To show evolutionary relationships based on traits
Each organism has a specific sequence of DNA, this is what makes up the organism itself appearance and functions. If a sequence in the DNA has changed, so has an aspect of the organism. If there are enough changes over time that a scientist has monitored, then a new or modified species has formed.
There are many ways in which scientists study the evolution of plants. Scientists may choose to study fossils in the area for example.

Charles Darwin contributed to the evolutionary theory through study of natural selection.
scientists can infer how closely related the organisms are in an evolutionary sense
The evidence do scientist use to determine evolutionary relationships by scientist have combined the evidence from DNA, protein structure, fossils, early development, and body structure to determine the evolutionary relationship amoung species.
To show evolutionary relationships based on traits
The tree you are referring to is called a phylogenetic tree. It is developed by scientists to show the evolutionary relationships between different animal phyla based on their shared characteristics and genetic information. These trees help to understand the evolutionary history and relatedness of different organisms.
Today, scientist rely primarily on information about the chemical makeup of cells to determine evolutionary history.
Scientists study the genetic material of organisms to determine their evolutionary history. By comparing DNA sequences between different species, researchers can identify similarities and differences that help reconstruct the relationships between species and their common ancestors.
Phylogenetic trees represent hypotheses about the evolutionary relationships among a group of organisms. A phylogenetic tree may be built using morphological (body shape), biochemical, behavioral, or molecular features of species or other groups.
What can lead scientists to change an evolutionary tree?
The theory of evolution was originally presented by Charles Darwin. Since the time of Darwin, there have been many other scientists who have contributed to evolutionary theory. One notable evolutionary scientist of the 21st century is Richard Dawkins.

A scientist who studies classification is called a taxonomist. Taxonomists are responsible for identifying, naming, and classifying organisms based on their evolutionary relationships and shared characteristics. Their work helps to organize and categorize the diversity of life on Earth.
