Learn about phylogenetic trees and their role in understanding evolutionary relationships on Khan Academy.
Learn about the logic behind phylogenetic trees and how to build a tree using data about features that are present or absent in a group of organisms.
Solving problems with phylogenetic trees. Conservation genetics and conserving biodiversity. Genes and health—moving beyond race. Malaria—natural selection and new medicine. Our balancing act with viruses. What is a virus? Quiz: Evolution and human health.
In this article, we'll take a look at phylogenetic trees, diagrams that represent evolutionary relationships among organisms. We'll see exactly what we can (and can't!) infer from a phylogenetic tree, as well as what it means for organisms to be more or less related in the context of these trees.
A phylogenetic tree, also known as a cladogram, is a diagram that proposes how different types of living things are related. If you follow the lines connecting any two groups on a tree, you'll get an idea of how closely related they are.
A phylogenetic tree of living things, based on RNA data and proposed by Carl Woese, showing the separation of bacteria, archaea, and eukaryotes. It is from wiki. I think the difference is the ability to live in the different conditions and the complexity which was allows by those conditions.
Constructing a phylogenetic tree involves hypothesizing evolutionary relationships among species based on observable traits and genetic evidence. By practicing parsimony, we aim for the simplest explanation.
Learn about phylogenetic trees and how to interpret them to determine which species are most related.
