Question

The major reason for extinction of Dinosaurs from the planet is _________.

• A. lack of food
• B. drastic changes in the environment
• C. lack of variations to support survival
• D. lack of conducive environment

Answer 1

The correct option is C

lack of variations to support survival

Dinosaurs became extinct when a huge meteorite hit planet earth; thousands of years back as per one of the scientific predictions. Sudden changes in the environment where they were living, made them totally inadaptable to fit themselves to the changes. Lack of survival adaptability can be attributed to the absence of suitable genetic variations in dinosaurs which otherwise could have given them a survival chance in adverse environments.
