Two New Studies Dig Into The Long, Curving Path That Cats Took Toward Domestication

Instead, the study suggests, domesticated cats flourished in China only by following the Silk Road, arriving there around 1,400 years ago. It’s also possible that climate change led to agricultural and population shifts in the region, possibly affecting how much food was available to the lurking Asian wildcats, the researchers suggest.

The paper published in Science, by contrast, focused on Europe and North Africa. It builds on previous work that had suggested the ancestors of domestic cats were a blend of Near Eastern and North African wildcats.

For the new research, the scientists analyzed samples of nuclear DNA—the main genome of an organism, containing both parents’ contributions—from the same specimens that were examined in the older study, which had not looked at this type of DNA.

Particularly intriguing was taking a new look at cats that lived in Turkey thousands of years ago. “I was so excited to have a look at their nuclear genomes for the first time,” says Marco De Martino, a paleogeneticist at the University of Rome Tor Vergata and co-author of the study.

Yet the new analysis suggested something dramatically different to the older work. These Neolithic felines were pure wildcat. The finding, similarly to the results of the analysis done in China, suggests that cat domestication unfolded much more slowly than scientists had thought.

“The cat is a complex species; they are independent,” says Claudio Ottoni, a paleogeneticist at the University of Rome Tor Vergata and another co-author of the Science study. “They were not just staying with humans—they would still go around and mix with local wildcats.”

Both findings suggest truly domesticated cats arose far later than previously believed—perhaps as late as 2,000 years ago. If that timeline is correct, it underscores just how rapidly cats have settled into the human world—and how much we have to learn about our feline friends.

What I've Been Reading

London is Tacoma before Tacoma is even a gleam in a Guggenheim’s eye. 
We pay attention to the wrong things. We make a mystery of Jack the Ripper. 
It’s not a mystery. It’s history.

Murderland: Crime and Bloodlust in the Time of Serial Killers by Caroline Fraser. 

Did anyone thought about asking this simple question of why there are less serial killers these days? Why?

Jessica Wolpaw Reyes was considering ideas for her PhD while worrying about lead paint since she was pregnant. She happened to listen to Steven D. Levitt's (of Freaknomics) talk. 

She narrowed down on the topic of "early childhood exposure and crime rate" in her dissertation (which was published in 2007). Her question became the seed for Fraser's brilliant book. 

This is yet another example of why it so important to meditate on why question to get at-least some of the causality behind a symptom. 

The most important question for us to ask now is - what is the x in 2025 compared to x = lead in 1950 to 1990 (almost 40 years time span)?

My answer is - consuming processed food, eating dead bodies from factory farming with horrible conditions and antibiotics, over eating sans fasting, plastic, cable news, talk radio, social media, cell phone, ecology collapse and living in concrete urban and sub-urban jungles, daily life sans biophilia and so on. 

Most reading this including myself will not be alive in 40 years if and when such a study comes out. 

One can wait for the next 4 decades or embrace precautionary principle now and avoid those potential mental and physical effects. Absence of evidence is not evidence of absence. 

Here's good excerpt from the book: 

According to Patterson, the average American during of age of leaded gasoline is so filthy when it comes to lead contamination that he's comparable to Pig Pen in the Peanuts comic strip. "Thats what people look like with respect to lead," he says. "Everyone. The lead from your hair, when you walk into a superclean laboratory like mine, will contaminate the whole damn laboratory. Just from your hair."

Not only that but Patterson calculates that the blood lead level of pre-industrial  humans would have have been 0.016 micrograms per deciliter, far lower than that of anyone living in the industrial age, American, he concludes, are suffering from "enough partial brain dysfunction, that their lives are being adversely affected by loss of mental acuity and irrationality. He devotes himself to campaigning against lead gasoline and to proving that everything Robert Kehoe ever said or upblished about "normal levels" of lead in blood is wrong.

The issue is currently its just not American's but the whole goddamn world is stuck in processed food, eating dead bodies from factory farming with horrible conditions and antibiotics, over eating sans fasting, plastic, cable news, talk radio, social media, cell phone, ecology collapse and living in concrete urban and sub-urban jungles, daily life sans biophilia and so on. 

Before even reading this book just last month I wrote

People who eat meat from factory farms pretending that nothing is going to happen to them is clearly a form of infallibilism.

I am not talking about the tragedy of commons in terms of moral and ecological consequences but their diet makes them live a parochial life, what thoughts they can think, how to live a good life, how to make better decisions for themselves and their families. 

In other words their diet makes their thinking and life stuck in a small rut of quagmire from which they cannot escape to realize the beauty of life right in front of their noses. Perhaps there are  thoughts we cannot think - in the spectrum of bandwidth of thoughts humans can think probably becomes even much smaller with their dietary choices which causes immense suffering. 

A much better payback happening here and now than some subjective future heaven and hell.

Take a moment and thank those men and women who fought so hard for decades to expose the effects of lead.  I bet "God" will appreciate that gulping dead bodies of Turkey.

Take a moment to identify the men and women are currently fighting to expose the cognitive and physical on human beings who are stuck in consuming processed food, eating dead bodies from factory farming with horrible conditions and antibiotics, over eating sans fasting, plastic, cable news, talk radio, social media, cell phone, ecology collapse and living in concrete urban and sub-urban jungles, daily life sans biophilia.
