Evolution
Define Evolution.
What is the long gradual change that an organism progresses through to become a new specie. This process takes a long period of time. Gradual change in an organism over time?
Define Adaptation
Define Natural Selection.
What is a process by which traits that are passed from parents to offspring increasing a population of organism's chances of survival and ability to reproduce offspring?
The process by which sediments are laid down one on top of another is known as
What is deposition?
An individual plant; an individual animal; or a single-cell life form. Using your Geologic Time Scale single celled organisms first appeared on the Earth during the ____________.
What is an organism? What is Precambrian?
Darwin and Wallace came up with the idea of natural selection. They are also both known for the concepts of (name one) . . . . . . .
What is common ancestor and/or common decent.
Give an example of a characteristic.
A characteristic is facial features, nose shape, color of skin, eye color, color of hair, length of fingers, curly hair, straight hair, etc.
Natural Selection is a __________ by which evolution works on a population of organisms.
What is a process?
Relative dating can give . . . . . . . . .
The chronological sequence of events or order to life on Earth without providing the exact date of the event or order that life appeared on Earth. Uses the Law of Superposition!
Latin name that follows the Genus name of an organism. It is part of the taxonomic classification system.
What is species?
All members of the Genus or species are gone from the Earth. There are no members remaining to breed / mate and produce offspring is defined as . . . . . . . . . . .
What is extinction?
Characteristics help organisms ________ and ________ in their environments.
What is adapt and evolve?
If a bird beak is adapted to perform a specific function what process will act on the organism to change the beak over time so the organism is better suited to it's environment?
What is natural selection?
Fossils of animals that lived in the ocean are found in this type of rock.
What is sedimentary rock?
Define Biodiversity. . . . . . . . . . What does mass extinctions do to the Earth's biodiversity?
What is all of the living organisms that have adapted to live on the Earth. This allows for organisms to evolve into new organisms on the Earth. Not all organisms evolve before becoming extinct? Mass extinctions reduce biodiversity.
The belief that the universe and living organisms originate from specific acts of divine creation and not evolution . . . . . . . . . . . . . .
What is Creationism?
There are two major types of characteristics by which organisms can adapt?
Why is variation so important to evolution? Give an example of variation in a species of organism.
Without variation (different traits or characteristics) natural selection cannot act on the better suited traits because they are all the same traits. Different color shells (light and dark shades) of the same species of scallops.
Name the theory that best the movement of Earth's crust?
What is Plate Tectonics? Convection currents in the mantle cause the plates to move across the surface of the Earth.
What happens when DNA is damaged or changes. It can have positive or negative affects on a population of organisms. When positive the trait increases in the population.
What is a mutation?
Name four (4) or five (5) forms of evidence for evolution?
What are geologic distribution, plate tectonics, embryology, fossils, homologies, genetics?
Adaptations are closely related to characteristics. What is the main difference in the definition of characteristics and traits.
Characteristics are observable (phenotype) and some traits are hidden traits found in an organisms genetic makeup (genotype).
What is necessary for natural selection to change species into new species?
What is deep time?
Name three Eras from your Geologic Time Scale and place them in order from the youngest to the oldest. During which Era were the dinosaurs common?
What are the Cenozoic, Mesozoic and Paleozoic Eras? Dinosaurs were common during the Mesozoic Era!
With respect to the Wallace Line and Geologic Distribution.
Marcupial mammals (i.e., kangaroo) are found on the ____________ plate. Placental mammals (i.e., monkey) are found on the _____________ plate.
Marcupials are found on the Australian plate and placentals are found on the Asian plate.
