| Frage | Antworten |
| Socioecology | studying how the social system evolves in response to ecological conditions how social & physical environment affects behaviour |
| Behavioural Ecology | studying the relationship of distribution, morphology, behaviour and social organisation of habitats |
| Analogous Features | similar features that evolved independantly but have similar functions and therefore similar structures similarity based on function e.g. bird's wing + bat's wing |
| Homologous Features | similarity based on ancestry similar features that evolved from common ancestry and therefore share similar structure e.g. bird's wing + human hand bones |
| Vestigial Features | genetically determined structures that have lost their ancestral function but are still retained through evolution e.g. human appendix |
| Atavistic Features | the return or partial return of features that were common in ancestors e.g. modern horses with extra toes |
| Cladogenesis | evolutionary splitting where a parent species splits into two distinct species |
| Anagenesis | evolution of species involving change in a lineage over time without speciation |
| Convergent Evolution | separate lineages that were quite different but became similar due to similar lifestyles |
| Homoplasy | when ancestrally unrelated structures look alike e.g. leaf insect + leaf |
| Phylogenetic constraint | 'basic body plan' of a species which cannot be altered by evolution can be modified but never completely changed |
