Question 2
2.
What rational environmental evidence do you have to support why the duck population changed over time?
CFS:
accurately describes the relationship between environmental changes and population variations
describes the cause and effect relationship between environmental factors and species traits
Dolphin Dorsal fin size
Large dorsal fins allow dolphins to swim faster and escape their predators.
Create a histogram that will explain the increased dorsal fin size.
Include the environmental changes that would make this shift possible.

Chapter 2: Natural Selection and Reproduction
Lesson 2.2: Survival and Reproduction
Observing Reproduction in the Sim
Consider the key concept: Individuals inherit their genes from their parents, and these genes determine their traits.
traits in a population are selectively chosen in a generation.
traits in a population are passed down from generation to generation
Part 2: Observing Reproduction in the Natural Selection Simulation
Goal: Gather evidence to support or refute the claim that ostrilopes with adaptive traits have more offspring than ostrilopes with non-adaptive traits.
Do:
Open the Natural Selection Simulation and open the mode: Reproduction Claims.
Reset in the Sim, select an ostrilope with another color trait from the table below, and press Play to repeat your observations.
Tip:
If the ostrilope dies before reproducing, record a 0 in the data table.

Question 5

Zoom into the environment in Build and select an ostrilope with one of the color traits in the table below.
Press RUN and count the number of times that ostrilope reproduces before dying.
Record that number in the data table below.

Claim: Ostrilopes with adaptive traits are more likely to reproduce than ostrilopes with non-adaptive traits.
Does the data from the entire class support or refute this claim?
