Question

Dryopithecus is more similar to
(1) Ape
(2) Gorilla
(3) Chimpanzee
(4) Man

Answer 1

Hint: A fossil anthropoid ape from the middle Miocene to the early Pliocene periods, belonging to a genus that includes the presumed common ancestor of gorillas, chimps, and humans.

Complete answer:
Features of Dryopithecus
1. Time span: 23 million to 8 million years ago.
2. Arboreal habitat includes both rain forests and open fields.
3. Sizes range from gibbons to gorillas.
4. Diastema, large teeth, interlocking canines
5. Cusp Y-5 Pattern.
6. Limbs- a combination of ape and monkey traits.
7. An indication of the ape-simian shelf.
Walker and Tifford measured its cranial capability to be about 167 cubic centimetres. According to this, the brain size of africanus was greater than that of monkeys in comparison to body size.
The existence of a frontal sinus suggests that he was linked to humans and African apes.
Early Dryopithecus fossils (first definite finding in 1856) were mostly teeth. We now have a cranium as well as several log bones. This has not only expanded our subject awareness of Dryopithecus, but it has also helped to scientifically validate previous conclusions.

Dryopithecus is thought to be the ancestor of both humans and modern apes.

Note:
Dryopithecus postcranial fossils discovered in the last decade indicate that his limbs share certain features with modern apes and monkeys. Based on the analysis of these sections, it is inferred that africanus was a slow-moving animal that lived in trees, and that his limbs were not adapted for brachiation or climbing.
