- 1Adaptive radiation=Lineage rapidly diversified, newly formed lineages evolving different adaptions
- 2Hydracotherium=Earliest horse-like form
- 3Merychippus=True horse line
- 4What adaptions does grass have against herbivores?•High silica content(munchy when eating)
•Apical meristem is close to ground - 5George Gaylord’s main contribution?Making da people understand dere was side lineages yagetme fam
- 6Horses good example of evolution in a single lineage because?Traceable over time
- 7Examples at the level of genus are:•Darwin’s finches
•Honeycreepers + Drosophila
•Cichlids fishes - 8Anagenesis=Change within one lineage
- 9Cladogenesis=Splitting of a lineage
- 10Founding populations subject to different selection pressures cause:1)No competing species
2)No predators
3)Larger islands spatially more heterogenous - 11Factors leading to rapid evolution:•Competition for limited resources
•Sexual selection - 12Convergent evolution=Between members of 2 lineages-response to similar habitat selection pressures
