Science stories

Beothuk DNA in Newfoundland suggests they are related to the Mikmac.

Wikipedia has the story of their slow extinction, including outright murder and deliberate capture of women (including one captive that might have gone home with the Vikings).  But most of them died from the usual reasons: disease and displacement by aggressive newcomers.

the article includes stories of some of the survivors past that point but mainly those who intermarried outside the tribe.

"The Beothuk were unable to procure sufficient subsistence within the areas left to them."[5] They entered into a cycle of violence with some of the newcomers.
Beothuk numbers dwindled rapidly due to a combination of factors, including: loss of access to important food sources, from competition with Inuit and Mi'kmaqs as well as European settlers; infectious diseases to which they had no immunity, such as smallpox, introduced by European contact; endemic tuberculosis (TB), which weakened tribal members...
By 1829, with the death of Shanawdithit, the people were officially declared extinct.[8] 

 Sigh.

The story of many indigenous folks.

nor is it the first one to do so:

n 1979, NASA’s Skylab space station hit Australia during its own fall to Earth, and the Soviet Union’s Salyut 7 space station followed suit over Argentina in 1991.
