Question

Choose the correct answers from the alternatives given .
Evolution

• A. Is the process by which the Earths diversity of life came about
• B. Can be studied at the cellular level
• C. Can be studied by ecologists
• D. All of the above

Answer 1

The correct option is D All of the above

Evolution is a change in the genetic makeup (and often, the heritable features) of a population over time. It can be studied at a cellular level to observe evolutionary similarly among organisms. Evolution is also resultant of the interaction of organisms to their environment, hence it can be studied by ecologists. Biologists sometimes define two types of evolution based on scale:

• Macroevolution, which refers to large-scale changes that occur over extended time periods, such as the formation of new species and their diversification.
  
• Microevolution, which refers to small-scale changes that affect just one or a few genes and happen in populations over shorter timescales.
  

So, the correct option is 'All of the above'.
