How did eyebrows evolve and what will they look like in a million years?

Answer 1

Eyebrows have evolved as being important in the non-verbal communication process to each other. In a million years, the communication of eyebrows will hopefully be understood better, and convey non-verbal thoughts far more expressive than we could possibly fathom now. Here is an example of how eyebrows have evolved in just the past couple of decades.

Also, eyebrows are tweeked into shapes, usually arches. The arch has gotten higher over time. I suspect that the arch is here to stay, but there may be times when a wavy, swoop, or even some fancy design will become popular.

I also think that you would enjoy this FACS program that helps one decode facial actions.

I bet you are also wondering why we even have eyebrows. Well, I've got the link for that as well!

Answer 3

This is the stupidest question, ever!

Answer 4

The problem with looking at a human body now and asking the "how" of evolution is that we tend to like "structural" answers. eyebrows are above the eyes therefore they must protect the eyes - this is a logical error called "post hoc ergo propter hoc," (after this, therefore because of this.) Eyebrows do not stop sweat from reaching the eyes, if they did there would be no sweat band industry. Or, if that is the evolutionary purpose of eyebrows, why don't horses (who sweat heavily) have heavier eyebrows than humans? Not all adaptations have a mechanical purpose. Some scientist theorize that eyebrows developed and remained part of mammal evolution (many other species have eyebrows too,) for the purpose of face cognition and emotional communication (if you want to read a typicl paper on the subject try this one: http://www.psych.ubc.ca/~schaller/Schall... (but it is a little long and technical.)
The ability to recognize individuals by their face develops within 2 months of baby's birth. This skill must have been very important when human beings lived in large related groups. If hits is why "eyebrows" were selected within the evolutionary process, we would expect them to remain and not change over the next 100,000s of years (after all we still have an appendix after all of our specie's evolution.) But in the end, there is no way to say either how eyebrows developed or whether they will remain or how they may change. Evolution is a process. However, if you are interested in the theory of facial perception, try this site as an intro: http://en.wikipedia.org/wiki/Face_percep...

Answer 5

I believe back in the day, they may have been good for protecting the eyes from sun, and dust..they were a lot bushier and served the purpose that sunglasses do for us today.
In a million years mankind will probably be hairless everywhere.

Answer 6

This has to be hands down the most irrelevant question in the entire history of humanity.

Answer 7

Human Beings did NOT evolve from apes. To evolve means to drastically change, because the environment no longer supports a present condition... If human beings evolved from apes the ape would NO LONGER EXIST... The human Being would have taken it's place in the environment...

As for the eyebrow question, God gave us eyebrows to protect our eyes not only from sweat from our brow, but to help protect our eyes from direct sunlight, and UV rays... What will they look like in the future... The same as they do now... depending on your ethnicity.. to make my point look at photos of your grandparents when they were younger, then look at your own..

Answer 8

maybe thicker than we have right now... i

Answer 9

i think they will look the same

Answer 10

In a million years we may not even have eyebrows. Perhaps we won't have eyes, our minds will have developed so much that we can see with just our mental capabilities. They started as a tool to keep sweat out of our eyes, then they became a fashion statement, so much so that some women actually had them tattooed on, next it would seem they would be useless and the body would no longer grow eyebrows.

Answer 11

i doubt we'll evolve at all at this point considering we solve every need we have with technology, our body wouldn't see a reason to evolve
