´╗┐Ishaan Khanna Candidate Number: 0026011 ESS Practical Planning Research Question: How does biodiversity favour survival through natural selection? Natural Selection: The process in nature by which, according to Darwin's theory of evolution, only the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.[1] Biodiversity: The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. ...read more.

One other weakness of the experiment is that: had I taken dark coloured crayons instead of the light ones in the first case then I may not have got the same survival rate. Conclusion: When the diversity is high the rate of survival is high and when the diversity is low the rate of survival is also low. This proves that nature DOES find a way to maintain biodiversity. ...read more.
