QuestionAnswer
Species A group of similar organisms that can mate with each other amd produce offspring
Variation any difference between individuals of the same species
Evolution The order by which modern organisms have descended from ancient organisms.
Carolus Linnaeus The man who developed the first scientific system for classifying living things
Jean-Baptiste-Lamarck The man who made the Theory of Transformation.
Charles Lyell The man who made the Theory of Gradual evolution over long periods of time.
Fossil The preserved remains or traces of an organisms who lived in the past.
Mary Annings A woman who discovered many fossils we know today.
Scientific Theory A well tested explanation for a wide range if observations and experimental results.
Mechanism The natural process by which something takes place.
Artificial Selection Breading certain animals to get a desired trait.
Natural Selection A process by which individuals that are better adapted to their environment survive and reproduce more than others.
Origin of Species A Theory by charles Darwin.
Three factors the affect the process of natural selection Overpopulation, Variation, and Competition.
Competition The struggle among living things to get necessary amounts of food, water, and shelter.
Mutation Any change to the genetic material.
Epigenetics The study of small changes to the DNA that tuns genes on or off.
Gene Expression Determines how a cell acts.
Fitness How well an organisms can survive and reproduce in its environment
Two ways mutations are created Damages DNA, and Errors while copying DNA due to radiation.
Example of Harmful and beneficial mutations Harmful: Fruit Fly Mutation Beneficial: Moth Mutation.
Gene Flow How alleles enter a population
Genetic Drift The shrinking of genetic variation over time.
Sexual Selection Natural selection that acts on an organisms ability to get the best possible mate.
Coevolution The process by which two species evolve in response to changes in each other over time.

Body Fossil The shape and structure of an organism.
Trace Fossil Fossils of things an organism did.
Embryos A young organism that developed from a fertilized egg.
Homologous Structures Similar structures that related species have inherited from a common ancestor.
How are species formed When one population is isolated from the rest enough to evolve their own traits.
How can rapid evolution of a species happen? When a major change in the environment occurs,
Extinct If it no longer exists and will never live on earth again

LUCA The Last Universal Common Ancestor
Three Domains of Life Bacteria, Eukarya, and Archaea
Protein A large molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.
What are 2 ways that genetic material can move from one species to another When on cell engulfs another, or when bacteria share DNA with other cells.
Gene Transfer The transfer of genes from one species to another.
Symbiosis The organisms of different species that have a close relationship to each other.
Endosymbiosis The reason for Prokaryotic cells to evolve into Eukaryotic cells.
Darwins Journey He set on a 5 year trip around the world onboard a British navy ship
Adaptations An inherited behavior or Physical Characteristic that helps an organism survive and reproduce in its environment.
