100
The adaptation of a species to better suit its environment over a long period of time.
What is Evolution?
100
Ensures survival rate of offspring
What is over-production?
100
Occurs over mates, food, water, land etc.
What is competition?
100
The islands that Charles Darwin visited while taking a journey on the HMS Beagle.
What are the Galapagos Islands?
100
Genetic mutations, genetic isolation and migration, and selective breeding
What is how new species are formed (speciation)?
100
The preserved remains or traces of an organism from the past.
What are fossils?
100
A historical sequence of life indicated by fossils found in layers of the Earth's crust.
What is the Fossil Record?
100
This structure(s) prove whales came from a walking organism.
What are the pelvis and femur?
200
A group of organisms that can breed naturally in nature and have fertile offspring.
What is species?
200
Scientific term for having "healthy offspring"
What is successful reproduction?
200
Inherited variation, over production, competition, successful reproduction
What are the 4 steps to Natural Selection?
200
The name of an organism that caused Darwin to consider the theory of evolution.
What are tortoises, lizards, or finches?
200
A change in the genetic material which can cause variation in a population.
What is a mutation?
200
The process by which populations accumulate inherited changes over time.
What is evolution?
200
The division of Earth's 4.6-billion-year history into distinct intervals of time
What is the geological time scale?
200
These are examples of...
What are homologous structures?
300
Genetic differences between individuals within a species
What are Variations?
300
The process that evolution occurs due to slow changes that result in big changes in the end.
What is gradualism?
300
The ability to survive and reproduce in an environment.
What is fitness?
300
How species evolve
What is adapting to their environment?
300
Breeding of organisms that have a certain desired trait
What is selective breeding?
300
All these structures help prove evidence on evolution
What is homologous, analogous, and vestigial structures?
300
Prove there is a common ancestor through having similar structure and different functions
What are homologous structures?
300
Goosebumps, wisdom teeth, tail bone, appendix...
What are examples of human vestigial structures?
400
An inherited trait that enhances an organisms ability to survive. (Favorable variation) leads to....
What is Adaptation?
400
States that evolution happens in quick occurences
What is punctuated equilibria?
400
Relationship between variations and adaptations.
What is favorable variations lead to adaptations?
400
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
400
New species is formed because there is some barrier separating the same species causing them to evolve.
What is genetic isolation and migration?
400
Structures that no longer have a function.
What are vestigial structures?
400
The studying of bone structure and organs
What is anatomical evidence?
400
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?
500
An explanation of an idea that is broad in scope and supported by a lot of evidence.
What is a Scientific Theory?
500
Occurs quickly due to natural disasters, causing punctuated equilibria.
What is catastrophism?
500
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?
500
Organisms develop traits over successive generations, especially as a result of natural selection.
What is the theory of evolution by natural selection?
500
The process by which two populations of the same species become so different that they can no longer interbreed.
What is speciation?
500
Used to prove there is no common ancestor as the body structure is different but the organisms may use that body part for the same function
What are analogous structures?
500
The study of similarities in the early development of embryos.
What is embryology?
500
When anatomy is similar it proves the organism comes from...
A common ancestor
