The Theory of Evolution

Theory of Evolution and Natural Selection

How or WHY have organisms changed over time?

Who is Darwin?

• Father of Evolution

• Came up with Evolution through Natural Selection

Multiple Choice

Who is the Father Of Evolution?

• Mendel

• Darwin

• Newton

Darwin's Voyage

• Sailed on the HMS Beagle

• Ships naturalist (Studied nature) and captains companion

• Traveled and studied in South America and the GALAPAGOS Islands

Multiple Choice

Darwin did NOT travel to

• Asia

• South America

• Galapagos Islands

Darwin's Fossils

• In South America Darwin found lots of fossils

• Noted how these fossils looked similar to living creatures

• Fossils of Woolly rhinos, Giant Ground Sloths, GIant armadillos, Mastodons, etc

Darwin and the Galapagos

• Also studied animals on the Galapagos Islands

• Noted Finches looked similar to the finches on mainland South America

• But they had different beaks for different food sources

Multiple Choice

What adaptation do Darwin's finches have?

• More Feathers

• Different Beaks

• Different Songs

Theory of Evolution

• Descent with modification

• Change over time

Open Ended

Look at the image, what do you think will happen?

Multiple Choice

What is the gradual change in species over time?

• Evolution

• Adaptation

• Natural Selection

Multiple Choice

To adjust to a changing environment

• Mutation

• Adapt

Multiple Choice

Another word for adapt is

• Change

• Create

What is Natural Selection?

• "Survival of the fittest"

• Whatever organisms are best suited to an environment will pass on their traits to offspring

• Nature is selecting the strongest

• Whether that is coloration/ camouflage, biggest, tallest, smallest, smartest, etc
