In your own words, how would you describe the terms conditional probability and likelihood?
*
Why do we calculate likelihoods on a log scale?
*
How does the probability of transitioning from one character state to another (e.g., from A to T) change over time

You can use the Transition probability tool to explore this further.
*
What do we calculate using Felsenstein’s pruning algorithm?
*
Can you describe the gist of Felsenstein’s pruning algorithm? (optional)
