james hutton - ANSWER✔✔-realized that rocks formed through imperceptibly slow changes; observable

processes produce small changes that accumulate over time; earth must be old


william smith - ANSWER✔✔-noticed that different rock layers contain distinct fossils


george buffon - ANSWER✔✔-proposed that earth had formed according to the laws of physics over more

than 70,000 years; each species had a supply of organic particles


jean-baptiste lamarck - ANSWER✔✔-believed traits acquired in a lifetime were passed to offspring and

that simple organisms always evolved to more complex organisms


charles darwin - ANSWER✔✔-unofficial naturalist on HMS Beagle, published Origin of the Species, first

to propose a correct mechanism for how life changed over time; descent with modification, natural

selection


alfred russel wallace - ANSWER✔✔-had similar ideas to charles darwin about evolution and natural

selection;


charles lyell - ANSWER✔✔-earth's landscapes had been created by many small changes, not gigantic

catastrophes


what is the Great Chain of Being? why did scientists stop using it to categorize the natural world? -

ANSWER✔✔-origin in ancient Greek philosophy; species are arranged on a scale from lower to higher
