  1. Number your notebooks as far as you can in 5 mins • Remember: Odd #s always on right side • Write your name/period/McCobb/ C-1 on the front of your book • On Pg. 1 Write your: • Edmodo code and pw • OARs code and pw

  2. 10.1 Early Ideas About Evolution 2.1 Atoms, Ions, and Molecules Set up Cornell Notes on pg. 3 • Topic: 10.1 Early Ideas About Evolution • Essential Question: • Why are the ideas that the Earth undergoes change and is billions of years old important for evolutionary theory? • Why are the ideas that the Earth undergoes change and is billions of years old important for evolutionary theory?

  3. Points to Ponder • Have you ever heard the expression of “survival of the fittest”? • What does it suggest to you?

  4. KEY CONCEPT There were theories of biological and geologic change before Darwin.

  5. EVOLUTION • Evolution-is a process of biological change by which descendants come to differ from their ancestors

  6. A species is a group of organisms so similar to one another that they can reproduce (have babies) and have fertile offspring (babies who can have babies).

  7. Early Ideas about Evolution (pg. 3) Erasmus Darwin Jean-Baptiste Lamarck Carolus Linnaeus Georges Louis Leclerc de Buffon • . • . • . • . • . • . • . • . • . • . • . • .

  8. Carolus Linnaeus • Swedish botanist • Opened a classification system for all types of organisms • He grouped them by their similarities • System reflects evolutionary relationships

  9. Please classify these animals into groups based on their similarities.

  10. Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Carnivora • Family: Canidae • Genus: Canis • Species: Canis Lupus • Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Primates • Family: Hominidae • Genus: Homo • Species: Homo Sapiens • Kingdom: Animalia • Phylum: Chordata • Class: Mammalia • Order: Carnivora • Family: Felidae • Genus: Felus • Species: Felus Catus

  11. Georges Louis Leclerc de Buffon • He proposed that species shared ancestors instead of arising separately • Rejected the idea that Earth was 6000 years old. He suggested that it was much older

  12. Erasmus Darwin • Grandfather of Charles Darwin • Proposed that all living things descended from a common ancestor and that more-complex forms of life arose from less complex forms of life

  13. Jean-Baptiste Lamarck • Proposed that all organisms evolved toward perfection and complexity • He did not think that species became extinct- He thought they evolved into different forms • Environmental change leads to use or disuse of a structure

  14. Theories of Geologic Change (pg. 2) (p.299 in book) Georges Cuvier Charles Lyell James Hutton • Uniformitarianism • . • . • . • Gradualism • . • . • . • Catastrophism • . • . • . PICTURE PICTURE PICTURE

  15. There were three theories of geologic change. • Catastrophism- natural disasters have happened often during Earth’s long history • These events shaped landforms and caused species to go extinct Georges Cuvier

  16. 2) Gradualism-slow changes over a long period of time The Colorado River carving the Grand Canyon James Hutton

  17. 3) Uniformitarianism-Changes are uniform through time and occur at a constant rate Charles Lyell

  18. Uniformitarianism is the prevailing theory of geologic change.
