Process by which a species that is best adapted to their environment are able to survive and reproduce.
What is natural selection.
Fill in the blank: survival of the _____
Fittest
What causes evolution?
Natural selection and/ or mutations over generations
True or false: Evolution can create a new species in one generation.
False
Common ancestry suggests this.
That species are related by a common ancestor.
A permanent change of an organism's DNA causes a ________________.
What is mutation?
Any inherited characteristic that increases an organisms chance of survival.
What is an adaptation?
The more similar this 3 letter strand is between two species, the more closely related the two species are.
What is DNA?
Naturalist.
When a population changes over time to better suit their environment it is called this.
What is evolution?
This type of evidence supports the theory of evolution because it shows how different species have similarities during early development.
What is embryology?
What is the interaction of individuals that vie for a common resource that is in limited supply called?
What is competition?
Chimpanzees
When humans breed selected plants and animals to attain desired traits, it is called this.
What is artificial selection?
Is evolution and survival of the fittest the same thing?
No
True or false: Survival of the fittest is what determines which species is the strongest.
True
In an arctic habitat; are white foxes or grey foxes more likely to survive and why?
White foxes are more likely to survive becase their white coats help them blend into the snow
What is it called when more offspring is produced than can survive?
Overproduction
Speciation can occur when organisms are ___________.
What is isolated?
What is the evidence for evolution? Name two.
Body structures, fossil record, embryology, and DNA comparison
This is when evolution happens in little steps over a long period of time.
What is gradualism?
How are artificial selection and natural selection similar?
There are both processes that cause evolution.
What is the difference between natural selection and artificial selection?
Natural selection is when nature selects which new traits to arise, and artificial selection is when humans select which traits arise.
This type of selection is decided by the environment-not humans.
What is natural selection?
In an environment with food that grows on trees; are animals with long legs more likely to survive than animals with short legs and why?
Yes, animals with long legs, necks or any phenotype that makes them taller will be more likely to survive because they have easier access to food.
Your appendix is an example of which type of structure?
What is vestigial?
This process drives evolution to happen.
Natural selection.
This is when evolution happens with big changes over a short period of time.
What is punctuated equilibrium?
This type of evidence supports the theory of evolution by showing how past and present organisms have changed.
What are fossils?
Different sizes, colors, and shapes within a species are known as ___________________.
What are variations?
