What can molecular analysis reveal that differs from expectations based on morphological and fossil data?
Molecular analysis can reveal relationships that differ from expectations based on morphological and fossil data.
What is a way phylogenetic trees are used in conservation, as mentioned in the text?
Phylogenetic trees are used to understand environmental pressures and combat poaching, as mentioned in the text.
How are phylogenies crucial in the understanding of viruses, diseases, and cancer?
Phylogenies are crucial as they can be used to study disease spread and provide insights into the behavior of infected individuals.
What led to many wrong classifications in Linnaeus' attempt to classify plants?
Homoplasies led to many wrong classifications in Linnaeus' attempt to classify plants.
What is the traditional classification system of living things separated into?
Five different kingdoms
What are the three domains in the three-domain system of classification?
Bacteria, Archaea, Eukarya
Why is the three-domain system gaining popularity?
Due to the increasing evidence of two very different branches of prokaryotic life
What is systematics?
The study of classification of organisms
What is radiometric dating used to determine?
The age of rocks or fossils based on their color
What is the half-life of Carbon-14?
5,700 years
Which isotopes are used to date items that are 10 million to 4.5 billion years old?
Uranium-235 and Uranium-238
What is used to determine evolutionary relationships based on homologies?
Morphological data
What are homologies in evolutionary biology?
Structural similarities due to common ancestry
What are analogies in evolutionary biology?
Similarities in appearance not due to common ancestry
When does convergent evolution occur?
When similar adaptations develop independently in unrelated organisms living in similar environments
What are morphological traits used for in phylogenetics?
To classify organisms based on shared traits due to common ancestry
