Darwin's scientific theory of evolution explains and predicts this.
What is species changing over time
A scientist in Alaska has two dogs, one of his dogs has naturally thick fur, while the other has naturally thin fur. He loses them on an expedition and has to leave them behind. The two dogs mate to produce offspring with features like this
What is mostly dogs with thick fur
Red bugs were once dominant in an environment, over time green bugs were becoming the dominant color. Give one environmental advantage green bugs may have had.
They were not eaten by birds and were able to reproduce
Three layers in the ocean have similar fossils. Layer B fossil (top layer) did THIS from the fossils in layer A (bottom layer).
Formed as a result of change; evolved
How do images of different birds beaks support Darwin's theory of evolution?
They show the same species evolving over time
What is camouflage?
An adaptation that organisms have to survive in their environment
According to the theory of evolution through natural selection, which organisms are most likely to survive.
Organisms who have adapted to living conditions
Gray wolves typically do better in colder environments, due to their coats. Brown wolves typically do well in warmer environments. Which species would increase in response to global warming?
What is Brown wolves
Evidence that life on Earth has changed over time that is buried within the Earth are called what?
Fossils
Two similar fossils are found in the Earth's crust, which fossil could you say evolved from the other?
The fossil closest to the surface evolved from the one deeper in the Earth's crust
What is evolution?
Change over time
In what way could cacti better adapt to be less likely eaten by predators?
Develop more thorns to deter animals
One type of turtles have very long necks, while the other have short necks. A drought came to their environment, which caused low vegetation to vanish. What would happen to those turtles with short necks?
They would become extinct, because they can't reach high vegetation.
I have an empty bookcase with six shelves to model the layers of fossils. Where should I put the oldest and newest fossil?
Oldest - bottom shelf
Newest - top shelf
What is adaptation?
An inherited behavior or physical characteristic that helps an organism survive and reproduce in its environment
T/F Natural selection happens extremely rapidly to develop advantageous traits in populations that are facing changes in environmental conditions.
TRUE
Silver or transparent fish are better adapted to survive in fresh water, because why?
They blend in with the water
T/F - A strain of bacteria becoming resistant to antibiotics is an example of natural selection.
TRUE
Most animals who live in the arctic, have white fur coats. Why would this be the case in order for them to survive?
White fur helps them blend in with their surroundings
