I have had much to little time to get going with this blog. So what will I "start" with in this non introductory second post (I'm thinking as i'm writing)?

Ok, lets take an easy subject like human evolution. I'm not interested in the creationist debate on this matter since that is really a non-debate in my world - sort of a quarrel between people with a scientific viewpoint on the matter and people who wishes to align reality according to their beliefs. I don't really look down on the creationists in a genereal sense because I a realize how important faith can be in people's lives (the believers are the fittest right now from the standpoint of genetic survival) but it is a non-debate for me. I am an atheist but that's not the reason. The important thing for me in a positivistic debate is that both sides want to find out the truth with the help of logical thinking and empirical facts and that they are ready to change their viewpoints if the facts change.


However one thing (among many) that interests me about human evolution, especially rather recent evolution (last 40-50000 years), is it's speed. I happen to believe that many genetic scientists and interested laymen (most) have a sped up view on evolution that is not correct. Though I have to qualify that a bit. There has been a discussion about whether the evolution has had the same speed over the ages or whether it has sped up or slowed down. To me it has always seemed logical that more people means more mutations per time unit and thereby quicker evolution. This has not been evident to many. However inspite of this I believe that most "people" (often the same) at the same time have overestimated the speed of human evolution during the last 40 000 years.



Many of these people namely seem to believe that broader ethnicities or really genetic clusters like for instance "northern europeans", "southern europeans" and middle-easterners have developed since the last glacial maximum due to for instance the climatic conditions where they stayed put during most of this time. The bearers of the haplogroups descendning from IJK (It should have a new name now) evolved into these above mentioned groups due to the forces of nature, food sources and sexual selection etc.

However I belive that the cro-magnons who lived in europe 40000 years ago were very close to todays northern europeans genetically, especially those northern europeans who look a bit more "archaic" (I lay no value judgment in that description). Though with archaic I don't mean big, muscular and aggressive looking. I realize that the picture is probably complex with various groups but lets put it this way, I believe that one very important cro-magnoid type was short stubby and with a mild, melancholic and even sad expression.

Let me illustrate this description with a picture of 26000 year old ivory head found in central europe which might have been the top of a walking stick.

By the way if anyone owns the pictures that I post in this blogpost and disagrees to me using them I will take them down if you contact me.






To me this looks very northern european. Not like the nordic stereotype with chiseled features but like a more "archaic" (excuse me) and less known type. Can i muster any living examples of this type? Well how about these three swedish celebs.



1. Tomas Brolin (footballplayer in the national team during the 90s):






2.Mats Näslund (ice-hockey player during the 80s-90s)







3. Bert Karlsson (Record boss and entrepreneur catering to the "common people").







I also think it resembles this widely spread image of a cro magnon skull:





The main reason for different europid genetic clusters is instead according to my analysis, admixture with non europid groups such as ancestral south indians (andamanese and nicobarese), east africans, west africans, proto-native americans (the non europid side - pretty similar in the larger perspective to the ancestral south indians and proto asians according to my theory - though they might have been seperated for tens of thousands of years) etc.


However I have to state here that eventhough I believe that stereotypical northern/northwestern europeans are less admixed than other europid groups I think it's very possible that the progressive northern europid groups arose due to some admixture with non europid groups.



There is an instinct among many humans preferring their ancestors to have been exporters of genes rather than importers. This is of course not true for all individuals but claiming one's own ancestors to be more "pure" (another word that carries some weight, lets say a longer time of evolution without "foreign"/exotic genetic input) can easily be interpreted as some wishful thinking, childish bragging or a way to put down other groups of peoples.

Personally I believe myself to have some non-europid ancestry. Not recent admixture from 100% non-europids but from ancestors who are not 100% europid and I believe this to be the case with the overwhelming majority of northern europeans.

Let me end this post by saying that it might be a mistake to combine genes, culture, history and politics (and more subjects covered here that couldn't fit in the title) in the same blog since some people might think that politics are involoved when I discuss a non political issue. However that is definitely not my intention. I of course realize that no one is completely objective when it comes to choosing topics and intrepreting them but I will really strive to put politics out of the non political topics - if I don't see interesting paralells and possibilities for cross-fertilization, but then I will do so openly. Such possibilities as well as convenience is also the main reasons for me not streamlining the blog.

By the way, my politics, which I haven't discussed are not clear cut and I'm not superconfident about my views. I see politics as a balancing act. Trying to stay on the golden path (one's own - not necessarily the middle of the road in one's society) between less beneficial extremes but at the same time keeping an open mind and realizing that there are many golden paths.
