Let's say we do not merge with cybernetics and continue being biological, also without any gene manipulation, what are we possibly changing into? Let us start with some obvious things that we know is happening.
>We are losing more and more hair, it is likely that future descendants will be hairless, at least on most of the body.
>Our wisdom teethe are being phased out, not being needed due to softer cooked meats, our jaws may also become smaller.
>Pinky toes will slowly disappear, not being needed anymore.
>The appendix will most likely go away sometime down the line.
>These is some evidence that we are developing a new blood vessels in our wrist/arm area.
>Our brains are becoming bigger or smaller depending on who you ask, not smaller as in dumber, but just more efficient, more condensed you could say.
>With each generation we are becoming taller, at least in developed civilisations due to all the food we now have.
>There is also some speculation that we are developing some sort of telekinetic ability, not as in being able to control things with the mind, but rather being able to communicate with and read minds.
>Our fingers could possibly become longer due to our interactions with computers on a daily biases.
>We may develop less muscle as machines do all the heavy work.
Basically we are becoming greys.
Any other speculations?
