Kin selection, broadly, refers to evolutionary strategies where a focal individual improves the reproductive success of closely related individuals. The idea is that helping your relatives indirectly increases your fitness because closely related individuals also carry your genes. Some kin selection related behaviors are referred to as "altruistic" because they are costly to the one performing them (e.g. giving some of your food to your cousin) -- however, kin selection theory would say that "this cost is more than offset by the indirect benefit of helping a relative who shares your genes". It's more complicated than that, but that's the idea.
Nice video. If you want more fun examples/measurements of competitive exclusion (with some evolutionary game theory sprinkled in) then here's one in cancer:
Really cool paper! I'm always looking for examples/papers that apply ecological theory to topics connected to medicine (many of the undergraduates I interact with are interested in medical school). What a great example!
What exactly do you mean by random? Mutations occur randomly, but natural selection does not. Rather, natural selection acts on existing genetic variation, and this is an important part of the story.
From your comment I understood that animals that preceded polar bears, already had a predisposition for a right mutation to occur. It was taken from a pool related to the weather conditions. Well, that adds some sense and in fact that is in the line of my thinking
I liked the video. The paradox of pesticides reminded me of cat colonies: people say cats eat pests but they destroy pests' predators also, so having cat colonies can lead to more pests.
Definitely agree that you need to figure out who your target audience is. If it’s the general public, you’ll definitely need to scale back on the mathematics.
Thanks so very much for taking the time to write this -- these are just the kinds of criticisms I've been looking for! (I've filmed a couple videos, so it will be a little bit until I can truly put your criticisms to good use!)
House centipedes are nice to keep around (if they don't freak you out -- a lot of people can't tolerate having them around)! They are pretty shy, can't hurt you, and they do a good job taking care of pests.
Thanks for a detailed answer. I have removed the cost of dove-dove interaction.
Cool video! Thanks for sharing!!
I see, but I think it is also reffered to as mixed-ESS when two strategies co-exist. While the other is pure ESS, when only ony strategy is stable.
I should have clarified this earlier.
Good vid man, the visuals were really effective alongside your explanations. Subbed
Thanks so much! More to come soon (hopefully!)
Always happy to get some feedback!
Really great video! I love that you filmed outside, that was somewhat unexpected for a small channel but for me it really makes it more engaging!
Thanks so much for watching and your kind words!
I'm always happy to get feedback!
Great explanation! Really hooked me from the beginning.
Thanks! I'm really glad you enjoyed it!

Comments and criticisms are very welcome!
So, I lost steam after answering questions 1, 2, and 5, but maybe they will be informative for the rest.
Hey there! I'm a PhD student (not at an Ivy League, but a school I would consider comparable... dm me if you want details).
Hey there -- I'm a theoretical ecologist and I'm happy to help!

"Already had a predisposition for a right mutation to occur"
I assume you mean "two people getting the same mutation at the same site".
