What is the vocabulary for "survival of the fittest"?
What is Natural Selection?
100
Which variation is the best in humans?
A height of 69 inches
100
The process through which species change over time
Evolution
200
The process where species with good traits get to survive and reproduce, and ones with bad traits die
Natural Selection
200
In a light environment, what will happen to the population of each of the moths?
Dark moths--hunted easily, dark moths--population decreases.
200
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
200
Based on this graph, what is the independent and dependent variable?
Independent: Height
Dependent: Number of people
200
Preserved remains of once-living organisms
Fossil
300
What is a change in DNA that results in a new random trait?
What is a mutation?
300
What determines which variation is the best for a species?
Example: What helps decide which color moth was the best?
The environment
300
Does adaptation to choose the right trait for an environment typically take a long time or a short time?
A Long time
300
Based on the graph, which bird beak type is the better adaptation?
short, fat beaks
300
Who authored the book On the Origin of Species by Means of Natural Selection?
What is Charles Darwin?
400
A TRAIT that helps an organism to survive and reproduce in its environment
What is Adaptation?
400
What would happen if mutations and new adaptations did not happen in a new species?
The species would die and go extinct
400
In an arctic environment, which would survive longer: red foxes or white foxes? Why?
White foxes. Because the white fur will blend in to their environment
400
Over time, Hawaii started to make more plants that produce nuts and seeds. Why did the short and fat beaks increase more than the long, curved beaks?
Short fat beaks are the better adaptation because they can crack open the nuts and seeds more easily.
400
The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?
Dark moth
500
The different versions of one trait in a population
Exapmle: Dark skin and light skin
Variation
500
What happened to the long and curved beaks. You must use natural selection and adaptation in your answer.
Natural selection occurred because the fat beak birds could crack the seeds and the long beaks could not.
500
A characteristic that an organism can pass on to its offspring through its genes.
Trait
