Complete question:
(b) Using the template of the phylogenetic tree, circle the lineages that share node A. You will find the tree in the attached files.
Answer:
The Lineages that share node A are
- Chinese river dolphin
- Amazon river dolphin
- La Plata river dolphin
- Dolphins
- Narwhal
- Porpoises
Explanation:
The phylogenetic tree is composed of,
- Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
- Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
- Root → This is the older common ancestor that all lineages share. The first one in the tree.
- Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
- Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
- Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
- Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
- Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.
Firstly the question is incomplete the image is not attached with it which shows the phylogenetic tree.
The Lineages that percentage node A are
- Chinese river dolphin
- river dolphin
- La Plata river dolphin
- Dolphins
- Narwhal
- Porpoises
The phylogenetic tree consists of:
- Lineages → These are the taxonomic companies of hobby located withinside the extremes of the traces referred to as branches.
- Nodes → These are the ramification points, that are additionally called divergence points. They constitute the area of the maximum latest not unusual place ancestor.
- Root → This is the older not unusual place ancestor that every one lineages percentage. The first one withinside the tree.- Two or extra
- lineages are extra associated with every difference in the event that the percentage a latest not unusual place ancestor. In this manner, all of them diverge from the equal node.
Two or extra lineages are much less associated with every difference in the event that they lack a latest not unusual place, ancestor. This is, the node from which those lineages diverge is located a long way away withinside the tree.
There also are one-of-a-kind phylogenetic relationships among lineages.
• Apomorphies → Occur while the worried lineages percentage a trait that they inherited from their maximum latest not unusual place ancestor. This trait developed for the primary time on this ancestor. → This dating is a homology.
• Plesiomorphies o( while the worried lineages percentage a trait inherited from a not unusual place ancestor, however, this is older regarding the prevailing developments exhibited via way of means of different descendants of the equal not unusual place ancestor. This dating is a homology.
• Homoplasy → Lineages percentage is a trait that developed independently in every group. → This dating is an analogy.
What is the phylogenetic tree?
The phylogenetic tree is the branching diagram showing the evolutionary relationships among various biological species.
