Which of the following is not part of the theory of evolution?

A.
Organisms tend to produce more offspring than can survive to reproductive age.

B.
Organisms can acquire changes during their lifetime that can help their species survive.

C.
Organisms that do not survive to reproduce do not pass on their traits.

D. Organisms have variations in traits within a population.

I'll be glad to check your answer.

The correct answer is B. Organisms can acquire changes during their lifetime that can help their species survive. This statement is not part of the theory of evolution. The theory of evolution is based on the concepts of variation, inheritance, and natural selection, which explain how species change over time. The idea that an organism can acquire changes during its lifetime and pass them on to its offspring is known as the theory of Lamarckian inheritance, which is not considered to be part of the modern understanding of evolution.

To determine which option is not part of the theory of evolution, we need to understand the theory of evolution itself.

The theory of evolution states that organisms change over time through a process called natural selection. This process leads to the adaptation and diversification of species over generations. Traits that are advantageous in a particular environment are more likely to be passed on to future generations, while traits that are disadvantageous are less likely to be passed on.

Now let's analyze each option:

A. Organisms tend to produce more offspring than can survive to reproductive age.
This option is indeed part of the theory of evolution. In every generation, organisms tend to produce more offspring than can survive, leading to competition for resources and survival of the fittest.

B. Organisms can acquire changes during their lifetime that can help their species survive.
This statement is not part of the theory of evolution. The theory of evolution is primarily concerned with changes in the genetic makeup of populations over time, not individual changes acquired during an organism's lifetime. The theory of evolution does not include the inheritance of acquired traits.

C. Organisms that do not survive to reproduce do not pass on their traits.
This statement is also part of the theory of evolution. Organisms that do not survive to reproduce do not pass on their genetic traits to future generations. Only the traits of organisms that successfully reproduce can be passed on to their offspring.

D. Organisms have variations in traits within a population.
This statement is indeed part of the theory of evolution. Variations in traits within a population are the raw material upon which natural selection acts. Some variations may be advantageous, allowing certain individuals to better survive and reproduce, leading to the spread of those traits in subsequent generations.

Based on the analysis above, the option that is not part of the theory of evolution is:

B. Organisms can acquire changes during their lifetime that can help their species survive.
