Does media portrayal of specific individuals help change our culture's view of beauty and thus the way we choose partners and evolve? Is there no impact?

For example, skinny white people are in the media a lot, are they more appealing and thus more likely to make it through genepool selections?

Does the culture we live in determine our evolutionary path based on the morals, and qualities required for the time?

For instance, mental capacity is in the forefront nowadays, so will we choose to breed in smarter people because it's more culturally acceptable?

Since we have free will and are able to go into any corner of the planet to live, can we choose our evolutionary path based on where we choose to live for instance?

This is within reason, obviously we cannot live underwater on evolution alone. I'd really like to know perspectives on this one.

I've been told that human eyeballs don't grow, but that would mean that newborn babies have eyes that are the same size as a full grown adult.

Imagine we have a healthy, adult human on an operating table sedated just enough to nullify the pain, and surgeons set about removing the subject's internal organs one at a time with precise medical operation; how long could the subject survive (eg, be coherent, for example be able to talk or tap out signals with their fingers).

Surely the subject would only need a heart and lungs to do this, although as soon as they had to eat or drink they would die?

Silly question I know, but I have always wondered...I'm not very educated when it comes to Biology!

Thanks!

4.Why are there no root hairs on old sections of the root

5. Ehy do biologists associate downward material movement with xylem and upward with phloem.

6.Explain how vascular cambium produces more xylem each year and how it contributes to secondary development

when searching for the genetic basis of an illness, a good idea is to conduct a wide study of patients with that illness. How does one actually find a genetic marker, a gene with mutations that lead to a specific illness? What kind ofe xperimental design does that involve? (please be detailed)

For many Christians belief in creationism seems as important as belief in God. I'm amused at their false "proofs" against evolution. Most really believe these silly arguments because it's what they're taught, and they don't challenge their leaders.

A few:
>It's just a theory (so's number theory, so math isn't real?)
>If man evolved from monkeys (wrong) why are there still monkeys?
>No transitional forms or missing links (false, there are many)
>Carbon dating is grossly inaccurate (yet all real scientists trust it?)
>Evolution can't be proven (not if you reject evidence & logic, but yes it can, & has been)
>Evolution should still be ongoing (it is)
>Mathematical improbablity, thermodynamics, the "watch parts in a tumbler" argument (falsely assumes that specific animals were the "goal" of evolution)
>God (or Satan) planted fossels to trick us (why?)
>Man's made in God's image & God's not a monkey (just dumb)
>Evolution is a religion (nope!)

So what are your favorites?
