Unit 7 Life over time vocabulary

Evolution

• A change in the structure or amount of the genetic material of an organism
• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The process in which inherited characteristics within a population change over generations such that a new species sometimes arise
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals

Mutation

• The process in which inherited characteristics within a population change iver generations such that a new species sometimes arise
• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The occurrence of hereditary or nonhereditary differences between different individuals of a population
• A change in the structure or amount of the genetic material of an organism

Artificial Selection

• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The human practice of breeding plants or animals that have certain desired traits
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
• The occurrence of hereditary or nonhereditary differences between different individuals of a population

Natural Selection

• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
• The occurrence of hereditary or nonhereditary differences between different individuals of a population
• The human practice of breeding plants or animals that have certain desired traits

Variation

• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
• The occurrence of hereditary or nonhereditary differences between different individuals of a population
• The human practice of breeding plants or animals that have certain desired traits

Extinction

• The death of every member of a species
• The history of life in the geological past as indicated by the traces or remains of living things
• The occurrence of hereditary or nonhereditary differences between different individuals of a population
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals

Adaption

• A characteristic that improves an individuals ability to survive and reproduce in a particular enviroment
• The occurrence of hereditary or nonhereditary differences between different individuals of a population
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
• The process in which inherited characteristics within a population change over generations such that a new species sometimes arise

Fossil

• The death of every member of a species
• The trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock
• The history of life in the geological past as indicated by the traces or remains of living things
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals

Fossil Record

• The death of every member of a species
• The trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock
• The history of life in the geological past as indicated by the traces or remains of living things
• The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
