Two ways: 1) they can compare DNA sequences to see how far they've diverged; and 2) they can study the fossil record to look for physical similarities and differences.
The study of all living things-plants and animals is Biology

Biogeography is the study of these patterns in the distribution of plants and animals around the world, considering factors such as climate, geography, and evolution.
Botany is the scientific study of plants, including their structure, growth, classification, and interactions with the environment. Botanists also investigate plant evolution, diversity, and the ways in which plants are utilized for food, medicine, and other purposes.
Botanists study a wide variety of plants, ranging from mosses and ferns to trees and flowers. They may focus on specific groups of plants, such as orchids or grasses, or study plant ecology, physiology, genetics, or evolution. Botanists play a crucial role in understanding plant diversity, function, and conservation.
The branch of science that includes the study of plants, animals, and the human body is biology. Biology focuses on the study of living organisms, their structure, function, growth, origin, evolution, and distribution.

there are many sceintist that are involved in this like robert koch for malaria and ronald ross on tuberculosis.
Biologists, paleontologists, geneticists, and anthropologists are some of the scientists who study evolution. They analyze fossils, genetic data, and comparative anatomy to understand how species evolved over time. The theory of evolution was proposed by Charles Darwin in the 19th century, and his ideas laid the foundation for the study of evolution.
Studying plants is called botany. It encompasses the scientific study of all aspects of plant life, including their structure, growth, reproduction, evolution, and interactions with the environment.
