Bird Beak
What type of birds did Darwin study in the Galapagos Islands?
Finches
There is a forest with all white trees, what color moth will be able to blend in?
The white moths
The idea that organisms that are best suited for their environment will survive is called what?
Natural Selection
What did Darwin notice about the birds that he studied?
He noticed that the birds were the same species, but they had different beaks depending on where they lived.
Explain how the color of the moth increases or decreases its chances of survival.
If the color of the moth is the same as the forest, it will be able to hide from predators easily. However, if it is not the same it will be easily seen and will be eaten by predators.
When an organism’s traits change over time to help them best suit the environment they live in, it is called....
Adaptation
In the following graph, which beak is most adapted to eat seeds?
Beak 2
Why are the black moths adapted to the polluted forest?
Their wing color matches the trees, so they are able to hide from predators.
What type of adaptation does a black moth have in a dark forest?
Camouflage
A bird in New Jersey has a beak adapted for eating caterpillars, what will happen if there is a sudden decrease in caterpillars?
The population might decrease, the bird might adapt to eat another food, or they might travel to a new place that has more caterpillars.
Based on the ladybug photo and the population, what color do you think the trees are where they live? Explain why.
There is a higher percentage of white ladybugs, so that is telling me the trees are white. They are able to blend into the trees better.
When an organism is able to live long enough to reproduce, what do they pass down to their offspring?
Their characteristics
If I saw a nectar drinking bird and an insect eating bird in my backyard, would they have the same beak? Explain why or why not.
They would not have the same beak because they eat different things. Their beaks would not be able to pick up the same foods.
There is a forest that has white trees, over time the pollution covered the trees in soot. Explain what will happen to the white & black moths that live there.
The white moths will not be able to camouflage with the trees anymore and they will be seen by predators. The black moths will be able to blend in, they will live long enough to reproduce.
What is it called when one organism starts to act or look like another organism? (We saw this with the butterflies!)
