4 Steps of Natural Selection
100
What is the definition of Adaptation?
What is a trait that helps an organism survive and reproduce in its environment.
100
What is the definition of Punctuated Equilibria?
What is the theory that species evolve over during short periods of rapid change.
100
Define and give examples of physical adaptations.
What is a characteristic in an animal's body that helps it survive in its environment Ex. polar bears fur helps it survive in the cold waters An Elephants thick skin makes it harder for predators, lions, to harm. The hooves of the horse allow it to walk on rocky areas.
100
Countershading..
What is ocean animals with dark backs and white belles helps animals to not be seen from below by predators.
100
Overproduction...
What is an animal having too many offspring and all of them are not able to survive because of lack of food, living space, water, shelter, etc..
200
What is the definition of Species?
What is a group of similar organisms that can mate with each other and produce fertile offspring.
200
What is the definition of Fossil Record?
What is found in museums, labs, etc...
200
Define and give examples of behavioral adaptations.
What is things animals do to survive Ex. Possums pretend they are dead when they have spotted a predator Birds fly south in the winter so it is warmer for them Bears hibernate in the winter to avoid the harsh cold winter
200
Warning...
What is some animals have spines, poisons, and armor that shows they are too poisonous/ dangerous to be eaten
200
Variations...
What is the differences between individuals in a species. Ex. one turtle offspring being able to swim faster than another one, the faster= easier to get away from predators.
300
What is the definition of Theory of Evolution?
What is the species gradually changed over generations and became better adapted to new environment proposed by Charles Darwin.
300
What is the definition of Natural Selection?
What is the process by which individuals that are better adapted to their environment are more likely to survive and reproduce than others of the same species.
300
Who was Charles Darwin? What theory did he propose? What evidence did he use to support this theory?
What is a English naturalist who established that all species of life have descended over time from common ancestors. Ex. Differences in finch beaks between the islands. His theory was that the branching pattern of evolution resulted from a process called Natural Selection.
300
Camouflage...
What is coloration that helps animals blend in with their surrounding to not be seen by their predators.
300
Competition...
What is fighting for resources such as water, food, shelter from predators, etc..., but in an indirect way
400
What is the definition of Evolution?
What is the gradual change in a species over time.
400
What is the definition of a Branching Tree Diagram?
What is probable evolutionary relationships among organisms.
400
What three things might happen to a species when the environment changes?
What is animals can gradually become extinct, the species might adapt to the environment with new characteristic, and get a change in diet because of the new environment.
400
Disruptive...
What is spots/ stripes help fish blend in with the coral in their environment
400
Selection...
What is when some animals in a species are better adapted to an environment because of their variations, then others not being able to survive
500
What is the definition of Gradualism?
What is when evolution occurs slowly but steadily.
500
Advertising...
What is coloration that attracts other animals and the coloration advertises a special service
500
What three types of evidence do scientists use to determine if species are related?
What is DNA/ proteins, homologous structures, and early development.
500
False Eye Spots...
What is unusual color patterns that hide a part of an animals body. Ex. black dot on a fish may look like the fishes eye but really isn't
