In Search of Life

Episode xx: In search of life,

"We have evolved, like everything else, and we are constantly evolving. The force of selection is still working on us, but much slower than forces of our social life. Now do you want to be part of this constantly evolving, constantly changing life?" The man said. He looked at the girl sitting on the side of the room. She was beautiful. She had yellow hair.
Silence filled the room. No one said anything, no one even moved. The man continued, "Am I that boring? the answer is that we don't have a choice. Like it or not we will all contribute to the evolution of our species. Some of you might have a few children, contributing to the gene pool. Even our so called altruistic behaviour is part of our selection force. Self sacrificial genes cannot be favoured, but self sacrificial individuals are favoured in most societies. If you are not contributing to the gene pool, or you are not helping anyone, why do you live? Why don't you kill yourself?"
Silence was still there. No one moved. The man looked at his watch and said, "Thank you all for listening. I hope you found this intellectually satisfying. If you have any questions I'll be around for a few minutes."
Everyone started to leave. Three students came to the man, a white girl with red hair, tall, and skinny, a half black, very muscular boy, and the blond girl. The first one was the red head girl, she asked, "I have a question what do mean by self sacrificial individuals are favoured, but self sacrificial gene cannot be favoured."
The man said with a smile, "That's the notion of selfish gene. The basic natural selection is maximizing survivability and reproduction. The altruistic behaviours were first seen as an unexplainable phenomena. But as soon as we realized genes were involved we saw that individuals who sacrifice themselves for the sake of their genes are common. "I would happily give my life for 2 siblings, 4 grandchildren, or 8 cousins". It's a quote from a biologist, Haldane. Its a notion of kin selection. It basically means we will favour our genes, but not our selves."
The male student was next, with a smirk on his face he said, "So are you suggesting we are selfish beasts and we are not created by God?"
The man heard this questions so many times, so he just recited his usual answer, "I am just teaching you what is there in the scientific community, it has nothing to do with my beliefs. And my beliefs are my own. I would appreciate if you hurry up, there are still people waiting."
The last was the girl. She smiled, a warm smile. She said, "I'm glad you are alive. You scared me back there. You haven't changed."
The man said, "No dear, I have changed. But as we discussed before I am low on Serotonin. No matter what happens I will have the same attitude."
"I'm sorry to hear that, old friend." Those were the girl's last words.
