2/ WE ALL CAME OUT FROM AFRICA, BUT SOME WERE HERE BEFORE OTHERS. SANSKRIT CAME AFTER TAMIL.

South Asia is one of the most diverse places on earth, with many hundreds of languages, reflecting great human diversity, and there is great genetic diversity as well. One of the
3/ things that we see when we look at genetic data from diverse people in India is that the great majority of groups in India, but by no means all groups, speak Indo-European and Dravidian languages. These are the two largest language families in India, and which are genetically
4/ well described as being arrayed on a gradient of different proportions of ancestry, different proportions of inheritance, from two very different ancestral populations, as different from each other as Europeans and East Asians. We have known for 11 years in India with this
5/ gradient of different proportions of these two highly divergent ancestries.

This came out of the work that we did in collaboration with K. Thangaraj in Hyderabad’s Centre for Cellular and Molecular Biology [CCMB]. We spent a lot of time over the past decade, trying to
6/ understand the origin of this major gradient of ancestry in South Asia that accounts for almost all of the ancestry in people speaking Indo-European and Dravidian languages, but does not account for unique and special ancestry that is common in people speaking Austro-Asiatic
7/ and Burmese languages. So most of the work we have done is focussed on that gradient. I’m happy to tell you what we have learned in the last decade about the origin of that group.

23rd September 2020.

Dr. Rajan Sharma,
President,
Indian Medical Association,

Dear Dr. Rajan Sharma,
It is with extreme distress that citizens like me note the very high death rate among doctors attending to patients in the current pandemic situation.

As per media reports and a statement attributed to your association about 382 doctors have lost their lives. I am sure
an equal or even larger number of paramedical staff, nurses and all those who work in hospitals too must have lost their lives. We, the citizens of the country, have read and watched social media videos, where doctors who have been at the forefront of this battle of

Shameless fellows. The BJP is holding talks with a jailed convict for a political alliance. This is the party allegedly led by an incorruptible leader!

"

TALKS are on for merger of the rebel faction led by V K Sasikala into the AIADMK, with the BJP facilitating the discussions, in preparation for the May 2021 Assembly elections. Two days ago, T T V Dhinakaran, who is running
the Amma Makkal Munnetra Kazhagam (AMMK) in the absence of the jailed Sasikala, travelled to Delhi, where he is said to have met top BJP leaders."

THE CURSE OF 24X7 TELEVISION NEWS. NIGHTLY COCKFIGHTS INSTEAD OF REASONED DEBATE AND DISCUSSION.

In his seminal study “Understanding Media: The Extensions of Man” Marshal McLuhan, the new age’s first media prophet proposed that: “a medium itself, not the
2/ content it carries, should now be the focus of study’’. He said that a medium affects the society in which it plays a role not only by the content delivered over the medium, but also by the characteristics of the medium itself. India now has over 167 million households (out
3/ of 234 million) with television sets, of which over 161 million have access to Cable TV or Satellite TV, including 84 million households which are DTH subscribers. Digital TV households have grown by 32% since 2013 due to migration from terrestrial and analog broadcasts.
