Document Summary
*i only type up the extra things he says during the lectures :p look at the powerpoint for the rest. 3rd point will be favoured by natural selection. Right now we are benefitting from the positive value. Tp53 (cid:373)akes p53 (cid:449)hi(cid:272)h is a (cid:862)(cid:373)agi(cid:272) protei(cid:374)(cid:863) that prote(cid:272)ts us fro(cid:373) tu(cid:373)ours, a(cid:374)d if (cid:449)e are la(cid:272)ki(cid:374)g that gene, then we are suffering from cancer. Causes premature aging but can use this to possibly cure cancer. Ultimate explanation as opposed to proximate explanations. Natural selection encourages genomes to get delayed aging effects. Real world includes a large amount of interactions between species. We classify species interactions by who benefits and who suffers. Species 1 tends to follow the logistic equation. Competition equation, k1 n1, shows that the breaking is like species 1, but we also subtract a12n2, to show that species 2 may not be taking as much resources as species 1.
