Tool that allows things to move slowly in one direcion. A geneic load when one mutaion adds to another and adds to another, etc. Sexual reproducion, because it"s recombinaion, reduces the mutaional load. Asexual reproducion mutaion load builds up (all ofspring coninuously get mutaions) Lead to load geing so heavy that the populaion can go exinct (muller"s ratchet) Diferent male tacic, choose ater year one to become parental or sneaker. Ofspring of sneakers were actually bigger than parental male ofspring. Gape-limited predaion (the bigger you are the less mouths you it into) Some species we know its inherited, but in this case it may be condiional. Compeiion of sperm from two or more males in ferilizing female eggs. Unlike overt male-male compeiion that happens pre-copulaion, this compeiion is more subtle. Sperm compeiion took a long ime for people to realize. Male yellow dung lies come to females.
