In the 1800s, Charles Lyell emphasized that
gradual geological events of past could explain the features
Earth is very young.
all populations evolvethrough natural selection.
the human population willoutgrow the available food supply.
5
Darwin's Theory of Natural Selection-certain individuals survive longer-have offspring
it is due to choices made by plant and animal breeders.
pocess inherited adaptations that are suited to environment
they possess adaptations developed through use
lack of competition within the species
6

The (2) main ideas with regards to the natural world that were challenged by Darwin
finches are abundant
don't go exploring or you fall off the edge of the world
world was 6,000 years old and unchanging
all species are fixed
20
Which of the ideas, proposed by Lamarck,was found to be INCORRECT
acquired characteristics can be inherited
all species were descended from other species
living things change over time
organisms are adapted to their environment
21

sedimentary rock
the sap of ancient trees
ice
rusty water

no idea
All species today evolved from a common ancestral species.
Inherited Acquired Characteristics

Charles Darwin observation of finches of different species on the islands had similar features
all eat the same type of food
acquired traits through use and disuse
orginated from a common ancestor
have grown larger since Darwin's visit
