| What are characteristics of divergent evolution by adaptive radiation? | Homologous structures. Even though they might look superficially different they have the same underlying structure because they came from the same ancestor. the structure is used for different things though. example- pentadactyl limb |
| What are some characteristics of convergent evolution? | This is where two different ancestors give rise to analogous structures in descendants. Streamline appendages is an example, they have the same function even though they may not look the same |
| Outline adaptive radiation | 1. ancestral species survives natural disaster/placed in a new environment
2. members of species face different selection pressures
3. members of the species adapt to better suit their environment, and eventually this leads to speciation
4. this is an example of divergent evolution by adaptive radiation. for example, the pentadactyl limb |
| what is the immediate effect of producing more offspring than environment can support? | fight for survival where some make it and others die |
| How is the fossil record evidence for evolution? | Complexity of organisms increase as the fossil record goes on. first bacteria, then fungi, then vertebrates |
