There are several reasons that the answer is highly educated may make you liberal, not the college experience per say! The conservative mantra that colleges are nothing more than evil liberal training grounds is a political move. It gives their base someone to hate for their plight, along with immigrants and people of color being the reason for all of the ills in life confronting them!

One of the reasons is, as you get more educated, you are introduced to a wider variety of cultures that you might have been afforded living in a microcosm before college. Your parent’s friends would tend to only be people who mirrored themselves! They would also tend to live in communities that also mirrored their belief system if possible. It is also true that high school students who are liberal tend to also go to college in much greater numbers! Hence a more liberal college population results! It has nothing to do with the college experience itself in that case.

Another possibility might be the growing numbers of women getting college degrees. Women, in general, tend to vote with the Democratic Party more than men. So as the population of highly educated people grew more female, that may have swung it left.

Third, the mainstream population that is conservative tends to be less educated! They do not tend to trend towards the highly educated or attend college, 31 percent of people with post-grad educations are consistently liberal, compared to 5 percent of those with high school educations or less according to the poll I saw! My own research tends to tell me this is factual even if the figures are not exact! Take that as you will, but it was not meant as any kind of detrimental slight! I myself have no college degree. I have gone to college a lot off and on, been to and graduated from several trade schools, let the military educate me to work on computer warfare aircraft in avionics, but basically, I am self-educated. I am liberal in case there was some doubt, but I have no formal college degree!

Yes, rich kids tend to be conservative also, and yes they tend to get educated, but they also tend to stay away from science-related pursuits! They tend to favor education that will help guarantee them a lifetime of successful avenues to get money and to keep it. Ok, not a sin, but you take a look at your GOP Senators, for example. A lot of lawyers, business majors, etc., you find not many scientists among them, no evolutionary biologists, no paleontologists, no teachers, you see where I am going. So you tend to only get a House or Senate with people of one mindset in that party. The other side of the aisle has a tendency to also come from that same background I freely admit that! You will find in the Democratic Party, however, more than a few with degrees in education, or science degrees, way more than you will in the GOP.

Also, if you are religious, especially those influenced by evangelicals, you will, even though highly educated, shy away from any form of study that makes you uncomfortable with what your Bible teaches! So we tend to have a lot of politicians who have absolutely no background in science as it makes them uncomfortable. It also makes them dangerous when it comes to being put in charge of entities whose whole being is based on science. NASA and the EPA are prime examples. You can talk about big government and over-regulation all you want, but big government is what you have right now under the current administration, and getting bigger and narrower in its scope and understanding every day!

These are a few ideas that have come out of this administration. Radiation is good for you, just like sunlight as long as it is moderate! Asbestos, one of our biggest killers, is safe! Dumping into streams and rivers is ok again! The clean air initiative is too extreme, so just get rid of it altogether. Oh, and let’s sue any state that still wants to make clean air a priority! Some GOP states have actually made mentioning climate change illegal; one has stated that you cannot connect rising sea level data to any study of climate change, even though their coastlines are in extreme danger! The white house has actually instructed that anything to do with climate change should just be ignored!
Is this really what you want? Sure the government is full of red tape and it is cumbersome and that does need to be fixed. But these cuts in protections all have one thing in common, a greater profit margin for big business and no concern for health issues. That cannot be the standard!

So, my point is, getting educated in itself tends to make you liberal, it is not that colleges are some kind of evil cabal indoctrinating our youth, they are just thinking for themselves, which has never been good for conservatives. Red states tend to be less educated with a poorer population on average! They also tend to be in need of more welfare than blue states, so why would they want to leave control in their state to the GOP whose leadership is responsible for the condition they find themselves in! Well, in this case, I say they are the ones being indoctrinated, why else would they vote against their own well-being!

I will not go into any moral issues I have with the President and the GOP, as they are more numerous than snowflakes in a blizzard! I just have to believe we will come to our senses at some point!

The Trail to Modern Humanity

Hybrid Neanderthal love child is found in a cave in Siberia: Teenage daughter of a Neanderthal mother and a Denisovan father who lived 50,000 years ago reveals how humans’ ape-like cousins frequently interbred!  

A prehistoric 13-year-old girl who lived 50,000 years ago was the love child of two separate species of ancient human ancestor, according to a new DNA analysis of her remains.

A study of a tiny bone fragment found in a cave in Russia shows the teenager had a Neanderthal mother and a Denisovan father, giving fresh insight into how the now-extinct species interacted.

The find suggests that our ape-like cousins mated far more frequently than researchers thought, according to archaeologists.

Neanderthals and Denisovans share a common ancestor with humans and roamed Eurasia as far back as 400,000 years ago having migrated from Africa.

The pair of human-like species then intermingled with modern humans when they arrived on the continent 40,000 years ago, with members of three species sometimes crossbreeding.

This means that tiny amounts of Neanderthal and Denisovan DNA can be found in our genome today! As much as 2% of our DNA was passed on to us from Neanderthals.

Research also shows that two modern genomes, one from Oceana and another from East Asia have distinct Denisovan ancestry.

“Previous studies that Neanderthals and Denisovans must have occasionally had children together,” said study coauthor Viviane Slon of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany.

“But I never thought we would be so lucky as to find an actual offspring of the two groups.”

Archaeologists came to their finding after sequencing the DNA of bone found in the Denisova Cave in Siberia’s Altai Mountains.

The ancient individual is only represented by a single fragment so small that researchers call it a ‘bone needle’.

‘The fragment is part of a long bone, and we can estimate that this individual was at least 13 years old,” said Dr. Bence Viola, an archaeologist at the University of Toronto who was not involved in the study.

After sequencing the genome of the young girl, scientists found she was the child of a Neanderthal mother and Denisovan father – putting her among the first specimens to show direct evidence the species mixed.

“An interesting aspect of this genome is that it allows us to learn things about two populations – the Neanderthals from the mother’s side, and the Denisovans from the father’s side,” said co-author Dr. Fabrizio Mafessoni.

Thousands of ancient hominin bones were uncovered in the Denisova Cave in 2012, including the 120,000-year-old toe bone of a Neanderthal and the first ever evidence of a Denisovan – the phalanx of a child who lived between 30,000 and 40,000 years ago.

It is commonly believed that a common ancestor of the two species migrated from Africa to Eurasia between 400,000 and 300,000 years ago and then split.

The traditional “Out of Africa” model suggests that modern humans evolved in Africa and then left in a single wave around 60,000 years ago.

The model often holds once modern humans left the continent, a brief period of interbreeding with Neanderthals occurred.

This explains why individuals of European and Asian heritage today still have ancient human DNA.

There are many theories as to what drove the downfall of the Neanderthals.

Experts have suggested that early humans may have carried tropical diseases with them from Africa that wiped out their ape-like cousins.

Others claim that plummeting temperatures due to climate change wiped out the Neanderthals.

The predominant theory is that early humans killed off the Neanderthal through competition for food and habitat.

How the story is changing in light of new research

Recent findings suggest that the ‘Out of Africa’ theory does not tell the full story of our ancestors.

Instead, multiple, smaller movements of humans out of Africa beginning 120,000 years ago were then followed by a major migration 60,000 years ago.

Most of our DNA is made up of this latter group, but the earlier migrations, also known as “dispersals”, are still evident.

This explains recent studies of early human remains which have been found in the far reaches of Asia dating back further than 60,000 years.

For example, H. sapiens remains have been found at multiple sites in southern and central China that have been dated to between 70,000 and 120,000 years ago.

Other recent finds show that modern humans reached Southeast Asia and Australia prior to 60,000 years ago.

Based on these studies, humans could not have come in a single wave from Africa around this time, studies have found.

Instead, the origin of man suggests that modern humans developed in multiple regions around the world.

The theory claims that groups of pre-human ancestors made their way out of Africa and spread across parts of Europe and the Middle East.

(I support the above hypothesis, as I have done other studies that support the multiple group theory! Opinion by John love)

From here the species developed into modern humans in several places at once.

The argument is by a new analysis of a 260,000-year-old skull found in Dali County in China’s Shaanxi Province.

The skull suggests that early humans migrated to Asia, where they evolved modern human traits and then moved back to Africa.
