Recency of common ancestry. Species A is more closely related to species B than to species C if (and only if) the last common ancestor of A and B lived more recently than the last common ancestor of A and C. The concept can be applied not just to species but also to organism, populations, or genes.

Why do phylogenetic trees provide strong evidence of evolution?
With the nested hierarchy of phylogenetic trees in front of you, showing in general relief the biochemical, physiological, behavioral relatedness extended from the forked nodes, and going along through time one sees evolution in action. Change over time.
What is the usefulness for phylogenetic trees?
The phylogenetic tree is used for the study of evolutionary Biology. The phylogenetic tree is a symbolic diagram that is meant to represent the similarity and differences of different species for comparison with common evolutionary relatives.
The sense of relatedness to a central tone is known?
tonality
Which of kingdoms is at the bottom of phylogenetic tree?
Archaebacteria
What is phylogenetic constraint?
Phylogenetic Constraint is like a basic body plan. It can be modified (what evolution does) but it can't be fully changed. Vestigial features (things like the human appendix which is a remnant of our ancestors, but is no longer used) provide evidence of common ancestry and phylogenetic constraint. :)
Discuss the phylogenetic tree of life How the tree shows the relatedness of organisms?
Bacteria, Archaea, Eucarya
In addition to the morphological cultural and physiological tests performed on an unknown what can be conducted to further assist in its identification?
The classification of higher organisms utilizes PHYLOGENETIC approaches to determine relatedness or phylogeny.

Why is phylogenetic classification more natural than a system based on characteristics such as medical uses fullness or the shapes sizes and colors of the body structures?
Because it most truly reflects this relatedness because it is based on evolutionary data

What is slow evolution?
Slow evolution refers to a gradual process of change in species over long periods of time through natural selection and genetic variation. It often involves small, incremental changes in traits that accumulate over generations, leading to the diversification of species and the development of different characteristics. This slow pace of evolution contrasts with rapid evolutionary changes that can occur in response to sudden environmental shifts or selective pressures.
What is relatedness needs?
Relatedness needs for children is a sense of significant connection to others; the need for close personal relationships and the sense of one's self as worthy of love
The sense of relatedness to a central tone is known as?
tonality
