Question

What is a phylogenetic diagram?

Answer 1

Evolution is the process by which organisms are able to change their genes to adapt to the environment around them. The evolution of organisms is the reason why there is so much biodiversity on the planet today.

Complete answer:
Evolution is the reason for biodiversity today. Evidence shows that all of the lifeforms on earth originated from one single-celled organism. Therefore all organisms have been created from other organisms. Thus this is why there are many traits and genes that connect different organisms. For example, all mammals have mammary glands.
A phylogenetic tree is a tree that maps out the genetic relationships and connections that are present between organisms from different groups. These trees are able to shed light on the evolutionary nature of a group. They can help to show the way in which two different groups are connected. So if we were to map a phylogenetic tree that shows the connections of primates to other mammals, then we can show that all mammals have mammary glands however primates have hands with opposable thumbs on them.
These groups help researchers to tell which groups are close relatives to each other and which groups are further away. This information can be used to connect organisms.

Note:
A phylogenetic diagram can be used to map the evolutionary relationship between organisms that come from different groups. These trees are extremely useful for studying how animals have evolved over time.
