I know Indians and East Asians share this haplotype M but the two diverged (seprated) some 40,000 years ago. The AFricans do not belong to this haplootype as far as I know. The only others who share this are some of the Central Asians. The female ancestor(s) of most Indian people were proto-Asian.
Anyway, we (all humans) are connected someway. Africans migrated out only 60,000 years ago, which is relatively recently, if you think about it.
My understanding is that Indians are ancestral to both Europeans and East Asians after they migrated out of India long time ago. But some were to later return back to India in the form of Dravidians, later others from Central Asia (so-called Aryans around 10,000 years ago) and others from Asia through the Northeast.
If you look at genetic mapping of the world's populations, Indians fall in between Europeans and Asians. The upper and middle castes are quite close to Euroepans while the lower castes are about intermediary and the tribals are closer to Asians than they are to Europeans.
There is an excellent lecture on this and shows Indians are very distant to Africans, more distant than Euroepans are.http://www.youtube.com/watch?v=ZPnLTmJfUu0
According to wikipedia.It says that the ethopians and egyptians belong haplogroup M1(ranging 17-20%) and found mostly in lower frequencies from all north africa to east africa,and very rare in middle east. Theres two hyphothesis origin of M,being either african or asian origin. While the decendant of M is decendant of L3, the M haplogroup could have mutated in asia.
From wikipedia: an african origin hypothesis
"The timing of the proposed migration of M1 and U6-carrying peoples from West Asia to Africa (between 40,000 to 45,000 ybp) is also supported by the fact that it coincides with changes in climatic conditions that reduced the desert areas of North Africa,"
From wikipedia: an asian origin hypothesis
"Haplogroup M1 has a restricted geographic distribution in Africa, being found mainly in North Africans and East Africa at low or moderate frequencies. If M had originated in Africa around before the Out of Africa migration, it would be expected to have a more widespread distribution"
This is what I got from wikipedia. It seems that africans,australoids(adamans,semangs ect), south asians( indians,pakistani,bengali ect) and east asians and south asians belong to a different macrohaplogroup M lineages
Haplogroup M1  - found in North Africa, Horn of Africa, Mediterranean, and Middle East
Haplogroup M2  - found in South Asia, with highest concentrations in SE India and Bangladesh; oldest haplogroup M lineage on the Indian sub-continent.
M2a - most common in Bangladesh
M2b - most common in SE India
Haplogroup M3  - found mainly in South Asia, with highest concentrations in west and NW India
Haplogroup M4  - found mainly in South Asia but some sequences in Eastern Saudi Arabia
Haplogroup M4a - found in Gujarat, India
Haplogroup M30 - mainly in India, found in Middle East and North Africa.
Haplogroup M37a - found in Gujarat, India
Haplogroup M5  - found in South Asia
Haplogroup M5a - found in Orissa, India
Haplogroup M6  - found mainly in South Asia, with highest concentrations in mid-eastern India and Kashmir
Haplogroup M6b - found in Kerala, India
Haplogroup M7  - found in East Asia, especially in Japan
Haplogroup M8a:  - found in East Asia, especially in Japan
Haplogroup C  - found especially in Northeast Asia
Haplogroup C1  - found in Asia and America (Native Americans and Hispanics in particular)
Haplogroup Z  - found among diverse Eurasian populations: Hazara, Finns, Japanese, Sami and some Russians.
Haplogroup M9  - found in East and Southeast Asia
Haplogroup E - a subclade of M9 - found especially in SE Asia
Haplogroup M10  - small clade found in East Asia, Southeast Asia, Bangladesh, Central Asia, and southern Siberia
Haplogroup M11  - small clade found especially among the Chinese and some Bangladeshis
Haplogroup M12  - small clade found in Japan
Haplogroup G  - found especially in Japan with some isolated instances in diverse places of Asia
