CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -The more closely related two groups are, the more similarities they are likely to share. The series of evolutionary relationships among a group of organisms is termed phylogeny.

Detailed explanation-2: -A phylogeny, or evolutionary tree, represents the evolutionary relationships among a set of organisms or groups of organisms, called taxa (singular: taxon).

Detailed explanation-3: -A phylogenetic tree is a diagram that represents evolutionary relationships among organisms. Phylogenetic trees are hypotheses, not definitive facts. The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors.

Detailed explanation-4: -In scientific terms, the evolutionary history and relationship of an organism or group of organisms is called phylogeny. Phylogeny describes the relationships of an organism, such as from which organisms it is thought to have evolved, to which species it is most closely related, and so forth.

Detailed explanation-5: -Unless indicated otherwise, a phylogenetic tree only depicts the branching history of common ancestry. The pattern of branching (i.e., the topology) is what matters here. Branch lengths are irrelevant–they are simply drawn in whatever way makes the tree look most tidy.
