Evolution 1
The process in which a species has changed over time is known as this.
What is evolution?
He is known as the Father of Evolution
Who is Charles Darwin?
Modern whales evolved from mammals that lived on land. Fossil evidence reveals that one characteristic that has changed over time is the position of whales’ nostrils. The images below show the skulls of a modern whale and its ancestor, Pakicetus.
Scientists think that the position of the nostrils gives modern whales an evolutionary advantage. Which of the following most likely describes how this adaptation is advantageous?
What is A? The nostril position allows whales to obtain air more easily at the surface of the water
Fossils found in layers of sediment give us clues to Earth's past. If marine fossils are found in a field what can be determined?
What is "The field was once underwater?
The oldest fossil are found in what part of rock?
What is the bottom layer?
Similar structures that evolved from a common ancestor such as bones humans, cats, bats, and whales have in common.
What are Homologous Structures?
Chameleons can change color to match the color of their surroundings. If a chameleon was born with a mutation that prevented it from being able to change color, why would it be unlikely to pass on this trait?
What is the chameleon would be unlikely to survive long enough to reproduce and pass on the trait.
Any inherited trait that increases an organism's chance of survival is known as this.
What is an adaptation?
Fossils are found in what type of rock?
Hint: You only have 3 to choose from
What is sedimentary rock?
A record of Earth changing over a long period of time
What is fossil record?
Preserved remains of ancient organisms
What are fossils?
Doctors once prescribed antibiotics automatically “just in case” an infection might happen. Now doctors are careful to avoid overuse of antibiotics. The change is based on what doctors understood about bacteria an natural selection. Which of the following statements best explains why doctors limit their use of antibiotics?
Refer to your Evolution 2, 300 card for answer choices
What is A. Doctors now know some bacteria have mutations that are resistant to antibiotics
Advantageous traits are more likely to be passed down from parent to offspring because.....
What is they are more likely to survive and reproduce?
An innate behavior some birds display in response to shortening day length, drop in temperature, or the beginning of winter?
What is migration?
A polar bear in a snow drift is an example of concealing coloration or ____________.
What is camouflage?
What characteristic did Darwin observe about the finches on the Galapagos Islands?
What are their beaks?
The concept of humans selecting desired traits in species.
What is Selective Breeding? OR Artificial Selection
An inherited structures that has lost all or most of its original function.
What are Vestigial Structures?
The differences among a species, like different bird beaks, are called.....
What is industrial variations?
The white feathers of a snowy owl allow it to blend in with its environment during the winter months (snow). This is an example of ________________
What is Adaptation?
Which term refers to the process by which individuals that are better suited to the environment survive and reproduce therefore passing down their genes to their offspring?
What is Natural Selection (Survival of the Fittest)?
The concept that members of each species fights regularly for food, space, and other necessities is known as this.
What is survival? or Competition
When an organism completely dies out.
What is Extinction?
Adaptations require 2 key components in order to become a permanent fixture in the DNA structure to give rise to new species.
What are Variations and Mutations?
A factor that does not aid in the process of natural selection would be classified as ____________. (You must be prepared to defend your answer. Improper defense will result in no points given)
a. Overpopulation
b. Competition
c. Fossils
d. Variations
What is Fossils?
