Evolution Vocabulary

Natural Selection is a process by which:

• species evolve over time through the survival of individuals that are better adapted to their environment

• individuals choose their mates based on specific traits

• organisms are artificially selected by humans for desired traits

• random genetic mutations occur in a population

What is a Fossil?

• A type of rock

• A preserved remain or trace of a living organism from the past

• A type of mineral

• A type of plant

What is Homology?

• A similarity in sequence of a protein or nucleic acid between organisms of the same or different species.

• A process of cell division that results in two daughter cells.

• A type of chemical reaction involving the rearrangement of atoms.

• A method of classifying organisms based on their physical characteristics.

A Descendant is:

• a person, plant, or animal that is descended from a particular ancestor

• a type of ancestor

• a historical figure

• a type of plant

Adaptation is:

• a process of change by which an organism or species becomes better suited to its environment

• a sudden change in an organism's genetic structure

• a temporary adjustment to a new environment

• a random mutation with no specific purpose

What is the Fossil Record?

• A collection of ancient manuscripts

• A historical archive of life on Earth preserved in fossils

• A record of human history

• A database of geological formations
