Concept explainers
To review:
An imaginary phylogenetic tree has to be created for an ancestral species along with ten descendants. A monophyletic group, a polyphyletic group, and a paraphyletic group have to be marked on the tree. The identified groups, which are marked on the tree must match the definitions of mentioned three groups.
Introduction:
The pictorial representation of an evolutionary relationship that exists among the living organisms is shown by a phylogenetic tree. The phylogenetic tree is based upon the similarities and differences in the genetic and morphological traits. The diversity of an organism can be easily studied using the phylogenetic tree as it indicates the relationship between the organisms.

- Identify the correct statement regarding the phylogenetic tree using the illustration provided below?arrow_forwardExamine the following phylogenetic tree illustrated in Figure shown in the first picture. In general, what does a phylogenetic tree illustrate? How do you compare the relationships of organisms BB, CC, and DD? Given the following organisms in the Table in the second picture, number them in terms of which is relatively closest and distant. Number 1 refers to closest.arrow_forwardCircle and label the latest common ancestor between taxon A and E in your tree above.arrow_forward
- create a cladogram summarizing the phylogenetic relationships among the different Phyla. Take note that some characters may be secondarily lost during the evolution of these different. there is a photo of example of cladogram belowarrow_forwardWhat is the purpose of using an “outgroup” when reconstructing a phylogenetic tree?
