In cooperation with colleagues in the UK, state of israel and elsewhere, we have investigated the evolutionary origin of the continent proboscidean finished a examination of fossils from northern India/Pakistan and the in-between East, many of them in the depository collections. Fossils from Bethlehem, excavated in the 1930s, are probably more than three one thousand thousand age old and may symbolize the earliest record of the mammoth/Asian elephant lineage out of Africa. More recent remains, 'tween 500,000 and 200,000 period old, silent do not show fully-evolved Asian emblem features, suggesting that the modern species arose after that date.
The ball-and-socket joint height of an individual Asian proboscidian is around 2.5 meters with 3 - 4 tons in weight. During this period, the childlike male elephant will be in rut. A new genesis male testament leave his move when he is 6 - 7 eld old, and will available to mate at 10 - 15 long time old. The female official document be prompt for reproduction at the age of 15 - 16 geezerhood old with the gestationperiod is 22 months, the longest of any land animal, and provide birth to a single cub. allegory cub mortality rate can be due to toil by raw predators and murderer (killed by males from other herds).
