Courses
See what you would learn
Understand how evolution actually works.
A course on evolution by natural selection, using everyday examples. It covers variation, selection and common ancestry, corrects the misconceptions most people carry, and shows why the theory explains so much about living things, including us.

Before the course is built
Setup asks about your situation first.
Lesson 1 opens on the moment you describe, and the examples use your role. For this request, expect questions like these.
- What is your starting point: a vague school memory, a firm grasp, or scepticism?
- What interests you most: human origins, animals, disease and resistance, or the mechanism itself?
- Is there a claim about evolution you have never been sure about?
Right for now
If any of this sounds familiar, start here.
Something about it never made sense
How eyes, or complexity, or purpose could arise without design.
It keeps coming up
Antibiotic resistance, pandemics and breeding all rest on it, and you would like the foundation.
Course arc
Where the course goes, in order.
Cadence writes the lessons for you, so the exact path follows your answers. This is the ground a course built from this sentence covers.
01 / 06Variation and inheritance
Where differences come from and how they pass on.
Selection
Why some variants spread and others vanish, without anyone choosing.
Common ancestry
The tree of life and the evidence for it, from fossils to DNA.
Complexity without design
How eyes and wings arise step by step.
Evolution happening now
Resistance, breeding and observed change in living populations.
Us
Human evolution, and what it does and does not explain about behaviour.
What changes
What you will be able to do, and what you will stop believing.
You will be able to
Explain the mechanism
Describe variation, inheritance and selection in your own words.
Correct the common errors
Recognise the misconceptions about progress, purpose and fitness.
See it operating now
Recognise evolution in resistance, breeding and disease.
Ideas this course corrects
Evolution has a direction toward progress
It has no direction. Fit means suited to a current environment, not better in any general sense.
Individuals evolve
Populations evolve. Individuals live and die with the traits they were born with.
Course questions
What to know before you start.
Is this a fixed course?
No. Cadence builds the course when you type the sentence and answer a few setup questions, so the lessons follow your situation. This page describes what a course built from this request covers. You see the whole path before Lesson 1.
Who is this course for?
A course on evolution by natural selection, using everyday examples. It covers variation, selection and common ancestry, corrects the misconceptions most people carry, and shows why the theory explains so much about living things, including us. It sits under Science & nature in the Ideas & discovery part of the library.
Do I need any prior experience?
No. Setup asks what you already know and where you want to use it, and the course starts from there. Bring a real situation if you have one; the examples are built around it.
How long does it take?
Courses run 7 to 30 lessons of about 10 minutes, sized to what you asked for. One lesson a day is the intended pace, and you can go faster. Lessons can be read or played as audio.
Does this course award a certificate or degree?
No. Cadence is for practical self-learning and does not award accredited degrees or professional certification.
