Unsettled Tree of Life

Is the science of evolution a settled story? Join us for a deep dive into the questions and challenges that scientists themselves are debating. We explore some of the most significant puzzles that are causing a growing number of researchers to call for a new theory of evolution.

In this video, we unpack:

The Origin of Life: Why the classic "primordial soup" theory is considered "past its expiration date" by some biochemists and the immense challenges of forming life's first complex molecules in water.

The Genetic Code: The staggering odds against forming a functional RNA molecule by chance (1 in 10^150) and the "chicken and egg" problem of needing proteins to read the very code that builds them.

The Fossil Record: How the "abrupt appearance" of animal body plans in events like the Cambrian Explosion challenges the idea of slow, gradual change that Darwin expected.

A Tangled Tree of Life: Why molecular biology has often failed to produce a single, consistent "tree of life," with different genes telling contradictory evolutionary stories.

Irreducible Complexity: A look at molecular machines like the bacterial flagellum, which require dozens of protein parts to be present at once to function, challenging a step-by-step evolutionary pathway.

Debunked Icons: How former evidence for evolution, like "vestigial organs" (e.g., the appendix) and "junk DNA," have been overturned by discoveries revealing their vital functions.

Puzzling Patterns: The challenge of "convergent evolution," where complex features like the camera eye appear independently multiple times, and biogeography, which sometimes relies on "highly improbable" scenarios like monkeys rafting across the Atlantic Ocean.

This isn't a debate from outside of science; it's a conversation happening among PhD scientists who are questioning if random mutation and natural selection can truly account for the full complexity of life. What do you think? Let us know in the comments below!
