Document Summary

If you"re comparing species then you need to take into account phylogeny. Important that it evolves more times in different branches. May not be able to isolate different factors. Some may not be able to do the experiment. Had control 1 which he didn"t touch at all. Had control 2 where he cut then reattached to see if handling the birds could be the problem. Need to make sure the controls you use are only testing for the presence of eye spots or not. Make sure the powder isn"t the change that increases predation. Crossing of peas to show how hereditary genes are passed. Rovers (cover a lot of ground) and sitters (much slower) Very few examples of genes directly affecting behaviour. On average phenotype patterns are a good predictor of genetic patterns. Proportion of phenotype variation can be explained by genetic variation. Antipredator behaviour is very similar in both parents and offspring.
