Study Notes
Evidence for Evolution
- Picture Vocabulary: Illustrates evolutionary changes in a horse lineage (Equus, Pliohippus, Merychippus, Mesohippus).
- Descent with Modification: Evolution is the process of species changing over time, originating from preexisting species.
Biogeography
- The geographical distribution of species: Focuses on the current and historical locations of various bird species (Rhea, Ostrich, Kiwi, Emu, Cassowary), highlighting biogeographical patterns.
- Study of Species Distribution: Biogeography examines where species live and why they are found in certain places.
Homologous Structure
- Similar Structures across Species: Shows the bone structures of different animals (whale, frog, horse, lion, human, bird), demonstrating shared ancestry and common origins.
- Common Ancestor: The similar structures in different animals suggest a common ancestor that they all derived from.
Analogous Structure
- Similar Function, Different Ancestry: Exhibits the structures of a butterfly and a bird, illustrating that similar features can evolve independently in unrelated species to solve similar problems.
Comparative Embryology
- Embryonic Development Similarities: Displays the embryonic stages of several species (shark, lizard, chicken, pig, human), demonstrating similarities in early development indicating shared ancestry.
Fossils
- Preserved Remains: Illustrates a fossil, signifying the remnants or traces of ancient plants and animals.
- Historical Evidence: Fossils provide evidence of past life forms, thereby lending insight into evolutionary history.
Fossil Record
- Layered Sedimentary Rock: Depicts layers of sedimentary rock with embedded fossils.
- Chronological Order: The order of fossils in the layers indicates the relative ages of the organisms.
Natural Selection
- Differential Survival and Reproduction: Highlights the concept that organisms with traits better suited to their environment are more likely to survive and reproduce, leading to changes in population over time.
- Inherited Traits: Natural selection acts upon inherited traits that affect an organism's survival and reproduction.
Gradualism
- Slow and Gradual Evolution: Illustrates a theory that proposes species evolve slowly and steadily over long periods.
Punctuated Equilibrium
- Rapid Evolutionary Change: A theory that suggests rapid periods of evolutionary change follow long periods of little change.
- Intermittent Evolution: This evolutionary model contrasts a gradual, constant evolution model.
Stasis
- Stable Species Over Time: Shows an example of a species remaining relatively unchanged over long periods.
Rock Strata
- Layers of Sedimentary Rock: Displays layered sedimentary rock, showing the different layers have a roughly similar composition throughout their respective layers.
