- Precision and accuracy
- what are the six kingdoms
- Genetic bottleneck
- example of directional selection
- how is evolution both fact and theory
- a The fact is that life changes over time The theory regards the mechanisms that enable change over time
- b a reduction in the allele frequency because of genetic drift on a small population because of a dramatic reduction of the size of a larger population.
- c precision is the absence of vaugeness and ambiguity. Accuracy is how close observations or predictions are to the empirical truth.
- d large cliff swallows survived because they had more fat stores in a cold snap so the large allele became dominant for survival. might not be fixed though
- e bacteria, archaea, protists, plantae, fungi and animalia

- ts that existed in a common ancestor.
- "in same place" geographically yet barriers to gene flow are established. isolation may occur because of reproductive cycle times like flowers releasing pollen early can lead to speciation.
- 1. isolation of populations
2. divergence of traits
3. reproductive isolation
- trait that is a reduced or incompletely developed structure that has no function or has reduced function but is clearly similar to functioning organs on closely related species.
5 True/False questions
Phylogenic tree → depicts the pattern evident in the history of decent groups of organisms it's more of a hypothesis.
Phylogeny → testable statement of relationships which can be confirmed or falsified a hypothesis driven inquiry is self correcting
two types of characters → not due to inheritance similarity is the result of convergence (parallel evolution) where different organisms adapt for similar functions in similar environments in unrelated Lineage's like birds and bats both have wings.
Applied science → the observation identification description experimental investigation and theoretical explanation of natural phenomena
does natural selection change individuals → no just populations
