Introduction

Homeostasis

Lamarck

The Weismann Barrier

Biology's Second Law

This is a series of short video lectures intended to supplement a work in progress: my third book (working title: Biology's Second Law. Evolution, Purpose and Desire). This book is intended to round out the message I have been developing in my previous books: our current understanding of evolution is deeply flawed and incomplete.

Biology's Second Law

These are presented mostly in the order the argument is developed. We're putting up new ones as we progress, so check back often!

Introduction

The problem with biology today is we think we have a coherent theory of biology, but we don't. Homeostasis--biology's second law--can be the bridge to get us there.

Homeostasis

If homeostasis is Biology's Second Law, what's homeostasis? Our current conception of homeostasis is a pale imitation of Claude Bernard's original conception of it. To appreciate how profound an idea it is, we must define it properly, and clear away some of the misconceptions that have built up around it.

Lamarck

Lamarck, widely regarded as a misguided predecessor of Darwin, is one of the most misunderstood figures in biology. Here I try to set the record straight, for it is in the true understanding of Lamarck that the need for Biology's Second Law is justified.

The Weismann Barrier. The barrier that wasn't

The Weismann barrier-the doctrine of germline segregation developed by the German biologist August Weismann in the late 19th century-has long been regarded as the decisive disproof of the Lamarckian idea. New discoveries in molecular genetics are showing the Weismann barrier to be just the opposite of what it has long been thought to be. Rather than isolating the germline cells, the Weismann barrier is the active manager of epigenetic inheritance between soma and germline.
