What type of fossil this?
Trace
Which mass extinction is known as the deadliest?
Permian-Triassic
What does "evolution" mean?
Change over time
Where (what environment) did the first forms of animals originate?
The ocean?
List 2 solutions that an individual could do to stop or slow the current 6th mass extinction
Will vary....recycle, educate yourself or others, use re-usable items, not plastic, advocate to local officials...
What types of fossils is these?
mold (C) & cast (D)
Which mass extinction does the KT boundary/ astroid theory belong to?
Cretaceous Tertiary
100 points = What is an inherited trait?
100 points = Give an example
a physical feature that is passed down from biological parent to offspring.
Examples will vary: eye color, hair color, height, nose shape, eye shape
Which came first, birds or mammals?
Mammals
According to the marine species graph, what happened to the population 250 MYA and present day?
The population increased
How can fossils provide evidence of evolution?
You can see how the organisms bones change over time and which species lived when based on the rock layer its found
This % of species must go extinct to be considered a mass extinction
70% (or more)
What is this photo an example of?
Variation
Think back to pocket mice activity: What caused the dark mice to survive better in the environment?
They had dark fur so they blended in better on newly covered dark rocks caused by a volcanic eruption
Which type of feature does each photo show?
Left = Homologous
Right = Analogous
Which fossil layer is the oldest? How do you know
The bottom green one, because it's at the bottom.The more recent fossils will be on top.
What do scientists believe the cause of the Triassic Juriassc extinction was?
Pangea & Volcanic Eruptions
What does speciation mean? Give an example.
A new species is created/ evolved from a previous one.
Ex: Amphibians from fish (or any other that evolved from a precious one)
Explain the difference between evolution & natural selection
Evolution is change over time...natural selection is survival of the fittest
Which type of structure tells us that organisms inherited a feature from a common ancestor?
Homologous Structures
Why are there no fossils in layer X?
This was during the time of a mass extinction
These 2 mass extinctions are categorized by having temperature decreases.
Ordovician-Silurian & Late Devonian
Explain Natural Selection. Include the words: fit, reproduce & trait.
Natural Selection is when the organisms that are most "fit" for the environment survive. Meaning the organisms that are easily able to get enough food/ resources & hide from predators will reproduce more and the organisms that are not able to do these things will die out. Therefore the organisms that are more fit will continue to reproduce & pass on their traits to their offspring and continue to thrive wile the other organisms will die out.
Recall 2 facts from any of the Evolution Newspaper articles...your classmates will fact check you
something they ate, feature they evolved during that time, what happened to make them have to change (what caused the evolution), an adaptation they had (giraffes grew longer necks to eat off tall trees)
Name the 5 ways Humans are contributing to the current 6th mass extinction
1. Rising CO2 levels
2. Habitat Destruction
3. Invasive Species
4. Pollution
5. Over Harvesting
