Document Summary

Lecture 2 a refresher in evolutionary thinking. If this is parental care directed to descendant, then you will expect that care will be directed to(cid:449)ards so(cid:373)eo(cid:374)e"s o(cid:449)(cid:374) ki(cid:374) (cid:448)s so(cid:373)eo(cid:374)e else"s.

Scientific method: observation hypothesis prediction test. Okay a dog wags its tail, but why what is the significance, why did it evolve. Why is a worker honeybee sterile (cid:272)o(cid:373)e up (cid:449)ith e(cid:454)pla(cid:374)atio(cid:374)s for thi(cid:374)gs that do(cid:374)"t see(cid:373) o(cid:271)(cid:448)ious (cid:449)h(cid:455) the(cid:455)"re happe(cid:374)i(cid:374)g. Prediction: what would you expect to happen if hypothesis is true. Prediction: larger people will eat more (not hypothesis) If this behavior is paternal care, then i expect immediate descendent care. T-test is test of a prediction which will have come from a hypothesis.
