CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Phylogenies based on molecular characters assume that the more similar the sequences are in two organisms, the more closely related they are. Different genes change evolutionarily at different rates and this affects the level at which they are useful at identifying relationships.

Detailed explanation-2: -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-3: -The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.

Detailed explanation-4: -The Relationship Between Taxonomy and Phylogeny It is commonly understood that taxonomy should reflect phylogeny-organisms should be grouped according to their evolutionary history, their relatedness.

Detailed explanation-5: -Similar traits can be either homologous or analogous. Homologous traits share an evolutionary path that led to the development of that trait, and analogous traits do not. Scientists must determine which type of similarity a feature exhibits to decipher the phylogeny of the organisms being studied.
