Adaptation A characteristic that improves an individual's ability to survive and reproduce
in a particular environment.
descent with modification an ancestral species could diversify into many descendant
species by the accumulation of adaptations to various environments (By Charles Darwin)
Evolution explains how Earth's many species are related through descent from common
ancestors and how these species have diverged over time.
Darwin's Theory of Evolution Earth's many species are descendants of ancestral species
that were different from those living today.
Aristotle (Greek) Generally viewed species as perfect & permanent.
Genesis Species were individually designed by a divine creator, man added the
interpretive view that the Earth was <6,000 yrs. old.
Fossils Imprints or remains of organisms
-Mid 1700's people noticed they weren't just rocks
-Lived in the past revealed a succession of forms in layers of sedimentary rock that differed
from current life forms.
Jean-Baptiste Lamarck (Early 1800's) Suggested the best explanation for the relationship
of fossils to current organisms is that life evolves.
, Jean-Baptiste Lamarck Lamarck is best remembered for inheritance of acquired
characteristics wherein, for example, he suggested that giraffes have long necks today because
their ancestors had lengthened their necks by stretching ever higher into the trees to reach
leaves (i.e., use or disuse of body parts may change those traits and change what is passed on
to offspring).
Lamarck was wrong, but his advocacy of evolution and his proposition that species change as a
result of interactions with their environment, laid the "ground work" for Darwin.
HMS Beagle In 1831, Darwin traveled to the Galapagos islands aboard the HMS Beagle
on a 5-yr. cruise.
Goal of Darwins trip: to chart the South American coastline, but the voyage included
stops at Australia and Africa.
What did Darwin collect? plants, animals, and fossils.
Things Darwin did on His trip: He noted lots of differences between mainland and island
forms of flora and fauna. He noted South American fossils looked more like present-day South
American animals and plants than they resembled fossils on other continents.
Darwin was influenced by Charles Lyell's new book "Principles of Geology"
What did Darwin realize? natural forces gradually changed Earth's surface and that these
forces are still operating in modern times
[Lyell said this and Darwin absorbed it and applied to living things], but Darwin witnessed a
volcanic eruption in Chile and other forces of nature, which left no doubt in his mind that Lyell
was CORRECT. Darwin seriously doubted the Earth to be only a few thousand years of age. The
growth of mountains due to earthquakes could explain the marine snail fossils that he had
collected on mountaintops in the Andes.
