16.2 Ideas That Shaped Darwin's Thinking Flashcards
What did Hutton discover?
He recognized the connections between geological processes. He discovered that these processes operated very slowly. Hutton concluded that because they operate slowly, the Earth must be very, very old.
What did Lyell discover?
He argued that the laws of nature are constant over time. Like Hutton, Lyell concluded that the Earth is very old.
How did Hutton and Lyell’s discoveries help Darwin’s theory?
Darwin wondered if the earth can change over time, could life change as well?
What was Lamarck’s wrong ideas?
Individuals can pass on acquired traits on to their offspring, and organisms could change during their lifetimes by using or not using parts of their bodies.
What was Lamarck’s right idea?
There is a link between an organism’s environment and its body structures.
What was Malthus’ idea?
He said if more offspring are born that die, their would not be enough food for everyone.
How did Malthus’ idea help Darwin?
He wondered which individuals survive, and why they survive
What is artificial selection?
When humans select animals with good traits to breed. That trait would be passed onto their offspring.
Give an example of artificial selection.
Farmers breeding chickens that lay the most eggs to create more offspring that also lay the most eggs.
