The letters outline the experiments Charles Darwin performed at the end of his life, to support his theory of evolution.

In a move that would have been unimaginable to the Victorian-age gentleman, the University of Cambridge is undertaking the largest-yet upload of letters to and from Charles Darwin. The university will post images of 1,200 letters online, including 300 letters that were previously unpublished.

The letters are between Darwin and his bff, botanist Joseph Dalton Hooker, with whom he worked out the theory of evolution, edited The Origin of Species, and talked about travel, literature, and family life. ("Did you administer the Chloroform?" Darwin asked Hooker upon hearing about the birth of Hooker's first daughter. Darwin was a fan of chloroform for both father and mother during births.) The two exchanged 1,400 letters over their lifetimes, making up 10 percent of Darwin's surviving correspondence.

The 300 new letters come from the end of Darwin's life and cover the experiments he conducted on evolution in plants and for his final book, The Formation of Vegetable Mold, through the Action of Worms.

The letters will appear on the Darwin Correspondence Project's Hooker page. I just tried to find some of the later letters, but they don't seem to be on the page yet. Nevertheless, there's plenty to explore. The Darwin Correspondence Project, the University of Cambridge project dedicated to Darwin's letters, has a top ten list Darwin-Hooker letters, including Darwin's first description to Hooker of his idea that species can change:

I was so struck with distribution of Galapagos organisms &c &c & with the character of the American fossil mammifers, &c &c that I determined to collect blindly every sort of fact, which cd bear any way on what are species.— I have read heaps of agricultural & horticultural books, & have never ceased collecting facts— At last gleams of light have come, & I am almost convinced (quite contrary to opinion I started with) that species are not (it is like confessing a murder) immutable. Heaven forfend me from Lamarck nonsense of a “tendency to progression” “adaptations from the slow willing of animals” &c,—but the conclusions I am led to are not widely different from his—though the means of change are wholly so— I think I have found out (here's presumption!) the simple way by which species become exquisitely adapted to various ends.

P.S. Can't get enough of scientists' old letters? Check out this list of "sins" Isaac Newton wrote that he committed in 1662.

Life on Earth originated as alien from space debris, over the course of time (yes evolution occurred), with the occasional spice of a visitor from above for the primate species to jump start and tweak our human DNA.

Anylcon, you say that with a ridiculous degree of certainty, when the scientific community would unanimously take exception to those claims. It must be nice, having mountains of incontrovertible direct evidence that the rest of the world apparently isn't aware of.

Tell me, how DO you know life started "as alien from space debris[sic]?" Were you carefully monitoring the chemical soup of the Earth billions of years ago, making sure that the chemical processes there would not result in life? Did you observe the barren planet suddenly flourish with microorganisms after a chunk of space rock struck the surface? If so, where is this rock which brought life to Earth, and how can you prove that it did, and it did not arise elsewhere?

And most importantly, what evidence do you have of "visitors from above?" Have you met them? Conversed with them? Obtained one of their spacecraft, or a picture of one at least? And what evidence have you found of genetic manipulation? I'm certain geneticists would love to hear precisely which chromosomes and gene sequences were altered. And while you're at it, could you also prove that said alterations could not have arisen naturally, in the case that you have no direct evidence that they were tampered with?

Go ahead, we're all anxiously waiting your answer.

Always defer to facts rather than speculation.

J. James,
Relax, have a tea..... Yes, I opinionated base upon life observation.

The wind blows and life on Earth gets mixed up. The cosmic winds blows and things get mixed up with the cosmos too.

Take care. ;)

Panspermia: Perhaps life did not begin on Earth at all, but was brought here from elsewhere in space, a notion known as panspermia. For instance, rocks regularly get blasted off Mars by cosmic impacts, and a number of Martian meteorites have been found on Earth that some researchers have controversially suggested brought microbes over here, potentially making us all Martians originally. Other scientists have even suggested that life might have hitchhiked on comets from other star systems.
........................

And later in the cosmic time, another life traveling in the cosmos came to Earth, older, wiser and tweak for their own reasons with the primate DNA, helping make modern primate humans.

.......................
So here we all are, lol.

Enjoy your tea!

"Religion is like a penis. It's fine to have one and it's fine to be proud of it, but please don't whip it out in public and start waving it around..."

@Robot, keep it in your pants.

@Democedes I had to laugh at that one. But if you appreciate your freedom of speech and freedom of religion then don't whine when someone else practices it, he's not yelling fire or anything.

Honestly its a little hypocritical.

democedes, take you own advice and never offer another opinion again on POPSCI... LOL.

Of course, I believe everyone has the right to their opinion. ~ in my opinion.

"Yes, I opinionated base upon life observation[sic]."

Is that supposed to mean something? Somehow I doubt that "observation" has passed rigorous peer review.

And yes, I am well aware of the THEORY of Panspermia. The problem with it is that there is no conclusive indication that it, and ONLY it, was responsible for life on Earth- after all, if it could happen on Mars, what in the world could prevent it from forming here of all places? It could theoretically be responsible for life on Earth, but it is far from a sure thing, and indeed is only ONE of very many competing explanations.

But the Theory of Panspermia is not the big claim here. It is your "visitors" and their supposed genetic modification of Humanity that most concerns me. Any proof of that, pray tell?

@democedes

I miss robot too

Next some brilliant scientist is going to tell us the Universe started from nothing and then turned into, well everything.

If you actually do your own research and investigate you'll quickly see that Evolution doesn't have any concrete facts to stand on.

trtp2,
If not evolution, what is left? POOF here we are!

Rather than POOF life began, I just imagine for a more likely theory in the great stew complexity and old age of the cosmos we Earth and all it's complexities did receive life else where from the cosmos.

I also find Darwin theory of evolution in the great time of the Earth likely too.

And as scientist speak currently of intelligent life existing now in the cosmos, I can easily imagine this type of intelligent life visiting Earth in the past and interpreted in religious ways around the Earth and culture. This visit happen in our past and yes tweaking with the local primates, making us humans.

No worries, you can still stay with your warm fuzzy theories that make you feel comfortable.
I cool with that!

April 2013: How It Works

For our annual How It Works issue, we break down everything from the massive Falcon Heavy rocket to a tiny DNA sequencer that connects to a USB port. We also take a look at an ambitious plan for faster-than-light travel and dive into the billion-dollar science of dog food.

Plus the latest Legos, Cadillac's plug-in hybrid, a tractor built for the apocalypse, and more.
