Miscellaneous
100
Change in a species over time
What is evolution
100
When nature provides the variations and humans select those they find useful
What is artificial selection
100
An inherited characteristic that helps an organism survive and reproduce in its environment
What is an adaptation?
100
They share a common structure
What are homologous structures?
100
Example of a vestigial structure
What is appendix in humans, hip bones in dolphin, etc.
200
Any remains or trace of an ancient organism
What is a fossil?
200
They suggested that the Earth is much older than a few thousand years.
Who are Hutton and Lyell
200
How well an organism can survive and reproduce in its environment
What is fitness?
200
A structure that is inherited but no longer has a function
What is vestigial
200
The process that produced different beak sizes in finches on the Galapagos Islands
What is natural selection
300
He observed variations in the species on different islands of the Galapagos?
Who is Darwin?
300
He suggested that organisms could change during their lives and pass those acquired characteristics to offspring
Who is Lamarck?
300
Process by which individuals with helpful variations survive and leave more offspring
What is natural selection?
300
An example of analogous structures
What are a bird wing and an insect wing
300
The large ground finch obtains food by cracking seeds. Its short strong beak is an example of this
What is an adaptation?
400
An example of evolution happening today.
What is antibiotic-resistant bacteria OR new diseases
400
His ideas got Darwin thinking about overproduction of offspring and competition for resources
Who is Malthus?
400
Natural selection happens when there is variable ______ among offspring.
What is fitness?
400
This shows that the early stages of development are similar for different species
What is embryology?
400
These structures are NOT evidence of a common ancestor
What is analogous?
500
One of the patterns of biodiversity Darwin observed.
What is species vary globally, species vary locally, or species vary over time
500
Darwin realized that this provides the raw material for evolution.
What is variation?
500
This happens if an environment changes faster than a species can adapt.
What is extinction?
500
Similarities in these molecules suggest a common ancestor
What are DNA and proteins
500
The conditions under which natural selection occurs.
What is overproduction of offspring, variation in traits, and species with different fitness.
