Importance of Evolution:
i) Evolution is the only scientific explanation for the diversity of life. It explains the striking similarities among vastly different forms of life, the changes that occur within populations, and the development of new life forms.
ii) Evolution helps us to classify the vast diversity of organisms.
ii) The principles of evolution underlie improvements in crops, livestock, and farming methods. Example - Natural selection accounts for the rise in pesticide resistance among agricultural pests and informs the design of new technologies to protect crops from insects and disease.
iii) Scientists are applying lessons from evolutionary biology to environmental conservation. Example - Plants and bacteria adapted to polluted environments are being used to replenish lost vegetation and to clean up toxic environments.
iv) Understanding evolution is also central to the advancement of medicine. Concepts such as adaptation and mutation inform therapies and strategies to combat pathogens, including influenza. Scientists are using the principles of natural selection to identify new drugs for detecting and treating diseases such as cancer.
