Evolution
Changes in a species over time
What is a mutation?
A random change in DNA. Can be beneficial, harmful, or neutral
Differences within a species. Important for evolution.
When humans decide which organisms survive and reproduce.
Direct, intentional changes to the DNA of an organism
What is variation?
A random change in DNA. Can be beneficial, harmful, or neutral
Differences within a species. Important for evolution.
When humans decide which organisms survive and reproduce.
Direct, intentional changes to the DNA of an organism
What is artificial selection?
A random change in DNA. Can be beneficial, harmful, or neutral
Differences within a species. Important for evolution.
When humans decide which organisms survive and reproduce.
Direct, intentional changes to the DNA of an organism
What is genetic modification?
A random change in DNA. Can be beneficial, harmful, or neutral
Differences within a species. Important for evolution.

Teosinte is the ancestor plant of modern-day corn. Unlike corn, Teosinte had only a few, tough kernels to eat. Over time, humans chose specific teosinte plants to breed together to produce plants that were better to eat. Which trait would humans most likely have selected for to make teosinte more edible?
Denser roots to dig deeper into the ground
Larger leaves to catch more sun
Softer kernels to be gentler on teeth
Smaller seeds to spread out better
The dodo bird is an extinct species of bird that could not fly. Instead, it had powerful legs to run quickly. The dodo bird was know for making its nest on the ground. Because of this, it was often the target for human hunters in the 1600's. The dodo birds were hunted faster than they could reproduce. Ultimately, the selection was too strong and the dodo bird went extinct. What kind of selection took place here?
Natural Selection
Stabilizing Selection
Disruptive Selection
Artificial Selection
MRSA is a type of bacteria that is very difficult to kill with antibiotics. It is sometimes found in hospitals and other settings where antibiotic use is high. This bacteria often infects patients who already have a weakened immune system. What might be the cause of this bacteria's antibiotic resistance?
MRSA was able to reproduce more quickly because of all the body heat in the hospital.
MRSA became more resistant over time to antibiotics because the bacteria who survived passed on their resistance to new bacteria.
MRSA is a naturally resistant bacteria. It just happened to make its way into hospitals.
MRSA gained its resistance by surviving the use of cleaning products like bleach and soap.
A bird living in a forest has a rare mutation that causes its feathers to change from brown to green. This mutation also makes the bird sterile and unable to reproduce. What is the most likely outcome for this mutation?
The green feathers mutation will become more common over time because it helps the bird camouflage in trees.
The green feathers mutation will not spread beyond the original bird because it cannot reproduce.
The green feathers mutation will become more common because it makes it easier for the bird to fly.
The green feathers mutation will become less common because it causes the bird to die early.
Artificial selection is also called (a)
The Galapagos finches are similar birds, but have different beaks and different songs. They also have different patterns on their feathers. They use these differences to recognize their own species. How might this be useful to the finches?
It helps the finches communicate better with other species of finches.
It ensures that finches can find mates of their own species.
It confuses predators and allows the finches to escape them better.
It stops the finches from identifying each other easily.
How do homologous structures help provide evidence for the theory of evolution?
They show that all organisms have the same body parts, no matter where they live.
They show that different organisms have the same patterns of bones, suggesting a common ancestor
They show that organisms separately developed body parts that look different but do the same job.
They show that some organisms have more in common with each other than others.
How is artificial selection different from genetic modfication?
Artificial selection happens naturally, while genetic modification is done by humans.
Artificial selection is direct modification of the gene, while genetic modification happens randomly.
Artificial selection requires mating specific members of a species over and over, while genetic modification changes the DNA directly.
Artificial selection can only happen in a lab, while genetic modification can happen in the wild.
Identify the type of adaptation in each example.
The ancestor of modern corn plants was called "teosinte." It was much smaller than corn plants and had only a few tough kernels. It took thousands of years of human activity to change teosinte into a more edible plant. Which of the statements is accurate about modern corn?
Teosinte evolved into corn through natural selection.
A behavioral adaptation changed teosinte into corn.
Teosinte evolved into corn due to artificial selection.
A single lucky mutation changed teosinte into corn.
