If You're Curious About These Questions...
You should listen to this audiobook
- Did you know that the most profound secrets of our evolutionary journey are hidden not in ancient fossils, but deep within our own DNA?
- Have you ever wondered why major biological innovations, like lungs and limbs, often appeared long before they were ever used for breathing or walking?
- What if the key to human complexity wasn't the creation of new genes, but a radical way of repurposing the ones we already had?

Key Takeaways from Some Assembly Required
- Discover why plants and animals don't develop entirely new traits, but instead repurpose old ones, such as fish possessing proto-lungs long before they ever walked on land.
- Learn how the study of embryos unlocks the secrets of evolution by showing how an organism's physical development can drastically change based on its surrounding environment.
- Understand the surprising origin of all vertebrates by tracing our ancestry back to the sea squirt, a simple creature that shaped human evolution by halting its own development early.
- Find out how microscopic DNA switches organize our genomes, and how tiny genetic malfunctions are responsible for major evolutionary leaps like the transition from fins to wings.
- Uncover how modern DNA analysis proves that the journey of evolution is not a straight path, but rather a fascinating history of biological accidents and genetic anomalies.

Some Assembly Required Summary & Overview
Some Assembly Required (2020) is an approachable account of the great transformations in the history of life. Paleontologist Neil Shubin started his career looking to fossils for the answers to life’s greatest questions – but with recent scientific advancements, he argues that studying DNA reveals more about the journey we took to become human.
