Compound interest. Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously-accumulated interest.
Guanches (also: Guanchis or Guanchetos) refer to the aboriginal Berber inhabitants of the Canary Islands. It is believed that they migrated to the archipelago around 1000 BC or perhaps earlier.

Professor Anders GÃ¶therstrÃ¶m, co-author and director of the ancient DNA laboratory at Stockholm University, explains these findings: Our analyses show that a small portion of the genetic ancestry of the Guanches was derived from populations most closely related to European Stone Age farmers.
