One-stop shop to make India 20 times richer

Category: Science

Yes, so there were these so-called “Aryans” who migrated into India. The proof is now conclusive.

I have commented extensively on the “Aryan” migration theory over the years. My well-researched position has been that:

a) Archaeological evidence points 100 per cent to inflow of “foreign” migrants into India (e.g. see this blog post)

b) Linguistic evidence is overwhelmingly clear (100 per cent) that modern Indian languages (including Sanskrit) came to India from outside (e.g. see this post). Attempts to suggest that Sanskrit originated in India result in pure gibberish (e.g. see this post, this one, and this one [My analysis disproves the “Out of India” theory of the recent Hindutva fanatics]

c) DNA evidence has been relatively unclear so far but the science is very new and surely more will be learnt soon.

Now, even DNA evidence has become very clear. This article confirms it.

R1a is distributed all over Europe, Central Asia and South Asia; its sub-group Z282 is distributed only in Europe while another subgroup Z93 is distributed only in parts of Central Asia and South Asia; and three major subgroups of Z93 are distributed only in India, Pakistan, Afghanistan and the Himalayas. This clear picture of the distribution of R1a has finally put paid to an earlier hypothesis that this haplogroup perhaps originated in India and then spread outwards. This hypothesis was based on the erroneous assumption that R1a lineages in India had huge diversity compared to other regions, which could be indicative of its origin here. As Prof. Richards puts it, “the idea that R1a is very diverse in India, which was largely based on fuzzy microsatellite data, has been laid to rest” thanks to the arrival of large numbers of genomic Y-chromosome data.

QED. The proofs are ALL clear now.

But note that I use the word Aryan in quotes. That is because I do not consider that the idea of “Aryan” is robust or well-defined enough in any meaningful way. What exactly is it? A cultural idea, a linguistic idea, a “race” idea? No one can say for sure.

All we can say at best is that FOREIGNERS from Central Asia (including from as close as Iran) came into India.

Some of the things to measure in regular (annual) blood tests

I’ve been a bit careless over the past few years in monitoring my declining levels of Vitamin D in the body. That’s something I woke up only yesterday after randomly chancing upon a report which showed a strong correlation between low Vit D levels and prostate cancer. I studied a bit more and found many more studies.

Regular (annual) blood tests are absolutely critical. It is only through such tests that my prostate cancer has been picked up. Hopefully it has not spread – fingers crossed. (Note: Although I’ve been fairly regular about these tests, I was a bit slack last year – too many things happening around me – and I did not immediately see the specialist despite a referral  –  A strong warning I’ve received to not neglect tests and specialist referrals at any cost.)

Better to take preventative steps than to suffer from consequences of ignorance.

I measure the following regularly.


Vitamin D

A few years ago my Vit D levels had plummeted in to a severe deficiency stage.  Most dark-skinned knowledge workers across the world (including in India) have an extremely indoor style. Even my exercise is largely indoor – in a gym. This problem of low Vitamin D among office workers, particularly with a darker skin, is by now long documented. Btw, I don’t take milk or yogurt, either! A recipe for disaster.

Unfortunately, I was a bit careless. After reverting back my Vit. D levels to some semblance of normalcy after they had dropped precipitously, I did not continue taking the supplements regularly, since around 2013. (Took once in a while, but not regularly.) Because of that my levels declined steeply from 98 mmol/L in 2013 to 79 in 2014 and 59 in 2015 – a one way decline to levels below 50, which are considered deficient. More problematically, I suspect, this yo-yo level of Vit D is not healthy. I did not take a Vit D test in 2016 or 2017 but I’m sure the levels continued to decline – during a critical period for the development of my prostate cancer.

I’ve started taking Vit D again a few days ago. I feel a bit stupid about not having continued regularly supplements through out the past few years.


Fasting glucose is the key level to be tracked.


This measures Iron and related matters.


This measures cholesterol.

General chemistry

The main general chemistry test measures around 15 different types of chemical markers, such as sodium, potassium, urea, etc. etc.


I’m particularly interested in this protein marker which has significant predictive relationship with inflammation across the body and can predict potential heart issues.


This measures Haemoglobin and platelets, etc. It provides around 10-12 different results. I’m afraid I’ve not understood these very well, but endeavour to track anything that’s outside the normal range.


This is mainly about the Thyroid gland and tests TSH. However, there is also a crucial test:

Tumour marker – PSA

This is a test for prostate cancer and is recommended in men over 40.

Human evolution is SPEEDING UP RAPIDLY, and no, it has not come to an end

A friend said that human evolution has come to an end since selection pressures are no longer relevant.

Let’s look at the facts. It is evident that human evolution is rapidly speeding up.


1) More mutations than ever before: Because human population is much larger than ever before (from a mere 5000 or so 75,000 years ago), therefore there are vastly more mutations in the species than ever before. Numbers matter. Mutations led to “races”, with slight changes in biology over the past 100,000 years. These variations are likely to further increase.

2) Fitness: Selection pressures kill off or otherwise disable those genes (through infertility) that are not well adapted to the environment. These pressures have led to the evolution of lactose tolerant genes in cow herders, plague tolerant genes in most Europeans, and malaria tolerant genes in most Africans. Selection pressures
continue unabated in most parts of the world (mostly in the Third World – India, Africa, China) where hundreds of millions of people die from disease. The survivors are more likely to have protective mutations. Pressures of climate cannot be removed, either.

3) Sexual selection: In a crowded world, not everyone gets a chance to reproduce. The genes of those not found suitable are weeded out. Likewise, certain genes that promote desirable traits (e.g. IQ, “beauty” – often affected by fashion) are in demand. The human brain is probably the most affected by this – since smarter people are more in demand.

Note that all dogs are a kind of wolf that’s been super-rapidly bred by humans – in just a few thousand years. Likewise. one would expect various “breeds” of humans to evolve through sexual selection.

4) Cultural selection: Some cultures weed out those who don’t “obey”. I suspect that if North Korean genes are analysed, the children may now have subservenient genes, with those who had independent genes being slaughtered. So also in many “hardcore” Islamic societies. In addition, in those societies, the ultra-stupids are regularly weeded out through suicide bombing.

A few articles/ videos to clarify this. Click the links on red – these are articles.
Study shows humans are evolving faster than previously thought

At least 7% of human genes have undergone recent evolution. Some of the changes included the emergence of fair skin and blue eyes in northern Europe, greater resistance to malaria in some African populations and the appearance of a gene that allows lactose to be digested.

Fastest-evolving human gene linked to brain boost
They identified the rapidly evolving region of DNA – called human accelerated region 1 (HAR1)

Humans are still evolving—and we can watch it happen
Two studies presented at the Biology of Genomes meeting here last week show how our genomes have changed over centuries or decades, charting how since Roman times the British have evolved to be taller and fairer, and how just in the last generation the effect of a gene that favors cigarette smoking has dwindled in some groups. the human genome quickly responds to new conditions in subtle but meaningful ways, she says.

Our brain size is rapidly changing
The gene Microcephalin (MCPH1) regulates brain size and has evolved under strong positive selection in the human evolutionary lineage. We show that one genetic variant of Microcephalin in modern humans, which arose È37,000 years ago, increased in frequency too rapidly to be compatible with neutral drift. This indicates that it has spread under strong positive selection [Microcephalin, a Gene Regulating Brain Size, Continues to Evolve Adaptively in Humans – Science, 9 SEPTEMBER 2005]

Ian Stevenson, Brian Weiss, Roger Penrose, H. N. Banerjee – researchers of the “soul”

I think it is time to make note of these and related “researchers” and to provide initial comment on them. These (and similar) “scientists” keep popping up from time to time in discussions, and I’d like to at least devote a minute to these chaps – basically to rebut them.

Ian Stevenson (1918-2007) – at the Sceptics Dictionary

in hardly any of Stevenson’s cases did he become involved with children so young. In the 14 cases covered in this book, Stevenson was only involved with one when the child was only two years old. The others were all older: one child was three, three children were four, one was six and seven ranged in ages from 9 to 21 before he even met them! (Stevenson doesn’t tell us how old his fourteenth case was when he met the child.) So who knows what these children really remembered? [Source: Reasons to doubt reincarnation]

Reincarnation Research and Myths of Scientific Practice

Stevenson died in 2007 but has been succeeded at the University of Virginia by fellow psychiatrist Jim B. Tucker, who specialises in the investigation of Western cases. Another leading and scientifically hard-nosed expert of reincarnation research is the anthropologist James G. Matlock, currently a Research Fellow at the Parapsychology Foundation [Source]
