LIFE SCIENCE

Detailed explanation-1: -Individual organisms don’t evolve. Populations evolve. Because individuals in a population vary, some in the population are better able to survive and reproduce given a particular set of environmental conditions.

Detailed explanation-2: -But evolution produces a tree, not a ladder-and we are just one of many twigs on the tree. MISCONCEPTION: Individual organisms can evolve during a single lifespan. CORRECTION: Evolutionary change is based on changes in the genetic makeup of populations over time. Populations, not individual organisms, evolve.

Detailed explanation-3: -All organisms, including humans, evolve over time. Evolution occurs through natural selection, and is a force that has shaped every organism living today.

Detailed explanation-4: -Answer and Explanation: True. Individuals do have the ability to adapt to their environment if they are provided with enough time, and possess some type of mechanism, usually sexual reproduction, which is able to generate variation.

Detailed explanation-5: -The given statement is true. Evolution is a very gradual process that spans millions of years and has given rise to complex or highly organised organisms from simple ancestors.
