On the Origin of Species: On November 24, 1859, "On the Origin of Species" was published. To say that it made a splash would be an understatement. It changed the world. by Evolution Talk

The Beginning: Cyanobacteria: 3.5 billion years ago microbial organisms appeared on the earth. These organisms combined, split, and combined some more, until the formation of microbes and single-celled algae. One of these single-celled algae-like organisms were cyanobacteria. by Evolution Talk

Darwin On The HMS Beagle: Charles Darwin, at 22, had never sailed before. With his notebooks, gear, rifles, and trunks loaded, he stood on the deck of the HMS Beagle to bid England farewell. The date was 12/27/1831. by Evolution Talk

Hutton’s Hypothesis: James Hutton saw the power of natural selection, but he didn’t see how it could eventually, over vast spans of time, mold an animal into something completely different. That would have to wait until Charles Darwin entered the scene over 50 years later. by Evolution Talk

Unlucky Lamarck: Jean Baptiste Lamarck's mechanism for evolution was wrong, as history shows, and that fact has haunted his memory ever since. But ideas and theories have ways of being resurrected and, in recent years, there are hints out there that Lamarck wasn’t... by Evolution Talk

The Beginning: Life: In the beginning the Earth wasn’t exactly a hospitable place. It was hot, volcanic, and oxygen was a rare commodity. So the question now is how did life emerge from these conditions? We are still asking this 4.6 billion years later. Darwin proposed... by Evolution Talk

The Beginning: An Arms Race: As predators evolved to better catch their prey, their prey evolved unique and efficient ways to avoid being eaten. It was because of this sudden arms race that we see the proliferation of body forms that mark the Cambrian Era. The real winners were... by Evolution Talk

Why Darwin Matters: Over the last 150 plus years there is one subject which has caused its advocates and detractors to butt heads, often with incredulity at their opponents stance, and sometimes with animosity. That subject of course is evolution by natural selection.... by Evolution Talk

The Beginning: Sexual Reproduction: One day, millions of years ago, something occurred between two unsuspecting eukaryotes. When they bumped into one another something magical happened.

Introducing Evolution Talk!: If you've ever wondered what all of the fuss was about, or how evolution works, then you've come to the right place. Over the next few weeks, months, and years, we will look at Darwin's revolutionary theory and what it means to the life we see around us. by Evolution Talk

Mistakes Were Made: In the X-Men movies the X-Men are mutants. Mistakes were made during DNA replications that brought out features and abilities which were not present in the population prior to their births. Defects which enhanced their chances of survival. by Evolution Talk

Only A Theory: Charles Darwin had a hypothesis was that animals evolved due to a process he called natural selection. He strengthened his hypothesis with tests and observation. Evolution by natural selection has held up to every test. It is because of this that it... by Evolution Talk

Where Are the Dinosaurs?: What killed off the dinosaurs? There are many competing theories yet there is no ‘smoking gun’. There is evidence however, and with each bit of evidence comes another theory. Dinosaurs didn’t disappear overnight. It took a few millions years for... by Evolution Talk

Diderot’s Dream – Updated: Diderot devoured the written word. It was food for his mind and he couldn’t get enough of it. He was ravenous when it came to ideas. Especially when those ideas took him into places that others feared to tread. by Evolution Talk

Of Mermaids and Men: Benoit de Maillet believed that life, all life, came from the sea. And not only did it come from the sea, but it continued to evolve into different species as it encountered different environments. To present these ideas would be dangerous to him so... by Evolution Talk

Darwin’s Doubts: Throughout his life Charles Darwin suffered bouts of anxiety and often went off alone by himself to think. His work afforded him the perfect escape and he dove into it at every opportunity. by Evolution Talk

The Beginning: Multicellularity Rules: The reason natural selection had such a grand old-time with multicellular organisms is because it gave it something to select for. These organisms increased in size, moved into new areas for food, and protected themselves against the environment. It... by Evolution Talk

Erasmus Darwin: Erasmus was a country physician. He believed that women should have access to the same education that men did, and that slavery should be abolished. He also believed that life evolved from a single filament that wiggled out of the mud in the distant past. by Evolution Talk

Darwin or Design: As a young man, the more Charles Darwin learned about nature the more he began to question things. If species were immutable, meaning they never changed, then how was it that breeders were able to change the forms of dogs or pigeons? What if something... by Evolution Talk

The Missing Link: Darwin himself never used the term ‘missing link’. He wasn't concerned with a missing link but he was concerned with gaps in the fossil record. It wasn’t that he thought these gaps hurt his theory. So where did this term come from and why is it... by Evolution Talk
