Question

Are these statements true or false

1. Evolution serves a purpose, strives for perfection, or occurs “in order to help a species survive.”

2. Populations and species can evolve over time, but individuals cannot evolve.

3.Two populations are separated, but individuals migrate back and forth about twice a year. In this case speciation will never occur.

Answer 1

1. The statement is false . Because evolution does not have any purpose for any species . It is the natural process by which the advantageous genes are suited in the respective environment and others not.

2. Populations and species can evolve over time, but individuals cannot evolve. The statement is true . This is an example of natural selection, individuals retains the same gene throughout their lifespan.

3. The statement is true. When populations are seperated, migrated and becomes dividend which cannot interbreed .Then seperate population can begin to develop new traits which steps to speciation.
