Theory
Who discovered the theory of natural selection?
Charles Darwin
What is evolution
Change of population over time
What’s natural selection?
The process through which populations of living organisms adapt and change.
What is artificial selection
Process in which a particular trait is chosen to force onto an organism and it’s traits and evolution
what is some evidence of comparative anatomy?
Homologous structures
What is a theory?
Speculation or guess that is based off observations and original knowledge
How do organisms evolve?
Organisms survive and reproduce offspring and pass on their advantageous traits to the next generation.
What’s the difference between artificial and natural selection?
Natural selection happens naturally and artificial selection happens when humans intervene.
True or false: artificial selection is most responsible for evolution
False, natural selection
What is evidence of common ancestry?
Comparative embryology
How does Darwin explain how shell shape or tortoises help them survive?
Curved shells allow them to reach vegetation, and dome shaped shells because vegetation was more abundant
What’s random mutations?
Creates changes in dna and changes phenotypes
True or false: natural selection is the survival of the biggest and strongest
False, survival of the fittest
Why is artificial selection used for foods?
It allows humans to mold organisms to their needs. Humans choose which are more beneficial and which they don’t want to survive any longer.
What is biogeography?
Geographic distribution of species
Why were the Galapagos islands important to the formation of Darwin’s theory of evolution?
Showed that species in isolation tended to evolve in ways that suited their environments.
Why do organisms with greater fitness generally leave more offspring than organisms that are less fit?
The stronger organisms are able to adapt to the environment the greater their chance of surviving leading to increase in their pop after reproduction.
What does struggle for existence mean
When more individuals are produced than survived
Is the selection of moths that blend into their environment an example of artificial selection and why?
Yes, it was intervened by humans.
What is molecular biology
Compared DNA sequences between organisms
What are the five parts included in a theory?
Data, records, insight, experiments, analysis
What are the 5 evidences of evolution?
Fossil records, biogeography, comparative anatomy, comparative embryology, molecular biology
What sort of organism does natural selection produce?
One that can survive and reproduce
Obesity, diseases, health disorders, reduced brain size.
How does ancestry relate to common descent
Common descent an relate to the common ancestry of living organisms including genetic methods.
