General
an English naturalist who developed a scientific explanation for how species change over generations
Who is Charles Darwin
an organism blends into its surrounding, making it harder for predators or prey to detect it.
camouflage
a polar bear's thick fur, a duck's webbed feet, and the shape of a finch's beak are all examples of which type of adaptation
Structural
occurs when humans choose organisms with desired traits to reproduce
Artificial selection or Selective Breeding
a natural process of evolution in which the organisms that are best adapted to their environment survive and are able to reproduce
Natural selection
the ship that Darwin began his voyage to the Galapagos Islands on
the HMS Beagle
the type of adaptation that is a physical feature of an organism
Structural Adaptation
bird migration, nocturnal activity, and animals taking turns watching for predators areall examples of which type of adaptation
Behavioral
the degree to which something varies; amount of change or difference
Variation
to fill with more inhabitants than available resources an sustain
Overpopulation
the type of animals that Darwin studied
Finches and tortoises
this type of adaptation is an action or pattern of behavior that helps an organism survive
Behavioral Adaptation
a camel conserving water and some polar fish producing antifreeze proteins is an example of which adaptation
Functional Adaptation
a group of living thins that can mate with one another but not with those of other groups
Species
a change in an organism, over time, that better enables it to survive and reproduce
Adaptation
what did Darwin observe about finches on he Galapagos Islands
finches had different beak shapes suited to different food sources
this type of adaptation is also called a physiological adaptation and is an internal body process that helps an organism to survive
Functional Adaptation
A harmless insect resembles a stinging wasp. Which adaptation does this demonstrate?
Mimicry
who is the Father of Evolution
Charles Darwin
the evolutionary principle that only the forms of plants or animals best suited to or most easily able to adapt to existing conditons will survive, while other less suited forms will become extinct
Survival of the fittest or natural selection
the title of the book Darwin published in 1859
On the Origin of Species
an organism resembles another organism or a feature of another organism
Mimicry
an Arctic Fox, which changes its thick fur coat from brown in the summer to bright white in the winter is an example of
Camouflage
a sudden, apparently abnormal change or alteration in a genetically determined structure, as opposed to gradual evolutionary change
Mutation
the theory that describes how all life forms developed from simpler life forms by change that took millions of years
Evolution
