If I lay at the beach for the next 30 years, and my kids do, and their's do, and so do their's, and then their's as well, will my families skin become imune to skin ailments, or will we just turn into prunes?

Lamarck was involved in the theory of adaptation, right? Do you support his views, with regards to my question?

Extend the scenerio to a large population and you're getting close. As for Lararkism it's generally disagreed with since it suggests inheritance of acquired characteristics. This would mean that if you go to the gym and lift weights, getting all buff, your offspring would pop out naturally muscular, that kind of thing.
You doing okay, bobo?

Bob, you need to get your head around the concept of natural selection, which is simple in principle but also requires an understanding that most individual living creatures that ever lived don't have descendents today.
In order for a particular genetic pattern to be "selected", many thousands of alternative patterns are "rejected". That is what drives evolution.
Lamark proposed an alternative theory of evolution to Darwin's. It is sometimes taught as a way of helping students work out why some theories work and why competing ones don't.

Prunes, sadly SB - if any survive. Exposure to either destructive conditions, or even ideas, don't necessarily produce adaptations/ rejections facilitating survival. Lamark got it wrong. Look at history, or Iraq. Even sceptical sun-loving Australians haven't developed genetic resistance to melanoma or the Neo-cons. Survival is largely an accident, I reckon! But great while it lasts. Ho hum. All the best.

If your entire family would do this, most of them would die of skin cancer (not trying to be rude, just stating facts). If you have a genetically more diverse group (not just you and your offspring) those with superior melanin production will have a better survival rate. Eventually, over MANY MANY MANY generations, these people will turn a nice brown color.

Lamarkism doesn't work. But if any of you survive and have offspring some of them might survive too. But they will still look like prunes.

Read about Lamarck.
