Phylogenetic Tree of Life - ANSWERS3 Domains, 6 Kingdoms
Domains: Bacteria Archaea Eukarya
Eukaryotic Kingdoms: Animals Plants Protista Fungi
Conclusions from 3 Domains - ANSWERS1) All species to ever live form a branching
tree of evolutionary relationships ( TREE OF LIFE)
2) All living things descended from a common ancestral population
3) Over time, descendants of common ancestral population diversified to produce
biodiversity on TREE OF LIFE
Metazoans - ANSWERSmulticellular organisms with tissues and organs
Great Themes of Evolutionary Biology - ANSWERS1) Why are there millions of

Natural Selection - ANSWERSA process in which individuals that have certain inherited
traits tend to survive and reproduce at higher rates than other individuals because of

2) History of life on Earth
3) Relationships among living things past + present
4) Why organisms have similarities and differences
5) How species evolve by descent with modification
6) Use of Scientific Method
Fundamental Components of Evolutionary Thought - ANSWERS1) Phylogenetic
Thinking: Shared evolutionary history (macroevolutional)
2) Population Thinking: Evolutionary change in population (microevolutional)
3) Natural Selection: Evolution is descent with modification (adaptations)
Importance of Evolutionary Biology - ANSWERS1) Agriculture ex) Selective Breeding
ex) Pesticide Resistance in Crop Pests
2) Disease Control ex) Antibiotic Resistance in Bacteria
