The process by which species cease to exist is
What is extinction?
Yellow beetle and green beetles live in the rainforest canopy. You would expect:
The green population will increase and the yellow will decrease?
What is the vocabulary for "survival of the fittest"?
What is Natural Selection?
Darwin observed that the shape of these finches _________ were well matched with the seeds available in their own distinct environment.
Beaks
The process through which species change over time
Evolution
The process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals
Natural Selection
What is most likely to happen to moth populations in the picture shown?
Dark moths--hunted easily, dark moths--population decreases.
Does natural selection typically take a long time or a short time?
A Loooooooooooooooooooooooooooooooooooooong time?
This is how giraffes evolved long necks.
More long-necked giraffes survived to pass on their genes.
Preserved remains of once-living organisms
Fossil
What is a change in a gene that results in a new trait?
What is a mutation?
What would happen if the environment changes drastically and no organisms have fitting adaptations?
A species could go extinct
In an arctic environment, which would survive longer: red foxes or white foxes?
White foxes
Can an organism "CHOOSE" to evolve and change?
No, organisms CANNOT CHOOSE to change their genes or traits!
Who authored the book On the Origin of Species by Means of Natural Selection?
Charles Darwin?
A TRAIT that helps an organism to survive and reproduce in its environment
What is Adaptation?
After traveling to the Galapagos Islands, Darwin noticed a lot of variation among beak sizes in Finches. This variation was a result of:
Developing different adaptations in order to survive on particular islands
Darwin began to hypothesize that organisms developed traits over time because of the differences in their ___________.
Environments
A characteristic that an organism can pass on to its offspring through its genes.
Trait
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
