The correct answer iare A. All organisms have had one common ancestor in the past, and C. Gorillas share an extinct ancestor with bonobos.
Explanation
The image shows an evolutionary tree that resulted in species such as the chimpanzee, orangutan, gorilla, bonobo, and humans. This tree shows nodes, which are the points shown on it. These nodes represent an extinct species as a common ancestor of the species of the next node that are connected to it. Therefore, the correct answers are A. All organisms have a common ancestor in the past, this statement is true because all the species shown in the tree are the result of different divisions of a first species that lived 13 million years ago. The second correct statement is C. Gorillas share an extinct ancestor with bonobos. Because in the graph it can be seen that 6 million years ago there was a node/species that is the common ancestor of the gorilla and the bonobo.
