Question

What is meant by Phylogenetic Relationships......?? Describe in detail....​

Answer 1

Answer:

Phylogenetic trees come about through successive events of speciation (branching), in which one species gives rise to two.

“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors.

Answer 2

Required Answer ✋

• Phylogenetic Relationships

A phylogenetic Relationship or Evolutionary Tree is a branching diagram or "tree" showing the evolutionary relationships among various biological species or other entities—their phylogeny —based upon similarities and differences in their physical or genetic characteristics.

• Simplified Definition

“Phylogenetic relationship” refers to the relative times in the past that species shared common ancestors.

• Basis of Phylogentic Classification

Phylogenetic classification system is based on the evolutionary ancestry.

It generates trees called cladograms, which are groups of organisms that include an ancestor species and its descendants.

Classifying organisms on the basis of descent from a common ancestor is called phylogenetic classification.

• Importance of Phylogeny

Phylogenetics is Important because it enriches our understanding of how Genes, Genomes, Species (and molecular sequences more generally) Evolve.

• Advantages of Phylogeny

Phylogenetic classification has two main advantages over the Linnaean system.

First, Phylogenetic Classification tells you something important about the organism: its evolutionary history.

Second, phylogenetic classification does not attempt to "Rank" organisms.

• History of Phylogentic Classification

Linnaeus classified organisms based on obvious physical traits. Basically, organisms were grouped together if they looked alike.

After Darwin published his theory of evolution in the 1800s, scientists looked for a way to classify organisms that showed phylogeny.
