Document Summary
We can look at evolution of behavior because we can study. Evidence for a genetic component of a behavior. Most high levels of pkg lead to increase in mobility, movement, Pkg plays an important role in foraging. In worm, the dwelling behavior is much more like sitter in high levels of pkg genes. Birds used to migrate to spain but now migrate to england (novel; migration route since 1950) This could be learned: take pairs from wintering site in england. Hand raise them in isolation from age 6 or 7 days. Test them in emlen funnels during autumn migration. Emlen funnel: it will try to scramble in the direction it wants to go in cage, leave imprints on the funnel: take 6 or 7 day old youngfrom nests in south west. Adults from britain: west back to england. F1 offspring of british: west to england. Young from sw germany: sw to spain.
