All of the preserved remains/traces of organisms that we as humans have collected around the world across generations.
What is the fossil record?
The change in species heritable traits within a population, across generations.
What is Evolution?
The preserved remains or traces of an organism that lived in the past.
What are fossils?
Hip bones in whales, leg bones in snakes, and wings on a penguin are all examples of what?
What are vestigial structures?
Another key principle that states that species traits have different forms from one individual to another.
What is variation?
Observing anatomical structures of organisms and determining if they show evidence or a common ancestor, homologous, analogous, and vestigial structures are part of this.
What is Comparative Anatomy?
A change in genetic information.
What is a mutation?
The measure of an organism's ability to survive based on its traits and adaptations?
What is fitness?
These are passed down from parent to offspring based on a organism's genetic makeup: hair color, eye color, nose shape, are all examples.
What are inherited characteristics/traits.
The study of the early developmental stages of species, that shows common ancestry through common traits in these early stages.
What is embryology?
The struggle between organisms and other organisms or between organisms and their environment.
What is competition?
This is what Charles Darwin identified in his book The Origin of Species as the driver behind the process of Evolution.
What is Natural Selection?
This is a segment of genetic material found in a cell.
What is a gene.
What are acquired characteristics/traits?
The study of where species live on the planet and how that has affected their development. Tortoises on the Galapagos Islands are similar to those in South America but better adapted to island life.
What is Biogeography or Geographical Distribution?
These are anatomical structures with the same parts but widely different functions.
What are homologous structures?
