Vocab and Basics
This is an inherited behavior or physical change that helps an organism survive and reproduce in its enviorment?
What is an adaptation?
This is collection of data shows patterns of how life on Earth has changed over millions of years?
What is the fossil record?
This is the best way for scientist to prove a modern-day animal evolved from a specific fossil.
What is comparative anatomy?
In an enviroment with only tall trees, these herbivorse are most likely to survive and reproduce.
Who are individuals with longer necks?
This is what GMO stands for.
What is genetically modified organism?
This term refers to any difference between individuals of the same species?
What is variation?
According to the Law of Superposition, this fossil layer is the oldest in an undisturbed rock sequence?
What is the bottom layer? (layer one)
These are body parts that are structural similar in different species and indicate a common ancestor?
What are homologous structures?
This explains why a population with high genetic variation is more likely to survive a new disease?
What is some individuals may have a natural resistance?
This is the primary difference between natural and artificial selection.
What is that humans choose the traits in artifical selection while enviromental pressures drive natural selection.
Natural selection is affected by these three factors.
What are overproduction, variation, and competition?
If scientist find fossils in a dry desert, they can infer this about the regions past enviorment?
What is the region was once submerged under water? (an ocean)
This is what similar bone structures in a whale flipper and human arm suggest.
What is they share a common ancestor?
In a sandy environment, these colored beetles are more likely to be eaten by predators? (dark or light)
What are the dark beetles?
This is the major benefit of developing genetically modified, cold-resistant plants.
What is they can be grown in a wider variety of enviorments?
These two biological factors describe an organisms 'fitness'?
What are survival and reproduction?
What are is the first step of fossilization?
The organism dies in/near a body of water and the soft parts are eaten by predators/decay?
These structures are used for the same purpose but have different internal structures and origins?
What are analogous structures?
This factor gives a population a much higher probability of survival when their habitat conditions chnage rapidly.
What is more genetic variation?
This is what aims to reduce the symptoms of genetic diseases.
What is gene therapy?
This is what happens to the frequency of a helpful trait in a population over time?
What is increases?
Comparing the anatomies of living species with the fossil record helps biologists reconstruct this?
What is evolutionary history?
This is the likely reason why tree frogs in forest are gray while those in wetlands are green?
What is natural selection (or adaptive coloration/camoflage)?
This occurs when individuals move into or out of a population, transferring their genetic material to a new group.
What is gene flow?
This is the goal of a scientist who only takes seeds from corn plants that stay fresh the longest?
What is artificial selection?
