    Australia not found accidentally, study suggests

    Australia's colonization may have been an organized affair rather than an accident, a new analysis suggests.Some 50,000 years ago, aboriginal human settlers arrived on the continent, but how many people it took to found Australia's population is unknown. The new study, published Tuesday (April 23) in the journal Proceedings of the Royal Society B, suggests that about 1,000 to 3,000 individuals originally landed on Australia's shores.
