anywhere else it would more than likely be disastrous, since many diseases are spread through feces.
