Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
Organisms that are closely related to rabbits include; horses and turtles
A group of closely related organisms that cannot mate are considered different species. Species are defined as groups of organisms that can interbreed and produce fertile offspring with one another. When individuals from different groups are unable to produce viable offspring due to genetic differences, they are considered separate species.
Branching tree diagrams (or cladograms) attempt to show the ancestral relationships between species. The groupings indicate relatedness - closely grouped organisms will be more closely related (sharing a more recent common ancestor) than organisms which descend from earlier divisions, which will be further away on the cladogram.
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.

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.

Family and kingdom
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.
