18 Questions
Why is the fossil record considered biased and incomplete?
Soft tissue decomposes and is rarely preserved
What can molecular analysis reveal that differs from expectations based on morphological and fossil data?
Relationships
What is a way phylogenetic trees are used in conservation, as mentioned in the text?
To understand environmental pressures and combat poaching
How are phylogenies crucial in the understanding of viruses, diseases, and cancer?
They can be used to study disease spread
What are homologies in evolutionary biology?
Structural similarities due to common ancestry
What is radiometric dating used to determine?
The absolute timing of speciation
What is the half-life of Carbon-14?

What is the traditional classification system of living things separated into?
Five different kingdoms
What is systematics?
The study of both taxonomy and phylogenetics
What are morphological traits used for in phylogenetics?
To classify organisms based on shared traits due to common ancestry
What do ancestral vs derived characters, synapomorphy, and outgroup comparison help identify in phylogenetic analysis?
Traits and evolutionary relationships
What is the purpose of an outgroup comparison in identifying traits in phylogenetic analysis?
To distinguish ancestral from derived characters
What are the three domains in the three-domain system of classification?
Bacteria, Archaea, Eukarya
When does convergent evolution occur?
When similar adaptations develop independently in unrelated organisms living in similar environments
Which isotopes are used to date items that are 10 million to 4.5 billion years old?
Potassium-40 and Uranium-238
What is the inability of phylogenetics to account for rapid speciation events and evolutionary reversals an example of?
Limitation in capturing all aspects of evolutionary history
List the hierarchical classification system used in taxonomy (list each 7 of the classifications separated by commas).
• Kingdom, Phylum, Class, Order, Family, Genus, and Species
The rules for binomial nomenclature are relatively lenient in the scientific community.
