DARWIN’S THEORY OF NATURAL SELECTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How does natural selection lead to evolution?
A
The stronger offspring kills the weaker members
B
Stronger traits are passed on to the next generation of the species
C
Overproduction provides energy to enhance the stronger species
D
environmental changes kill weaker members of the species
Explanation: 

Detailed explanation-1: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-2: -As conditions change, natural selection favors one allele or genetic variant over another. Genes that can facilitate a range of different forms under different environments (phenotypic plasticity) can also help an organism adapt to changing conditions.

Detailed explanation-3: -Through natural selection, certain traits that are beneficial are more likely to be passed on to future generations while detrimental traits may be less likely to survive. Over time, this process of natural selection can lead to an increase or decrease in genetic variation due to selective pressures on certain traits.

Detailed explanation-4: -Natural selection requires variation between individuals. Mutations and sexual reproduction increase genetic variation in a population. Natural selection occurs when environmental pressures favor certain traits that are passed on to offspring. The “big prize” in natural selection is passing on genetic information.
