Question

Quizplus · Accepted Answer

The most logical explanation for two different species having similar features (or traits) is that they inherited these traits from a common ancestor. This is the basis of the theory of evolution, which suggests that species change over time through the process of natural selection. Over generations, genetic mutations occur that can lead to new traits and adaptations, but some traits may be conserved because they provide a survival advantage. Therefore, similar traits in different species can be seen as evidence of common ancestry. Genetic drift, gene flow, and artificial selection can also affect the gene pool of a population and ultimately lead to differences among species, but is less likely to result in similar traits between two different species.
