Question

Which of the following is not associated with the Darwin's natural selection?

• A. Parents pass their successful traits onto their offsprings.
• B. Population members exhibit variations in many traits.
• C. All living organisms use the same genetic code.
• D. Environmental pressures can select various traits based on survivability.
• E. Populations that adapt to environmental conditions produce many offsprings.

Answer 1

The correct option is C All living organisms use the same genetic code.

According to Darwin's Theory of Evolution by Natural Selection, more individuals are produced each generation that can survive. Phenotypic variation exists among individuals and the variation is heritable. Those individuals with heritable traits better suited to the environment will survive

Darwin’s process of natural selection has four components.

Variation. Organisms (within populations) exhibit individual variation in appearance and behavior. These variations may involve body size, hair color, facial markings, voice properties, or number of offspring. On the other hand, some traits show little to no variation among individuals, for example, number of eyes in vertebrates.

Inheritance. Some traits are consistently passed on from parent to offspring. Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.

High rate of population growth. Most populations have more offspring each year than local resources can support leading to a struggle for resources. Each generation experiences substantial mortality.

Differential survival and reproduction. Individuals possessing traits well suited for the struggle for local resources will contribute more offspring to the next generation.
