Two men born on the same day, both controversial in their time: Abraham Lincoln is the patron saint of America, while Charles Darwin has become a figure perhaps even more controversial than he was 100 years ago.
Ever since Darwin the tree has been the unifying principle for understanding the history of life on Earth. At its base is LUCA, the Last Universal Common Ancestor of all living things, and out of LUCA grows a trunk, which splits again and again to create a vast, bifurcating tree. Each branch represents a single species; branching points are where one species becomes two. Most branches eventually come to a dead end as species go extinct, but some reach right to the top - these are living species. The tree is thus a record of how every species that ever lived is related to all others right back to the origin of life.
For much of the past 150 years, biology has largely concerned itself with filling in the details of the tree. "For a long time the holy grail was to build a tree of life," says Eric Bapteste, an evolutionary biologist at the Pierre and Marie Curie University in Paris, France. A few years ago it looked as though the grail was within reach. But today the project lies in tatters, torn to pieces by an onslaught of negative evidence. Many biologists now argue that the tree concept is obsolete and needs to be discarded. "We have no evidence at all that the tree of life is a reality," says Bapteste. That bombshell has even persuaded some that our fundamental view of biology needs to change.
So what happened? In a nutshell, DNA. The discovery of the structure of DNA in 1953 opened up new vistas for evolutionary biology. Here, at last, was the very stuff of inheritance into which was surely written the history of life, if only we knew how to decode it. Thus was born the field of molecular evolution, and as techniques became available to read DNA sequences and those of other biomolecules such as RNA and proteins, its pioneers came to believe that it would provide proof positive of Darwin's tree of life. The basic idea was simple: the more closely related two species are (or the more recently their branches on the tree split), the more alike their DNA, RNA and protein sequences ought to be.
It started well. The first molecules to be sequenced were RNAs found in ribosomes, the cell's protein-making machines. In the 1970s, by comparing RNA sequences from various plants, animals and microorganisms, molecular biologists began to sketch the outlines of a tree. This led to, among other successes, the unexpected discovery of a previously unknown major branch of the tree of life, the unicellular archaea, which were previously thought to be bacteria.
By the mid-1980s there was great optimism that molecular techniques would finally reveal the universal tree of life in all its glory. Ironically, the opposite happened.
Tal Dagan and William Martin at the Heinrich Heine University in Düsseldorf, Germany, who pointed out that in numerical terms a core of 31 genes is almost insignificant, representing just 1 per cent of a typical bacterial genome and more like 0.1 per cent of an animal's. That hardly constitutes a mighty oak or even a feeble sapling - more like a tiny twig completely buried by a giant web. Dagan dubbed Bork's result "the tree of 1 per cent" and argued that the study inadvertently provided some of the best evidence yet that the tree-of-life concept was redundant (Genome Biology, vol 7, p 118).
But consider this: Charles Darwin and Abraham Lincoln were born in the same year, on the same day: Feb. 12, 1809.
Just a coincidence?
Which man has benefitted the world more?
A system exists now by which Arab Muslims -- the bidanes -- own black slaves, the haratines.[4] An estimated 90,000 black Mauritanians remain essentially enslaved to Arab/Berber owners.[5] The ruling bidanes (the name means literally white-skinned people) are descendants of the Sanhaja Berbers and Beni Hassan Arab tribes who emigrated to northwest Africa and present-day Western Sahara and Mauritania during the Middle Ages.[6] According to some estimates, up to 600,000 black Mauritanians, or 20% of the population, are still enslaved, many of them used as bonded labour.[7] Slavery in Mauritania was finally criminalized in August 2007.[8] Malouma Messoud, a former Muslim slave has explained her enslavement to a religious leader:

I can't help but think you have some sort of a grudge against Darwin himself, not just his work. Darwin the man was just trying to do his job-being a scientist. No "agenda"....just trying to figure some stuff out and publish it.

Despite years of research, we have not directly observed natural selection producing new species of say, finches, as Darwin believed it could.
We do, however, see natural selection fine-tuning finch populations to help them survive in a cursed world,
however I have not put all of my thinking out there yet as to how Darwin was wrong.
The triumph of social Darwinism can be seen everywhere
I personally do not see how Darwin has brought any good at all to mankind.
How does the Abolition of Slavery compare to the Theory of Evolution by natural selection?

Seriously, you can not be serious about the domestication of animals bit?
Lincoln's work was different. It centered on his interaction with man.
Darwins centered on his interaction with animals.
So yes...thier work was different, but they were nontheless peers. They both became famous for thier work. They both dedicated thier lives to the work they believed in. It is just this that seperates the two men.
The Cause they believed in!

yes, I am serious... although it doesn't show natural selection pressures, it does show evolution with man-made selection pressures imposed... some of the domestic animals are so far gone from their feral forms, that scientists aren't exactly sure what species they evolved from...

Darwins centered on his interaction with animals.
Darwin centered on his observations in nature to explain how species come into existence. This includes man...

Using this logic, you can also say that Lincoln and Jack the ripper were peers...
Well you are comical about the animal thing...LOL! You are really comapring a kiwi fruit to a pumkin seed!
And Abraham Lincoln was not a rapist.
Sorry,,,Jack was in his prime in 1888, Lincoln was born in 1809.One man was famous for good deeds and a lifetime of service to humanity. One man was infamous for his hatred of women and preversion!
While you are correct in stating that Lincoln was key in slavery abolishment in America...I can not help but think that other nations eventually took notice.

This is sheer ad homenim. Perhaps you could offer an actual argument up? instead of just trying to ridicule me?

Neither was Jack

Actually, Jack the ripper had a HUGE impact on victorian society. His killing spree actually grabbed the attention of the ruling class. It wasn't until his time in Wwhitechapel that the plight of the extreme "unfortunates" was brought to the attention of the people who could do something about it.
It was also the first time when a coroner leading an inquest, actually stretched his authority to include modus operandi, criminal profiling, and crime scene photography. Most people don't know this... but the "Kelly" murder was the first time in history that photographs were taken of a murder scene.
So, vast improvements in criminology, new ways of conducting investigations, relief for the "unfortunates" in Whitechapel... seems like Jack the Ripper might have done more good than you give him credit for.
Remember... It's not the duty of history to determine morality or right/wrong behavior... Its up to history to accurately reflect the facts.
It's the author who puts the bias, and the reader who applies the current moral zeitgeist to history.
Theories suggest that the victims first were strangled, in order to silence them, which may explain the reported lack of blood at the crime scenes. The removal of internal organs from three of the victims led some officials at the time of the murders to propose that the killer possessed anatomical or surgical knowledge.[

As you say...
"Lincoln's own words:"
"I will say then that I am not, nor ever have been in favor of bringing about in anyway the social and political equality of the white and black races - that I am not nor ever have been in favor of making voters or jurors of negroes, nor of qualifying them to hold office, nor to intermarry with white people; and I will say in addition to this that there is a physical difference between the white and black races which I believe will forever forbid the two races living together on terms of social and political equality. And inasmuch as they cannot so live, while they do remain together there must be the position of superior and inferior, and I as much as any other man am in favor of having the superior position assigned to the white race."

Because the killer's identity has never been confirmed, the legends surrounding the murders have become a combination of genuine historical research, folklore, and pseudohistory. Many authors, historians, and amateur detectives have proposed theories about the identity of the killer and his victims.

Yea whoever the slimeball was he did nothing for humanity.
But good of you to pcik one of the lowest slimeballs in history, and try to hold him up to Lincoln.
And like I said in my first or second post...you are a teacher in the school system? And we wonder what happened to the children?
With teachers like you who needs communism or socialism or any other ism!
