ANT211H5 Lecture Notes - Ontogeny, Pronucleus, Egg Cell
Document Summary
The ability to reproduce viable offspring and then having those offspring to reach sexual maturity and go on to reproduce themselves. Being able to perpetrate your gene to further generations: asexual vs. sexual reproduction, idea of the costs of reproduction, exam* 4 ways to answer the question why when it comes to behaviour in biology, proximate-structural or physiological. Direct biological explanation for that behaviour: ultimate- reproductive or adaptive explanation for the question why. Importance of ontogeny: life history strategy is a developmental chronology, sociobiologists cannot ignore analyses of the learning process, evolution must be understood as a modification of developmental processes over generations, must defuse the nature vs nurture controversy. Fertilization of the ovum: remember that gametes are different b/c female gametes are full of cytoplasm and contain the full energy/nutrients for further development of the baby. Where as males produce thousands of sperm and have very little cytoplasm, so they are more focused on fertilization.
