Genomic study of Indian populations finds five distinct ancestral components

Genomic study of Indian populations finds five distinct ancestral components | Teacher Tools and Tips | Scoop.it
(Phys.org)—A trio of researchers with the National Institute of BioMedical Genomics, in India has found via genetic study, five distinct ancestral components for the people of India.

 

The team reports that their study revealed that the four ancestral groups they found included what they describe as people of north and south Indian ancestries, people of Austro-Asiatic descent and people with Tibeto-Burman ancestries. Those from the islands were found to share genes with present-day Pacific Islanders. They also found evidence of the first Indians coming from Africa—another later wave of people came to the area from East and South Central Asia. They also found that the earliest people tended to intermingle for many years, sharing their genes across lineages, but that came to halt approximately 70 generations ago, which equated to approximately 1,575 years ago—the time period of the Gupta emperors, when the caste system was begun. Intermingling between the upper and lower castes diminished to the point that it could be seen in the genes of people alive today.

 

 

The researchers note that their study has revealed that Indian ancestry is far more genetically diverse than has been thought and also point out that they have shown that shifts in societal practices can lead to changes in the genomes of the people that live there, over many generations.

We Fact-Checked Snapple's 'Real Facts'

We Fact-Checked Snapple's 'Real Facts' | Teacher Tools and Tips | Scoop.it

Since 2002, the tea maker has been slinging bottle-cap factoids. Some are true, some are outright false, and plenty others are incomplete or ambiguous to the point of absurdity. But it’s easy to pluck out the spurious ones with a search engine and the right kind of bull**** detector.

 

With 30 seconds and a web connection, you can, too.

Sharrock's insight:

This might be fun for secondary schoo students to explore what is passed on as facts. Students can learn first-hand why we can't believe everything we read. This would make a simple but powerful library/research skills activity. Other subjects can exploit this as well.

Do I just Google that? Tools for Teaching Search Skills in the Primary Classroom « ICT for Teaching & Learning in Falkirk Primary Schools | Teacher Tools and Tips | Scoop.it

Nowadays many pupils, when given a research task, immediately might think to themselves, “I’ll just Google that.” Internet search engines are powerful tools but many pupils use only a fraction of the power of them, and then can also have difficulty finding the information specific to the task. There are many resources now available to help in developing pupil skills in searching more effectively using online search engines.

BPS Research Digest: As soon as they can read, children trust text instructions over spoken information

BPS Research Digest: As soon as they can read, children trust text instructions over spoken information | Teacher Tools and Tips | Scoop.it

Corriveau's team said their results showed that once children learn to read, "they rapidly come to regard the written word as a particularly authoritative source of information about how to act in the world." They added that in some ways this result is difficult to explain. Young readers are exposed to a good deal of fantasy and fiction in written form, so why should they be so trusting of written instruction? Perhaps they are used to seeing adults act on the basis of written information - such as maps, menus, and recipes - but then again, pre-readers will also have had such experiences. This suggests there's something special about the process of learning to read that leads children to perceive written instruction as authoritative.

Sharrock's insight:

Nexum reports in http://www.slaw.ca/2013/10/18/less-serious-legal-research/: ; "In addition to necessary and unnecessary complexity and jargon, there is one more reason why legal documents are boring: they are exclusively textual which is not as fun and self-explanatory as graphics and images. The power of visual communication has long been exploited by other “boring” disciplines. The field of open data often emerges as a naturalplayground for visual applications. Visualization experiments are not recent at all as witnesses this article from 2007. Some readers may even remember data visualization efforts dating back to the nineties."
