Ready to dive into the past? What's the ultimate purpose of piecing together a phylogenetic tree?
To embark on a quest comparing the smarts of various creatures
To turn back the clock and pinpoint the age of different species
To map out species based on their global hideouts
To unravel the web of evolutionary connections among diverse species
Ready to dive into the fascinating world of evolution? Let's start with a bang! What's the very first piece of evidence for evolution and natural selection we're discussing today?
Direct observation
Microbiology
Genetic similarity
Structural evidence
Ready to dive deep into the past? What secrets does the fossil record reveal about the history of life on Earth?
The lack of common ancestry among species
Gradual changes in species over millions of years
The immutability of species over time
The sudden appearance of modern species
Why are lungs not considered a trait for the sea bass in the example?
Because it is extinct
Because it is an outgroup
Because it has gills instead
Because it lives in water
What does 'phylogenetic' mean?
Study of fossils
Study of genes
Related to the evolutionary history of groups of organisms
Study of animal behavior
What is considered an 'outgroup' in the context of phylogenetic trees?
A species that is the most recent common ancestor
A species that shares no common traits with the others
A species that shares all traits with the others

Which of the following is an example of natural selection?
Cricket frogs prefer to sleep during the day, while red-eyed tree frogs prefer to sleep during the night.
Pesticides are sprayed in a field, resulting in an increase in crop growth and a decrease in insect population.
Rabbits with a mutation for longer, thicker fur survive an unusually cold winter, while many normal rabbits do not survive.

What is a Scientific Theory?
An explanation that has a conflicting evidence
An explanation that is based on observation, experimentation, and reasoning.
A Guess (or hypothesis) of how an experiment will result.
A description that is an opinion. It is okay to disagree with it.
