Concept explainers
To explain: The way in which an individual would decide whether the new discovered organism is an animal.
Concept introduction: Animal phylogeny is the rapidly changing field for the biologists. Even if the members of animal kingdom are incredibly diverse, there are various animals sharing certain features that differentiate them from other organisms of the kingdom.
To explain: The characters that might be contribute to the decision of the individual to decide the newly discovered organism as an animal.
