On a phylogenetic tree, ____ represents a common ancestor that existed before divergence.

In Oct 2022, a chilling discovery was made in Vuvatu, a country known for its extensive volcanic landscapes. Scientists found the remains of a large organism that had no resemblance to any current form of life on Earth. The organism also had no resemblance to any fossils ever found, including the very few fossils ever recovered from Vuvatu (fossils are rarely ever found in Vuvatu since volcanic landscapes are generally not conducive of fossilization). The world buzzed with the possibility that this was a crash site for an extraterrestrial body. An extensive study of the uncovered remains was conducted by many research facilities. Their conclusions regarding the organism’s features are listed below: Physical features: The organism has a surprisingly soft and malleable exoskeleton that reflects ambient light, creating mesmerizing patterns. In fact, the remains highly suggest that most of its body parts are soft and blubbery rather than rigid. Habitat: Given its relationship with…

Question: Species C, D, and F are species that live in the desert (desert-adapted mushrooms). Do you think "desert adaptations" are homologous or homoplasious? Explain your reasoning using the concept of parsimony. 0.2 Species_F Species_D Species_E Species_B Species_C Species_A

When several possible phylogenetic trees can be produced from a data set, the most parsimonious tree: O is the one that shows the smallest number of synapomorphies. O is the one that shows the largest number of nodes. O is the one that shows the largest number of analogous characteristics. O is the one that shows the smallest number of evolutionary changes. O is the one that shows the smallest number of branches.

Create a phylogenetic tree

On the right is a phylogeny depicting the relationship among eight animal species (A to H). Next to the species names are the tooth morphology of each species. For example, species A has prominent molar teeth, thus likely a herbivore. On the other hand, species C has prominent canine tooth, thus likely a carnivore. Which of the following statements is correct? O The most recent common ancestor for species A to H is probably a carnivore: O The most recent common ancestor for species A to H is probably a herbivore OIt is impossible to tell what the main food source is for the most recent common ancestor of species A to H. O For species C, D, E, F, G, there are four evolutionary events that lead to the evolution of canine tooth morphology If the common ancestor of species C, D, E, F, G is a carnivore, then the molar teeth for species D is a plesiomorphy.
