So I'm in 9th grade and I was in biology class today and we're talking about evolution. And today I was reading about Vestigial structures and how eventually they disappear in further versions of organisms. I'm worried because in humans, a lot of people aren't using their pineal gland and I was wondering, what if that disappeared completely in humans in the future? Is that what the Xians are striving for? I don't know just some free thinking, give me your ideas about it.
