Evolution
True or False - Darwin's ideas were not influenced by the work of other scientists like geologists & naturalists
False
True or False - Lamarck said that individual organisms could change during their lifetimes by selectively using or not using various parts of their bodies
True
Heritable characteristic that increases an organism's ability to survive & reproduce in an environment
Adaptation
The study of past and present distribution of organisms
Biogeography
How well an organism can survive & reproduce in its environment
Fitness
Name one of the 3 patterns of diversity Darwin saw on his voyage.
Species vary locally, species vary globally, species vary over time
True or False - Evolution means that a species becomes better over time
False
Which kind of adaptation: tiger's claw
Body part or structure
Structures that are similar in different species of common ancestry
Homologous structures
High or low fitness - a tiger with long claws better able to climb & catch prey
High fitness
Preserved remains of, or traces of, ancient organisms
Fossil
Selective breeding of plants & animals to promote the occurrence of desirable traits in offspring
Artificial selection
Which kind of adaptation: avoidance of predators
Behavior
Body parts that share a common function, but not structure
Analogous structures
The discovery of what let scientists figure out the age of the Earth?
Change over time; the process by which modern organisms have descended from ancient organisms
Evolution
Some cows producing lots of milk and some producing a little amount of milk is an example of?
Inherited variation
Which kind of adaptation: camouflage
Color
Hox genes are an example of?
Molecular homology
In natural selection, the _________________________ influences fitness, not a farmer or animal breeder
Environment
Darwin proposed how modern organisms evolved though descent from common _____________________
Ancestors
Process by which organisms that are most suited to their environment survive & reproduce most successfully
Natural selection
Which kind of adaptation: the way a plant carries out photosynthesis
Physiological changes
Structure that is inherited from ancestors but has lost much or all of its original funciton.
Vestigial structure
Name one of the 3 things that need to exist in order for natural selection to occur
The struggle for existence, variation & adaptation, or differential reproductive success
