Answer 1

Answer: (B)

Evolution

• The adjustment or changes in behaviour, physiology, and structure of an organism to become more suited to an environment is called evolution.
• Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another.
  
• According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
