Correct option is B
Explanation:
To determine the correct phylogenetic relationship among apes, we need to consider evolutionary lineage based on genetic and morphological evidence. The correct evolutionary tree should follow the established Great Ape phylogeny:
- Humans and chimpanzees share the most recent common ancestor.
- Gorillas are the next closest relatives.
- Orangutans diverged earlier than gorillas, chimpanzees, and humans.
- Gibbons are the most distantly related, forming an outgroup to all great apes.
Thus, the correct hierarchical relationship is:
(((Humans,Chimpanzees),Gorillas),Orangutan),Gibbons
This matches Option 2, making it the correct answer.
Information Booster:
- Gibbons (Family: Hylobatidae): The most distantly related to great apes, forming an outgroup.
- Orangutans (Genus: Pongo): The first to diverge from the lineage leading to gorillas, chimps, and humans.
- Gorillas (Genus: Gorilla): Share a common ancestor with humans and chimpanzees but diverged earlier than them.
- Chimpanzees & Humans (Genus: Pan & Homo): The closest relatives, sharing about 98-99% of their DNA.
