The adaptation of a species to better suit its environment over a long period of time.
What is Evolution?
Ensures survival rate of offspring
What is over-production?
Occurs over mates, food, water, land etc.
What is competition?
The islands that Charles Darwin visited while taking a journey on the HMS Beagle.
What are the Galapagos Islands?
Genetic mutations, genetic isolation and migration, and selective breeding
What is how new species are formed (speciation)?
The preserved remains or traces of an organism from the past.
What are fossils?
A historical sequence of life indicated by fossils found in layers of the Earth's crust.
What is the Fossil Record?
What are the pelvis and femur?
A group of organisms that can breed naturally in nature and have fertile offspring.
What is species?
Scientific term for having "healthy offspring"
What is successful reproduction?
Inherited variation, over production, competition, successful reproduction
What are the 4 steps to Natural Selection?
The name of an organism that caused Darwin to consider the theory of evolution.
What are tortoises, lizards, or finches?
A change in the genetic material which can cause variation in a population.
What is a mutation?
The process by which populations accumulate inherited changes over time.
What is evolution?
The division of Earth's 4.6-billion-year history into distinct intervals of time
What is the geological time scale?
These are examples of...

What are homologous structures?
Genetic differences between individuals within a species
What are Variations?
The process that evolution occurs due to slow changes that result in big changes in the end.
What is gradualism?
The ability to survive and reproduce in an environment.
What is fitness?
How species evolve
What is adapting to their environment?
Breeding of organisms that have a certain desired trait
What is selective breeding?
All these structures help prove evidence on evolution
What is homologous, analogous, and vestigial structures?
Prove there is a common ancestor through having similar structure and different functions
What are homologous structures?
Goosebumps, wisdom teeth, tail bone, appendix...
What are examples of human vestigial structures?
An inherited trait that enhances an organisms ability to survive. (Favorable variation) leads to....
What is Adaptation?
States that evolution happens in quick occurences
What is punctuated equilibria?
Relationship between variations and adaptations.
What is favorable variations lead to adaptations?
Why did organisms of the same species evolve?
They had been separated for a long time from one another and had to adapt to their environment
New species is formed because there is some barrier separating the same species causing them to evolve.
What is genetic isolation and migration?
Structures that no longer have a function.
What are vestigial structures?
What is anatomical evidence?
Given the data below what is the Fish's most recent common ancestor?
Frog - 75%
Toad - 62%
Shark - 82%
Dolphin - 45%
What is a shark?
An explanation of an idea that is broad in scope and supported by a lot of evidence.
What is a Scientific Theory?
Occurs quickly due to natural disasters, causing punctuated equilibria.
What is catastrophism?
The process by which organisms with favorable traits survive and reproduce at a higher rate than organisms without the favorable trait.
What is Natural Selection?
Organisms develop traits over successive generations, especially as a result of natural selection.
What is the theory of evolution by natural selection?
The process by which two populations of the same species become so different that they can no longer interbreed.
What is speciation?
What are analogous structures?
The study of similarities in the early development of embryos.
What is embryology?
When anatomy is similar it proves the organism comes from...
A common ancestor
