Answer:
An analysis of 5,000-year-old genetic material from preserved human remains found in Sweden suggests that people moving from southern to northern Europe spread agriculture across that continent long ago.
In addition to agricultural know-how, the intrepid farmers brought their genes: They interbred with hunter-gatherer communities to create modern humans living in Europe today.
"Genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, though a number of hunter-gatherer genes remain," study researcher Anders Götherström, of Uppsala University in Sweden, said in a statement.
The results of this study, to be published in the April 27 issue of the journal Science, match up well with previous archeological evidence of farming in Europe.

Answer:
GIS is used Geographic Information System
Explanation:
GIS is used geographic information system. it used to analyze feature temporally and spatially. In spatially assessment, spatial distribution map which also defined as SDM Map are drawn to show variation between spatial feature. SDM are commanly used water quality assessment to assess quality of water between different region.
the main component of GIS is Mapping, monitoring, ,measuring management.
in environmental engineering GIS is used to locate the location of the data, which is used to draw variation between the region.
air quality modelling, water quality modelling are some attribute where GIS can work effectively
in computer engineering
GIS enables define digital maps, navigation instruments and instruments for spatial inclusion in computer science. It can also be used for web services
