adaptation

What does survival of the fittest mean?

organisms best adapted to the environment will produce more offspring

What are the four main components of natural selection?

variation, heritability, overpopulation, differential fitness

How does variation in a population occur?

Random mutations

Describe disruptive selection.

Selection that favors both extreme type traits.

Describe directional selection.

Selection that favors extreme type traits.

Describe stabilizing selection.

selection that favors mid-type traits

Which organism is most closely related to the mouse? How do you know?

Lizard--it contains more of the same derived characteristics than the fish and salamander.

What makes a trait "heritable"?

It can be passed on from parents to offspring via DNA.

Define "fitness"

adaptations allow for organisms to survive and reproduce based on the environment in which they live

Provide an example of an adaptation.

giraffes have long necks to eat leaves from tall trees

What is natural selection?

process in which organisms better adapted to their environments are more likely to survive and reproduce offspring

Provide an example of a vestigial structure.

human tailbone, whale pelvis

Where are older fossils found?

Deep in Earth compared to newer fossils found at Earth's surface.

How does embryological evidence support Darwin's theory of evolution?

Organisms looked the same early in development and developed structural differences as they grew.

How does the fossil record provide evidence for evolution?

It shows gradual change in structures over time.

What is an analogous structure?

Structures with the same type of function but not a similar internal makeup (ex: insect wings vs bird wings)

How do the wings of a bat and the fin of a whale provide evidence for evolution?

These structures are homologous (same bone types) indicating that these organisms were related by a common ancestor.

Which organism is most distantly related to humans. How do you know?

hawk or frog--same number of DNA differences; squirrel has most similar DNA pattern

Which period occurred further back in Earth's history--Jurassic or Permian? EXPLAIN.

Jurassic--time gets more recent as you move down the time scale.

Put the categories that separate time into order from BIGGEST (most inclusive) to SMALLEST (least inclusive).

Eon, Era, Period

What is being shown in the image?

Geologic Time Scale

What types of advantages do birds with large beaks have over birds with smaller beaks?

stronger for cracking seeds/ breaking into food source

Provide an example of variation in a population of butterflies might vary.

wing shape, size, pattern, etc.

Provide an example for how species vary over time.

Species that have gone extinct resemble species currently living today.

Provide an example for how species vary globally.

Organisms with similar features are found in similar environments across the globe.

Provide an example for how species vary locally.

Finches living close together have different sized beaks because they live in different habitats.

During his travels, what did Darwin notice about variation among organisms? (3 ways species vary)

global, local, over time

Darwin's Theory of Evolution focuses on the idea that organisms are all related to a common ancestor. Explain how a cladogram shows this.

At the base of a cladogram is a common ancestor. As characteristics arise over time, they are listed BEFORE the species that have them.

Turtles that lived on the Galapagos islands have different neck lengths. Why did this variation exist?

Turtles lived in different habitats and had features that allowed for them to access food available.
