15 EVOLUTIONARY GEMS : Classic examples of Evolution
Year 2009 holds a special place in the field of Evolution as it celebrates 200 years of Charles Darwin’s Birth(12 February 2009) and 150 years of Publication of one of the greatest books “Origin of species”(24 November 2009).To celebrate these events and to create more awareness among the general public by providing evidence for evolution by natural selection,the editors of Nature(Henry Gee, Rory Howlett and Philip Campbell) came out with a compilation of some great examples of evolution.These enlightening examples were part of Nature’s issue during the last decade,which displays breadth, depth and power of evolutionary thinking and will definitely help teachers to spread the current knowledge favouring evolution by natural selection.Given the situation of schools in United states and many parts of world this effort by the editors will be most welcome,especially for for those people who are who aren’t sure about evolution -which is a majority (around 55%) according to some surveys.
The examples are divided into three parts depending on data available on Fossils, habitat and molecular process.Fossils offer exceptional evidence for evolution in action,giving us the minute details of creatures which became extinct long back.
