1 For less accessible burst pipes, such as underground or inside a wall, it can cost $400-$1,500 or more, depending on how much work it takes to uncover the burst pipe and if the work is done on an emergency basis. 2  A Denver plumber estimates fixing hundreds of burst pipes in one winter, with an average bill of $900. If the leak is under a concrete slab foundation, just repairing the pipe can cost $500-$3,800 or more; see How Much Does a Slab Leak Cost. 2  A spot repair can put additional pressure on the remaining pipes; it might be necessary to replace everything.
The team found that Native Americans most likely had a common Siberian origin, contradicting theories that an earlier migration from Europe occurred. The timeline Rasmus and his colleagues propose goes something like this: About 23,000 years ago, a single group splintered off from an East Asian population.
The first Native American group encountered by Columbus, the 250,000 Arawaks of Haiti, were enslaved. Only 500 survived by the year 1550, and the group was extinct before 1650. In the 15th century Spaniards and other Europeans brought horses to the Americas.uropeans also brought diseases against which the Native Americans had no immunity. Chicken pox and measles, though common and rarely fatal among Europeans, often proved fatal to Native Americans, and more dangerous diseases such as smallpox were especially deadly to Native American populations.
