The most important feature used to classify animals is Body structure!
An observable characteristic of an organism is a trait or feature that can be easily seen or measured, such as its color, size, shape, or behavior. These characteristics are often used to identify or classify different species within a group.
Scientists primarily use genetic material (DNA) as the main feature for classification. By analyzing DNA sequences, scientists can determine the evolutionary relationships between different organisms and group them accordingly. This approach, known as molecular phylogenetics, has revolutionized the way we understand and classify life on Earth.

An adaptive feature is a characteristic or attribute of an organism that has evolved over time to better suit the organism's environment or increase its chances of survival and reproduction. These features are a result of natural selection acting on the genetic variability within a population.
