2 Standard HS-LS 4-5: Evaluate the evidence supporting claims that changes in environmental conditions may result in: (1) increases in the number of individuals of some species, (2) the emergence of new species over time, and (3) the extinction of other species FLT I will be able to explain how the isolation of populations can lead to speciation by completing 11.5 Power Notes.

3 Power Notes Noise level 0 Raise your hand to question/ comment Write down all bolded information 11.5: Speciation Through Isolation Key Concept: New species can arise when populations are isolated Recall What is a species? It is a group of similar organisms that can reproduce and have fertile offspring Speciation The'rise'of'two'or'more'species'from'one' exis3ng'species' 3&

Behavioral barriers/isolation: differences in mating behaviors prevents reproduction between populations Reproductive isolation can be caused by 2.

Patterns in Natural Selection 1. Convergent Evolution! 2. Divergent Evolution! 3. Coevolution Convergent Evolution Unrelated species evolve similar traits Occurs due to similar environments/ pressure 8&

9 4/25/15& Divergent Evolution Coevolution Related'species'evolve'different'characteris3cs'due' to'different'environments.''' Example:'adap3ve'radia3on.''One&species,&such&as& finches,&evolves&into&many&species&occupying& different&environments.'& Coevolution: Two or more species evolve in response to changes in each other! Coevolution Beneficial relationships: Both species benefit from each other s adaptations Beneficial relationships! Evolutionary arms races Coevolution Evolutionary arms races: Species change & compete against each other through adaptations over many generations 9&

10 4/25/15& Patterns in Speciation 1. Punctuated Equilibrium! 2. Adaptive Radiation Adaptive Radiation One species evolves into MANY species adapted to different environments! This is a type of divergent evolution Punctuated Equilibrium Quick bursts of speciation are followed by long periods of little evolutionary change Extinction Elimination of a species from Earth! 1. Background extinction! 2. Mass Extinction 10&

11 4/25/15& Background Extinction Random and slow. Affects only a few species in a small area.! Can be caused by changes in environment Pair-Share-Respond 1.
