Question
n Flores Man is from a new fossil recently discovered in Indonesia. Flores Man ukely split from the lineage leading to us about 2 million years ago. Where would Flores Man be placed on the following cladogram of the great apes? They should go in position: a.A b.? ?.? d, D e, NONE ofthe above Chimp (Pan troglodytes) Bonobo (Pan paniscus) 2 Human (Homo sapiens) Gorilla (Gorilla gorilla) Orangutan (Pongo pygmaeus) 21. Which of the labeled ancestral nodes is the oldest? (Which is furthest in the past?) b. node 2 c node 3 d. node 4 a. node 1 e. CAN'T TELL (cladograms do not show which extant species is the oldest). 22. What can be said about the way orangutans are depicted in this cladogram. a. Nothing - cladograms do not have information about the evolutionary history of extant species b. Orangs are the oldest species of great ape. c. Orangutans have more primitive characteristics than great apes. d. Orangs are shown as with fewer extant close relatives than the other great apes. e. Orangutans speciated from the human lineage after the two split from the chimps. 23. Ancestral noderepresents the speciation event where the lineages leading to chimps and humans split from each other. d. node 4 e. NONE of the above c. node 3 b. node 2 a. node 1Explanation / Answer
20.
d. D
Reason: D is the only branch that splits form human lineage.
21.
a. node 1
Reason: In the above diagram leftmost node is oldest and we come in more recent times as we go right.
22.
b. Orangs are oldest species of great apes.
Reason: Using the same logic as in question 21, since orangs split earliest, they are the oldest species among the great apes.
23.
c. node 3
Reason: At node 3 human lineage separates from chimps and bonobos.
