What is Your Favorite History Site - Open Comments

Over the years, I have become very protective of my comments. They have been targeted as prime spam space by many spammers and I still have to delete many spam submissions. One of the rules I enforce is that links to others sites almost always result in a deletion of the comment before it is published.

At the same time, I also realize that many people who comment have tried to share a valid good site here. With this in mind, I am going to make a one post exception and solicit reader comments on their favorote history site. Go ahead and on this one post make a link to your favorite history site.

A few notes:

1. Comments in this blog have a no follow tag on them. This means the search engines will not follow them. The site will get no Google PR juice. (If you do not know what this means, you are not in the search engine optimization field.)

2. Even in this open forum, I will not approve an obvious spam site. If it is not history related (or is too heavy on advertising), I will still deny the comment.

3. All comments must include a description of why the site is good. Failure to include this convincingly will result is a deletion as well.

4. You may comment on your own site as long as it is a good history site.

Have fun!

History of Nations - Africa

The History of Nations has a nice collection of African national histories up at History of Nations - Africa. A few of these are out-of-date by a few years. Others concentrate too much on recent history while neglecting most of the past. As a whole though, this is a good list with some good histories in it for anyone looking for some "Cliff Notes" on the history of an African nation. The articles appear to be a mix of public domain text from various sources with some original writing. (Hat tip to the Yahoo! Directory for this find.)

Here are a few entries:

-- Angola

-- Benin

All blue-eyed people share one common ancestor

I read with fascination a recent article from The Register titled All blue-eyed people share one common ancestor. As someone with blue eyes, it was nice to learn where my eyes came from in the first place. Professor Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen is the person behind a team working on this discovery.

I am quit pleased to learn that I am closely related to all the blue-eyed people on the planet. It is also nice to know now that I am a mutant that originated from a small gene change 6-10 thousand years ago!

From the article:

The proof that all blue-eyed people have a common ancestor comes from the fact that whereas eye colours ranging from brown to green are caused by relatively large differences in the amount of melanin in the iris, controlled by "considerable individual variation" in the area of the DNA responsible for melanin production, the variation in iris melanin levels across all blue-eyed individuals is very small.

Eiberg elaborated: “From this we can conclude that all blue-eyed individuals are linked to the same ancestor. They have all inherited the same switch at exactly the same spot in their DNA.”

Eiberg noted that the blue eyes mutation is neither "positive nor negative", since it doesn't affect chances of survival. He concluded: "It simply shows that nature is constantly shuffling the human genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so.”

History Carnival LXI

History Carnival LXI is now available at Histori i Media. For the first time, the History Carnival is hosted at a blog that is primarily in Polish. For those who do not speak or read Polish, this post is up in English.
