Having said that, it's impossible to know what he actually meant from the OP's description. For instance, I have heard many people say that survival-of-the-fittest evolution is not really working on people anymore because we are saving all of our old and sick, and mating with them based on whether they're nice rather than fit (or at least the criteria have changed). Furthermore, it seems that less successful/intelligent/rich people are getting less children than their less fortunate counterparts. Of course, that is still evolution (just in the wrong direction), but I can forgive a person for not knowing/understanding that.
.
idk about this, i still disagree with it time after time, especially after meeting some of the people i know.
Hell the most athletic person i have ever personally met/befriended in my life has the most average/below average parents who were never athletes in high school and were never smarter than your average joe, and hell he LOOKS like the most unathletic person ever also, but despite all that he destroys everyone in every single sport i have seen him play, even ping pong.
now I know that is just one person with one example, but i have fruitless amounts of others, and after seeing so many things opposite of what you just said with my own two eyes, its really hard to believe that "hot athletic guy + hot smart girl = hot super athletic smart child"
So are you saying that you don't believe in evolution (for humans)? Because I'm pretty sure that it has been proven that it does exist. Also, I bet that when you think about it, you will also see more positive than negative examples. For instance, most people look somewhat like at least one of their parents, and look similar to their siblings.
But some things are heritable while others aren't. And the outside world can affect different aspects of your character differently. Furthermore, a lot of randomness occurs in the evolutionary process. There are basically three main processes going on: selection, cross-over/combination, and mutation. Selection is about who gets to reproduce and with whom. In the paragraph you quoted I was mostly talking about that, because nowadays the weak are less likely to die and more likely to found a mate compared to the old days and other animals.
Then there is the way in which the parents' genes are combined to form the child's. Now, I have very little knowledge of what traits are and are not encoded in these genotypes, but I do know that the combination can be surprising. Here is a kind of contrived example, but I hope it gets the point across: let's say that both parents are not athletic because for both of them one leg is longer than the other. Let's also say that there is no "athleticness" gene, but there are "length of left leg" and "length of right leg" genes. If the child gets the "long left leg" gene from the father, and the "long right leg" gene from the mother, he will be much more athletic than either of them.
And finally there is random mutation, which could potentially let the child grow wings and make him super athletic (I guess). (It won't actually let him grow wings, because those mutations are generally a little smaller than that.)
However, the idea of evolution is of course that the odds of getting a child with beneficial traits are better when the parents have those traits as well, and that is also my experience. Most smart people I know have smart parents. Most fat people I know have fat parents. Most athletic people I know have parents who were athletic in their day or at least into sports. And of course, evolution will only alter your innate traits and the environment and situation in which you live and grow up will have great effects as well.
