From: Making evolution stick: using sticky notes to teach the mechanisms of evolutionary change
Example of mechanisms during small group activity. This figure is intended to correspond with the worksheet in Additional file 1, using four colors of sticky note: orange, blue, pink, and green. a Initial population. b After founder effect from Boring Mainland (Ma) to Fun Island (Isl) + reproduction. c After gene flow + reproduction. d After genetic drift + reproduction. e After natural selection from predation of orange and blue notes + reproduction. f After bottleneck from alien bombs (impact sites determined by tossing balls of paper at the board) + reproduction. g Photos of activity implementation
