Yaks are wild and sometimes tame depending how/where they were bought up as young if they was bought up in the wild then they would be wild, if they were bought up in captivity or around humans/man kind then the will be tame but they cann always turn suddenly on you.
we should preserve them as they provide us (people living particularly in areas where yaks live)with milk,fur,fibre,meat,etc. which nowadays are basic needs of human beings
it doesn't have a specific name but is called as cotton wool
they are very well adapted to their own environment in the Himalayan regions, but cannot adapt to living in warmer climates
How many yaks are left in the world today?
about 12 million, mostly domesticated. Wild Yaks are classified as vunerable
Is yak a domestic or a wild animal?
Generally wild. They could be domestic, when reared as cattle for milk.
It you mean lacking in intelligence, then they are not dumb, they have intelligence according to their local needs.
If you mean refraining from any or much speech, then Yaks 'grunt'
Yaks tend to charge their foes either to gore them or trample them. If wounded, they will flee unless defending their young.
No. Yaks are found in Nepal, which is a country in East Asia, not Africa.
Yaks have a very thick fur coat that hangs down to their ankles.
What is the best way to preserve the yak?
Do just like with the American bison: treat them as a wild animal and yet raise them on a farm or ranch. Preserve them by only breeding yaks to yaks, never cross-breeding them.
And, create a movement to have a sanctuary or national park to keep these animals in the wild. They are also raised and used for beef and draft work in Nepal, so they are already being preserved there.
