5 Multiple Choice Questions
- Gradualism and Punctuated evolution
- Anagenesis is the evolutionary change within a single lineage
- Mutualistic coevolution is when both species benefit through mutual exploitation. this is never altruism
- Plants will often reuse chemical secondary compounds found in other lineages. This allows beetles to jump hosts.
- It is argued that when a localized population diverges, the probability of finding a fossil of such a small population is low. It isn't until the divergence has occurred and population numbers rise that fossils are found
5 True/False Questions
what are mirror image phylogenies? → Anagenesis is the evolutionary change within a single lineage
What is an example of specific pairwise coevolution? → Aphids and their bacteria, Buchnera. Buchnera live in bacteriocytes in Aphids and synthesize amino acids. They are transmitted vertically from aphid to offspring.
What is an example of high phenotypic diversity and high species diversity? → Salamanders are diverse in species but not in phenotype
What is coevolution? → Macroevolution describes longterm patterns of evolutionary diversification among higher taxa (genera, families). Macroevolution asks what patterns we can see when looking at the world with a broader time scale
What is the pattern of virulence over time? → Virulence will often, but not always, decrease over time
