What does not support the idea that galaxy interactions can shape their types?

The choice indicating that more distant galaxies have larger redshifts does not support the idea that galaxy interactions can shape their types because it primarily relates to the expansion of the universe and the relative motion of galaxies. Redshift is a phenomenon that occurs due to the Doppler effect, where light from objects moving away from us appears shifted toward the red end of the spectrum. This measure is used to understand the rate of expansion of the universe and the distance of galaxies, but it does not provide direct evidence of the interactions between galaxies themselves or how those interactions might influence their morphological characteristics.

In contrast, the presence of multiple galaxy clusters, variations in galaxy sizes and shapes, and the observation that closely located galaxies often exhibit disruptive features all serve as evidence for the influence of galaxy interactions. Galaxy clusters often contain various types of galaxies that might have interacted with each other, resulting in changes in structure or formation. Variations in sizes and shapes can emerge from gravitational interactions and mergers. Additionally, galaxies in close proximity frequently show signs of gravitational pull on one another, leading to distortions or disruptions indicative of interactions. Thus, these other choices underscore the mechanisms through which galactic interactions can affect galaxy morphology, while redshift is more related to cosmological observations.
