Step 1: Allele Frequency Change
Read this first because it introduces the population-level view the rest of the path depends on.

Step 2: Hardy-Weinberg Equilibrium
Read this next to learn how a null model helps turn a pattern into a question instead of a premature conclusion.
Step 3: Genetic Drift
Read this third to see how chance alone can change a population and why not every increase implies selection.
What The Path Is Doing
Why this order is recommended
Begin with population thinking
The first steps establish that evolution is tracked in populations over generations, not in isolated organisms.
Then compare mechanisms
Once the population frame is clear, the path compares drift, selection, and mutation without collapsing them into one vague cause.
Then move to larger history
Speciation and common descent make more sense after the learner already understands how smaller population processes accumulate over time.

Reader-facing path file
The current path records the recommended order, assumptions, and what each concept unlocks next.
Didactopus derivative
The mentorship-oriented derivative adds session goals, openings, evidence focus, and transition cues.
Selection policy
The Notebook-side policy guides scaffold-record ranking without hard-coding Notebook-specific behavior into Didactopus.
Bundle-local export surface
The bundle-local manifest and status files say what counts as the current released Notebook surface for this path.
Notebook-wide export registry
The Notebook now publishes an export index so paths can be discovered as bundles instead of assuming a single hard-coded current surface.
