White skin developed in Europe only as recently as 8,000 years ago ~ Based on 83 human samples from Holocene Europe as analyzed under the 1000 Genomes Project, we now know that for the majority of the time that humans have lived in Europe, the people had dark skin, and the genes signifying light skin only appear within the past 8,000 years. This recent and relatively quick process of natural selection suggests that the traits which spread rapidly were advantageous within that environment.
First off, this is NOT a typical PowerPoint that simply lists main idea bullets. This is an interactive tutorial using engaging pictures, animations, and questions that require student input in order to proceed. This tutorial will guide students through the process of evolution by natural selection.
This is a free 20 page homework or classwork bundle includes short answers, fill in the blanks, complete diagrams, crossword puzzles, and much more. Topics addressed are Evolution, Mechanisms of Natural Selection, Life Origins, Human Evolution, Earth System History, and Ecological Succession. -Enjoy! Science from Murf LLC
I LOVE THIS. Kids take two different animals and combine their adaptations to create a whole new animal, labeling each part of course. Where does the new animal live? What does it eat? Is it a predator?
