A simplified example of mating behavior.
If young men wanted old women as mates their genes would be selected out, as they would have few children to pass those genes to, until negative frequency selection reduced these allele in the gene pool. Men who desire young, fertile women as mates leave many descendents that carry the genes for this trait. So, over generations the mating behavior of men is shaped. and stabilizing selection keeps this mating trait/allele at high frequency in the populations gene pool.

Darwin was the first scientist to have the courage to put forward the theory of natural selection.
Well this could be an advantage to the insects because the insects can conceal with the color of the sticks. This trait could have evolved the through natural selection because its a chance of staying alive.
Darwin called his theory "natural selection" or "survival of the fittest." It explains how species evolve and adapt to their environment over time through the process of natural selection.

One of the conditions of natural selection is that variant organisms are selected on their superior adaption to the environment, reproductive success and their passing on of these traits to progeny, as populations evolve. A genetic component is the physical molecule that is inherited by progeny which reflects their parents successful trait. This is the '' hard '' inheritable component of behavior.
Yes, penguins, like all animals, have gone through natural selection. Scientific evidence supports this notion.
Yes, the theory of evolution by natural selection is an example of a falsifiable theory. This means that it can be tested and potentially proven wrong through empirical evidence.
Through natural selection and evolution
No, our ability to drive automobiles is not a trait that has evolved through natural selection. Driving is a learned skill and is not influenced by genetic traits that are subject to natural selection.
Inherited behavior refers to behaviors that are passed down from one generation to the next through genetics. These behaviors are instinctual and are not learned during an individual's lifetime. Inherited behaviors are influenced by genes and are typically present in a species as a result of natural selection.
Charles Darwin is known for the theory of evolution through natural selection. He proposed that all species of life have descended over time from common ancestors, and that the process of natural selection is the mechanism through which this evolution occurs.
