Evidence of Evolution The theory of evolution is supported by many scientists from many fields and many cultural backgrounds. Evidence can be found in 1. The Fossil Record 2. Biogeography

3. Anatomy 4. Embryology 5. Biochemistry FOSSIL EVIDENCE

Fossil Record traces the history of life Shows transitional fossils .Archaeopteryx Eustheoteron Animal Armageddon:

Eustheopteron Seymouria Amphibian or reptile? Therapsid

mammal or reptile? FOSSIL RECORD HISTORY OF THE HORSE Ancestor of Modern Whales

Ambulocetus had hind limb BIOGEOGRAPHICAL EVIDENCE Distribution of plants and animals

No rabbits in S. America Explains the abundance of finch species Marsupials found in Australia Figure 17.14a

Figure 17.14b Figure 17.14c Figure 17.14d

Figure 17.14e Figure 17.14f ANATOMICAL EVIDENCE 1. Organisms

have anatomical similarities a) Homologous structures similar structures

inherited from a common ancestor (ex. Arm bones) Analogous structures inherited from unique ancestors, resemble each other because they serve the same

function (ex fins on sharks, fins on dolphins) See how analogies evolve Vestigial structures remains of a structure that was once functional (human tailbone)

The Flightless Cormorant (Phalacrocorax harrisi), also known as the Galapagos Cormorant, Adult Ozark Blind Cave Salamander (Eurycea spelaea).

Notice the smaller, degenerating eyes, the eye lids that are beginning to grow over them, and the reduced pigment. Embryological development all

vertebrates have the same basic pattern of development Which is the

human embryo? PIG FETUS Answer: All of them except the

one above, which is a pig. BIOCHEMICAL EVIDENCE DNA, Amino Acids, Cytochrome C are similar in related organisms

UNIFYING THEORY OF BIOLOGY Explain the diversity of living things on this planet

Explains the fossil record Explains biochemistry and anatomy **Don't forget that THEORIES are used by science to EXPLAIN phenomenon Chapter 17 - Overview

1. What scientific observations and research influenced Darwin? 2. List the steps involved in natural selection. How does a population change over time? What environmental factors push these changes? 3. Summarize the various kinds of evidence for evolution

(i.e., that all living organisms descended from a common ancestor) 4. In terms of evolution, what does "fitness" mean? 5. In science, an important part of a theory is that it is falsifiable.

What observations could refute the hypothesis that an adaptation evolved by natural selection? What observations could refute the theory of evolution? 6. A scientific theory stands or falls according to how well it is supported by the facts, not according to who believes it. Do you think higher education students should be

encouraged to *believe* evolution? 7. Should creationism or intelligent design be taught as an alternative to evolution? (See Project Steve) Darwin Awards? http://www.darwinawards.com/

Named in honor of Charles Darwin, the father of evolution, the Darwin Awards commemorate those who improve our gene pool by removing

themselves from it.
