You can tell how closely related organisms are by determining the lowest classification that they share. For example, organisms that share the same genus will be more closely related than organisms that share the same family.
Scientists can tell whether organisms are closely related by comparing their DNA. This will allow then to look at various traits and features so as to compare the relationship between organisms.
Taxonomy and evolution are related because the system of taxonomy is based on evolutionary and genetic differences.

The plant most closely related to the ginkgo is the conifers.
I would say that Behavioral Science and Neuroscience are most closely related to Psychology.
Organisms that are in the same genus, which is the level just above species in the taxonomy chart, are most closely related. They share more recent common ancestors compared to organisms in the same family, order, or class.
Affinis is a Latin term that means "related" or "connected." It is often used in biological taxonomy to indicate organisms that are closely related or belong to the same genus.
When using genus and species in taxonomy , the genus will be the same for two very closely related organisms. The species will separate them.
Organisms that are closely related to rabbits include; horses and turtles
Closely related: obelia jellyfish Not closely related (but still related): coral sea anemone

Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
The science of classifying organisms is called taxonomy. Taxonomy involves the identification, naming, and organizing of living organisms into various categories based on their characteristics and evolutionary relationships. The process of taxonomy helps scientists understand the diversity of life on Earth and how different organisms are related to one another.
Humans and chimpanzees are closely related organisms, sharing a common ancestor. Additionally, dogs and wolves are closely related, with domestic dogs descending from wolves through selective breeding.
The lusus is, in absolute, the lowest.The lowest categories are:* lusus for botany* forma (or morph) for zoology* strain for mycology* biovar for bacteriology* serovar for virology In official taxonomy, the lowest recognized categories are the form (for botany) and the subspecies (for zoology).
