Brief Introduction

After having his DNA analyzed through the National Geographic Society's Genographic Project, he developed an interest in genetics and genealogy that led him to do further research into the genetic history of the Indian subcontinent. As a result of this effort, his first book "Before India: Exploring Your Ancestry Through DNA," was published in 2014. In addition to being an author, David is the founder and president of a management services and communications firm where, among other things, he published a business journal on technology for fifteen years. Before starting his firm he held management positions at several multinational companies including Air India, Xerox Corporation, and a Howard Hughes company. David earned the advanced executive MBA degree from the Peter Drucker School of Management at Claremont Graduate University, the MS degree from University of Rochester, and the BA degree from Dominican College. He is an instructor at the University of California at Los Angeles (UCLA), and serves as a volunteer at the J. Paul Getty Museum in Los Angeles

Before India: Exploring Your Ancestry with DNA (2014)

Author: David G. Mahal

Publisher: DGM Associates

Before India is an easy-to-read guide to ancestry that focuses specifically on the Indian subcontinent. It illuminates how human origins and ancestry are best discovered through a combination of science and history. The book is not a dry study of genetics. It includes many appropriate pictures, maps, and charts to reinforce the text.

Mirroring a multifaceted subject matter, the book Before India is a fascinating, well-researched amalgamation of genres—part genealogical guide, part ethnic history, part science exposé—that draws a more holistic picture of ancestry by combining these varied insights. And while this easy-to-read text is a perfect launching point for people whose ancestry ties them to the Indian subcontinent, any reader will benefit from suggestions on how to trace your lineage to an ancestral group going back thousands of years.

Exploring topics such as the cosmos, the origin of our planet and human evolution, migrations and invasions to the Indian subcontinent that brought many different foreign genes, as well as how DNA science is used to trace ancestry, the book provides both a robust explanation of genealogy and penetrating insight into India’s colorful tapestry of hundreds of unique ethnic groups.

The book includes a research study of the ancestral origins of several key ethnic communities in India, Pakistan, Bangladesh, and Sri Lanka, along with some communities of Indian and Pakistani origin in a few other countries.

Review of the book: by Dr. Tim Barrett, Department for Continuing Education, Oxford University

Bringing together cosmology, genealogy, evolution, history and the story of the human genome, David Mahal's exploration of humankind's sense of belonging provides an accessible guide to the latest thinking on human genetic heritage ... the pleasure lies in the author's adept synthesis of diverse disciplines and in the provocative questions raised, not least the eternal importance of "where we come from" and of where that question now stands in the face of the DNA revolution. As Mahal demonstrates, current science promises a wholesale, sometimes startling reassessment of our roots and ancestry. Though the book's ultimate topic is the ethnicity of the Indian subcontinent there is much to enjoy, and learn, for all those interested in discovering their deeper family origins.

Ancestral Roots of the Jats:DNA Revelations (2015)

Author: David G. Mahal

Publisher: DGM Associates, ISBN-10: 0692369597, ISBN-13: 978-0692369593

The Jats represent an ethnic community that has inhabited the northwest region of the Indian subcontinent (both in India and Pakistan) for several thousand years. This book is about the ancient origins of these people long before history books were written.

The Jat community is estimated to equal the combined population of France, Spain, and Portugal. Many members of this community are now scattered all over the world, including Australia, Canada, United Kingdom, United States, and New Zealand. This book is a shorter version of Before India, and focuses specifically on this ethnic community.

Study on Origin and Diversity of the Jat Population

David G. Mahal and Ianis G. Matsoukas conducted studies on Y-STR Haplogroup Diversity in the Jat Population which Reveals Several Different Ancient Origins. A brief about this study is as under:

The Jats represent a large ethnic community that has inhabited the northwest region of India and Pakistan for several thousand years. It is estimated the community has a population of over 123 million people. Many historians and academics have asserted that the Jats are descendants of Aryans, Scythians, or other ancient people that arrived and lived in northern India at one time. Essentially, the specific origin of these people has remained a matter of contention for a long time.

This study demonstrated that the Origins of Jats can be clarified by identifying their Y-chromosome haplogroups and tracing their genetic markers on the Y-DNA haplogroup tree. A sample of 302 Y-chromosome haplotypes of Jats in India and Pakistan was analyzed. The results showed that the sample population had several different lines of ancestry and emerged from at least nine different geographical regions of the world. It also became evident that the Jats did not have a unique set of genes, but shared an underlying genetic unity with several other ethnic communities in the Indian subcontinent. A startling new assessment of the genetic ancient origins of these people was revealed with DNA science.

जाटों के पुरखों का इतिहास-डीएनए खुलासा

कैलिफ़ोर्निया विश्वविद्यालय लॉस एंजिल्स के प्रोफेसर डेविड जी. महल द्वारा लिखित जाटों के पुरखों का इतिहास-डीएनए खुलासा का हिंदी अनुवाद हम आप सब से साझा कर रहे हैं। यह पुस्तक जाट इतिहास पर अब तक लिखी गयी सभी किताबों से हटकर डीएनए के अध्ययन व परीक्षण पर आधारित है।

परोफेसर डेविड महल लिखते हैं 'कुछ हजारों साल पहले, जाटों ने शुरूआती हिंदू पंथ को अपना धर्म मान लिया था। क्योंकि तब हिंदु पंथ के ठेकेदारें ने जाटों की वैदिक सम्भयता को अपने धर्म ग्रंथो में मान्यता दी थी! बाद में, उनमें से कुछ बौद्ध और जैन हो गए थे।

इस्लाम के ग्यारहवीं शताब्दी के आसपास उत्तरी भारत में पहुंचने के बाद, इस नए धर्म इस्लाम को भी जाटों ने अपना लिया था।

पंद्रहवीं सदी में सिख धर्म की स्थापना के बाद, कुछ हिंदू और मुस्लिम जाटों ने इस नए सिख धर्म को अपना लिया था ।

पिछले एक हजार वर्षों के दौरान जाट तीन अलग-अलग धर्म आधारित समुदायों: हिंदू, मुस्लिम, और सिखों में बंट गए हैं। कई जाट अपने अलग धर्म के बावजूद अभी भी अपने परिवार के गोत्र सरनेम के रूप में प्रयोग करते हैं जैसे- मान, गिल, बाजवा, चीमा, खोखर, तरार (तरड), खोजा, पुनियां, डूडी, गोदारा, सारण इत्यादि।

प्रोफ़ेसर डेविड आगे लिखते हैं 'भारत और पाकिस्तान में सभी हिंदू, मुस्लिम और सिख जाटों की कुल आबादी का अनुमान 123 मिलियन लोगों के आसपास है। यह संख्या फ्रांस, स्पेन और पुर्तगाल की कुल आबादी के बराबर है।'

प्रो डेविड ने पंजाब और हरियाणा के जाटों के अलावा भारत और पाकिस्तान के विभिन्न जातीयों व समुदायों के डीएनए सर्वेक्षण कर अपनी पुस्तक में निष्कर्ष निकाला है। उनके पास जाटों के मुख्यत छ: हैप्लोग्रुप - ई, जी, जे, एल, क्यू और आर हैं। और उनके मार्कर्स हैं : एम-96, एम -201, एम-304, एम-11, एम-242, एम-207। इन हैप्लोग्रुप व मार्करस के नमूनों के आधार पर, उन्होंने जाटों की उत्पत्ति - साइबेरिया, रूस, कजाकसतान (उत्तर एशिया), मध्य एशिया व नारथन यूरोप- उज़बेकिस्तान, तुर्कमेनिस्तान, अजरबैजान, जर्मनी, युक्रेन, ईरान, ईराक़ व पशिचमी चीन तक (कैस्पियन सागर से पश्चिमी चीन के बोर्डर) पम्मीर नॉट क्षेत्र- ताजिकिस्तान, किरगिस्तान, अफ़ग़ानिस्तान (हिंदू कुश, तिआन शान, हिमालय), स्कैंडिनेवियाई - जर्मनी, स्वेडन, डेनमार्क, मध्य पूर्व के पूर्वी किनारे- तुर्की, सीरिया, जर्मनी और उपजाऊ क्रेसेंट- तुर्की, लेबनान, इज़रायल, जोरडन (मेसोपोटामिया, भूमि और टाइगरिस और यूफ्रेट्स नदियों के आसपास) को माना हैं।

नोट-कुछ मानसिक रोगी धर्म के पलड़े में जाट को तौलते है उन्हें समझ जाना चाहिए कि नस्ल असल है धर्म नकल है। धर्म और नस्ल में नस्ल हमेशा बड़ी होती है ।
