Something that can be inherited through genetic characteristics... means that everyone is different!
What is variation?
100
Provides a record over time, shows that ancient species have similarities to modern ones
What are Fossil Records?
100
In natural selection, this is the agent that "selects" for or against traits of an organism.
What is the environment?
100
Changes in the gene pool of a small population due to change; bottle neck and founder effect
What is Genetic Drfit?
100
Any trace or remains of a once-living organsim that has been preserved by natural processes.
What is a fossil?
200
Adapted organisms often have more ____________ that will survive.
What is offspring?
200
Some species have homologous structures
What is Comparative Anatomy?
200
The four concepts that natural selection depends on
What is Variation, Inheritance, Overproduction, and Reproductive Advantage?
200
Structure in one organism that is a reduced form of a functional structure in another organism
What is Vestigial Structure?
200
One species gives rise to many species in a short period of time
What is Adaptive Radiation?
300
When organisms try to get their fair share of a limited amount of resources.
What is competition?
300
Species that have a common ancestor have similar stages of development
What is Comparative Embryology?
300
When a species adapts to look like its environment allowing it to hide from predators
What is Camouflage?
300
Scientists who studies fossils
What is a Paleontologist?
300
Random changes in alleles due to changes in the genetic code
What is a Mutation?
400
The process whereby organisms that have advantages survive and pass their genes onto their offspring.
What is natural selection?
400
Species with a recent common ancestor share certain amino acid sequences
What is Comparative Biochemistry?
400
Evolution will not occur in a population unless allele frequencies are acted on by forces that cause change
What is the Hardy-Weinberg Principle?
400
When a physical barrier splits one population into two or more populations; if enough time passes, they will no longer be able to breed, therefore becoming separate species.
What is a Allopatric Speciation?
400
The appendix or tail bone in humans
What is a Vestigial Structure?
500
On the black sand beach of Hawaii there are 2 beetle colonies, one silver and the other black. This color beetle is better adapted to live in this environment.
What is black?
500
The four main pieces of evidence we have for evolution?
What are Fossil Records, Comparative Anatomy, Comparative Embryology, and Comparative Biochemistry?
500
This can be inferred about the evolutionary history of 2 species if they share homologous structures
What is they share a common ancestor at some point?
500
When some event wipes out most of a population. The remaining allele frequencies may be very different based on which individuals survive
