Ecology Unit 4 Vocab quiz

Taxonomy

• structures in different species that are similar in function but not in structures. NOT COMMON ANCESTRY
• The scientific study of how living things are classified
• newly developing organisms
• a feature that evolved only within the group under consideration

Evolution

• The scientific study of how living things are classified
• a feature that evolved only within the group under consideration
• structures in different species that are similar in function but not in structures. NOT COMMON ANCESTRY
• The gradual change in a species over time

Natural Selection

• Ability of an organism to survive and reproduce in its environment
• A process in which individuals that have certain inherited traits tend to survive and reproduce at higher rates than other individuals because of those traits.
• a family tree that shows the evolutionary relationships thought to exist among different groups of organisms
• The gradual change in a species over time

Descent with Modification

• structures in different species that are similar in function but not in structures. NOT COMMON ANCESTRY
• The gradual change in a species over time
• An ancestral species from which later species evolved
• principle that each living species has descended, with changes, from other species over time

Common Ancestor

• a key for the identification of organisms based on a series of choices between alternative characters
• An ancestral species from which later species evolved
• a feature that evolved only within the group under consideration
• the evolutionary history of an organism

binomial nomenclature

• Ability of an organism to survive and reproduce in its environment
• The system of assigning a scientific name that consists of two parts: Genus species
• The gradual change in a species over time
• newly developing organisms

Phylogenetic Tree

• English natural scientist who formulated a theory of evolution by natural selection (1809-1882)
• a key for the identification of organisms based on a series of choices between alternative characters
• a family tree that shows the evolutionary relationships thought to exist among different groups of organisms
• The gradual change in a species over time
