Around 300,000 years ago modern humans or Homo Sapiens emerged in Africa - a new human species distinct from the ancient human/ species such as Homo Erectus, Neanderthals, Denisovans and others who were here before us. The book first tells us how the world got populated with modern humans, then goes into detail about our ancestors in the Indian subcontinent and their links to the current population i.e. with all of us, providing evidence and tantalizing perspectives on who we are and how we came to be.
Three major prehistoric
global migrations spread modern humans across the
world. It was the Out
of Africa migrations that began this
spread circa 70,000 years ago when a small band of people migrated out of
Africa. In the millennia between 70,000 years ago and 16,000’ years ago, these few hundred people and their descendants populated the entire world. A
glacial period between 29,000 years ago and 12,000 years ago made migrations
almost impossible resulting in groups of migrants getting isolated from each
other in different regions. This led to genetic mutations in populations adapting
to climatic and other conditions of particular regions. Although these
differences (e.g. racial features) seem stark to us, in reality they are small
compared to what is genetically common across Homo Sapiens.
Neolithic
or farming related migrations
began around 12,000 years ago when the earth began warming up again. Modern
humans experimented with agriculture in different parts of the world. As
agriculture progressed populations increased significantly followed by more
migrations. Around
3000 years ago nomadic pastoralists - the Yamnaya people - from the Eurasian
Steppe region (present day Ukraine to Southern Russia to Western Kazakhstan)
migrated to Europe, and a millennium later to South Asia, spreading their
language and leaving their genetic mark on a large area of the world. Three
technological innovations - the wheel, the wagon and (domestication of) the
horse - that these nomadic people used, to carry water and supplies as they
traversed the vast steppe region, shaped their role in history. This was the Steppe
Migrations or Bronze Age migrations.
When
modern humans figured out how to cross oceans, especially in steamships, it led
to the colonial era. This set of Medieval Migrations (Colonial
migrations) had a tremendous global impact. In continents such as
Australia, America, colonial migrations greatly altered the demographic
composition of existing populations.
Four
major migrations over several millennia went on to make the population of
present-day India. The migrants who moved out of the African continent around
70,000 years ago and populated the world, reached the Indian subcontinent about
65,000 years ago. They are the First Indians. They reached
different parts of the subcontinent at different periods of time. By 20,000
years ago scientists believe India was the most populated region in the world -
a world record we still hold!
Between
12,000 and 8000 years ago a population related to early farmers and herders
from Iran, especially from around the Zagros Mountain area, reached the
subcontinent (likely close to Mehrgarh in present day Baluchistan) and mixed
with the first Indians living there. This mixed population of hunter-gatherers-herders
went on to develop agriculture. Over the next 5000 years this region and its first
farmers grew into the Harappan or Indus Valley civilization,
believed to be the largest civilization of its time with a seven hundred yearlong
mature phase marked from 2600 BCE to 1900 BCE. At its peak the civilization
covered much of present-day Pakistan, North-Eastern Afghanistan and Western
India. When the civilization began to decline due to long drought the Harappans
moved out both to the East and to the South.
Around
2000 BCE, after the agricultural revolution in China, migrants originating from
there crossed into South-east Asia and India. These Austroasiatic and
Tibeto Burmese Language speakers brought with them new agricultural
practices and the Austronesian languages. In India these languages are still
spoken by groups like the Santhal, Mundari, Ho, Khasi people as well as northeastern and Himalayan
groups such as the Bodo, Garo, and Meitei (Manipuri).
The
last set of migrants into the Indian subcontinent were the pastoralists – the Arya
- from the central Asian Steppe (approximately present-day Kazakh steppe) who
came in multiple waves between 2000 BCE and 1500 BCE, bringing with them
Indo-European languages as well as new cultural and religious practices.
The mixing between all these populations that
were in the Indian subcontinent by 1500 BCE was such that every population
group in present-day India (with the exception of the Andaman islanders)
carries mixed ancestry in varying proportions.
For me reading ‘Early Indians’ was as
fascinating as it was intense. The content IS complex! Not recommended if you
are in the mood for something quick or easy! Timescales are epochs where a
millennium is a mere moment in time. The landscapes of geography and climatic
changes traversed in less than 300 pages is mind boggling. Yet as I travelled
through the pages I could conjure up riveting scenes in my mind - of
prehistoric humans braving through hostile lands.
Tony Joseph’s writing is simple yet lucid,
straightforward yet compelling, sometimes provocative. He makes the complicated
story of Indians accessible to the reader. He presents evidence from several
fields of scientific enquiry – archaeology, linguistics and philology (study of
history of languages), ancient texts and importantly recent studies of ancient
genes.
I
found the arrangement of the book’s content helpful - although
I still had to re-read some portions, go back to an earlier page or chapter to
check a reference to wrap my head around some aspects. The book starts with a chronology
of modern humans in Indian prehistory, then Introduction to explain context,
followed by four chapters on the making of "Indians", an epilogue as "subjective
commentary" on the book's content. The Appendix, Summary and Frequently
Asked Questions sections reiterate key points from the book which helps to recollect
and retain.
At a time when the issue of migrants dominates
politics around the globe, reading “Early Indians” makes you see the world and
its people anew.
