Answer:
A scientist made the claim that genetic inheritance of a mutated gene is more beneficial to an organism over time and contributes to biological fitness. They would make this claim because over time genes change to adapt to their surroundings and this is called evolution. Overtime environments change and the organisms living in them have to adapt or they will more than likely die. A mutated gene can contribute to biological fitness by giving the organism certain characteristics that could help it survive longer. Also, organisms with higher fitness pass more copies of their genes to the next generation which prevent the organisms from going extinct all together. In conclusion, a scientist would make this claim because over time genes need to mutate in order to survive in a changing environment.
