Presentation Transcript

  1. Darwin’s Theory of Evolution • Change over time; the process by which modern organisms have descended from ancient organisms.

  2. Darwin’s Theory of Evolution • Preserved remains of ancient organisms. When Darwin compared them to living organisms, variations were observed.

  3. Darwin’s Theory of Evolution • Two Geologists who shaped Darwin’s thinking. (The last names of both geologists must be given).

  4. Darwin’s Theory of Evolution • The concept that each living organism has descended, with changes, from other species over time is referred to as.

  5. Darwin’s Theory of Evolution • Nature provides the variation, and humans select those variations that they find useful.

  6. Darwin’s Theory of Evolution • Structures that have different mature forms but develop form the same embryonic tissues.

  7. Darwin’s Theory of Evolution • According to this principle, all species – living and extinct – were derived from a common ancestor.

  8. Darwin’s Theory of Evolution • An organ that serves no useful function in an organism.

  9. Darwin’s Theory of Evolution • Any inherited characteristic the increases an organism’s chance of survival.

  10. Darwin’s Theory of Evolution • His hypothesis on evolution included the inheritance of acquired traits.

  11. Darwin’s Theory of Evolution • This means that members of each species compete regularly to obtain food, living space, and other necessities of life.

  12. Darwin’s Theory of Evolution • Islands that Darwin traveled to and extensively explored. He found much evidence for evolution on these specific islands. • For Example: Darwin saw variation in finch beaks and tortoise shells at these islands.

  13. Darwin’s Theory of Evolution • Each living species has descended with changes, from other species over time.

  14. Darwin’s Theory of Evolution • What is one piece of evidence for evolution?

  15. Darwin’s Theory of Evolution • The ability of an individual organism to survive and reproduce in its natural environment is called:

  16. Darwin’s Theory of Evolution • Which scientist formulated the theory of evolution through natural selection?

  17. Darwin’s Theory of Evolution • Who published their ideas first? Darwin or Lamarck?
