The Peppered Moth shows:

Natural selection due to environment

Harmful, beneficial, or neutral

True about geologic time scale:

Shows Earth history via fossils/rocks

A helpful mutation might:

Increase survival & reproduction

What does the fossil record primarily show us?

Patterns of life’s existence, diversity, and extinction

The geologic time scale is organized by:

Fossil discoveries and rock strata

On Wednesday
2
What affects trait frequency in populations?
Only human activity
Predator count
Sunlight
Reproduction and probability
3
The Peppered Moth shows:
Selective breeding
Gene mutation from UV
Artificial selection
Natural selection due to environment
4
Mutations can be:
Only harmful
Only neutral
Harmful, beneficial, or neutral
Only beneficial
5
Artificial vs. natural selection:
Faster in nature
Controlled by humans
Involves fossils
Doesn’t affect traits
6
Which supports common ancestry?
Tool use in animals
Similar fossils in all regions
Weather pattern changes
Similar DNA in whales and bats
7
What is NOT used in evolutionary reconstruction?
Anatomical structures
Fossil record
Genetic engineering
Embryological development
8
Rock layers help science how?
Track migration
Show fossil placement
Color observation
Measure water
9
Why might humans not intervene?
Species is harmful
Too many species
Too costly
Let nature run its course
10
Best for embryo comparison?
Habitat photos
Embryo development images
Adult skeletons
Food web diagrams
11
True about geologic time scale:
Covers only 1 million years
Shows Earth history via fossils/rocks
Has exact years
Predicts future species
12
A helpful mutation might:
Lower survival
Cause disease
Increase survival & reproduction
Be removed fast
13
What does the fossil record primarily show us?
Behavior of organisms
Patterns of life’s existence, diversity, and extinction
Exact ages of fossils
Types of soil in Earth’s history
14
The geologic time scale is organized by:
Sunlight amount
Human population growth
Fossil discoveries and rock strata
Atmospheric pressure
15
What changes gene frequency?
Stable weather
Natural selection
Cell division
Photosynthesis
16
Genetic engineering vs. breeding:
Takes longer
Involves fossils
Modifies genes directly
Not human-controlled
17
Which shows evolutionary relationship?
Living location
Camouflage ability
Similar limb bone structures
Different diets
18
What is a mutation?
A fossil measurement technique
A structural gene change on chromosomes
Species extinction
A behavior change
19
Trait inheritance is passed by:
Exercise
Genetics
Diet
Weather
20
Natural selection needs:
Fossil fuel use
Artificial breeding
Environmental change & gene variation
Diet & migration
21
Natural selection leads to:
Fossil increase
More mutations
Organism extinction
Trait change in populations
