The contact between the thumb and the tip of the little finger of the same hand is the...
Correct Answer
A. Ulnar opposition
Explanation
Ulnar opposition refers to the movement of the thumb towards the little finger, allowing the tips of both to touch. This movement is unique to humans and some primates, and it enables a precise grip and manipulation of objects. The contact between the thumb and the tip of the little finger of the same hand is a clear example of ulnar opposition, as it involves the specific movement and positioning of these two digits.
2.
Which of these is a characteristic of human evolution?
Correct Answer
C. Descended larynx
Explanation
A descended larynx is a characteristic of human evolution. The larynx, or voice box, is positioned lower in the throat in humans compared to other primates. This anatomical change allows for the development of complex speech and language abilities. The descended larynx creates a longer vocal tract, which enables humans to produce a wide range of sounds and articulate words more effectively. This adaptation is believed to have played a crucial role in the evolution of human communication and social interactions.
3.
Which of these is one of the oldest known primate-like mammal species?
Correct Answer
B. Plesiadapis
Explanation
Plesiadapis is one of the oldest known primate-like mammal species. It lived during the Paleocene epoch, around 65 to 55 million years ago. Plesiadapis had primate-like characteristics such as forward-facing eyes, grasping hands and feet, and teeth similar to those of early primates. Its fossil remains have been found in North America and Europe, making it an important species for understanding the evolution of primates.
4.
The Archicebus species came from...
Correct Answer
A. China
Explanation
The correct answer is China because the Archicebus species is believed to have originated in China based on fossil evidence. Fossils of Archicebus have been found in the Hubei Province of China, indicating that this species lived in that region during the Eocene epoch, approximately 55 million years ago. These fossils provide important insights into the early evolution of primates and suggest that China played a significant role in the diversification of primates during this time period.
5.
The earliest known catarrhine is...
Correct Answer
C. Kamoyapithecus
Explanation
Kamoyapithecus is the correct answer because it is the earliest known catarrhine. Catarrhines are a group of primates that includes Old World monkeys, apes, and humans. Kamoyapithecus is believed to have lived about 25 million years ago and is considered an important ancestor of the modern catarrhines. Wiilokitheca, Arapinidae, and Lomopitheucis are not known as early catarrhines and do not have the same significance in evolutionary history.
6.
The earliest Old World monkey is the...
Correct Answer
A. Victoriapithecus
Explanation
Victoriapithecus is considered the earliest Old World monkey because it is one of the oldest known fossil primates from Africa. Fossils of Victoriapithecus have been found in Kenya and Uganda, dating back to around 15-20 million years ago. These fossils provide important evidence for the evolution of monkeys and their presence in Africa during the Miocene period. The discovery of Victoriapithecus helps scientists understand the early diversification and adaptation of Old World monkeys in Africa.
7.
Which of these is a species of the Australopithecus genus?
Correct Answer
B. Sediba
Explanation
Australopithecus is a genus of early hominins that lived in Africa between about 4 and 2 million years ago. One of the recognized species within this genus is Australopithecus sediba. Discovered in South Africa, A. sediba is known for its mix of primitive and more modern traits, providing significant insight into the evolution of early human ancestors.
8.
A species of the Kenyanthropus include...
Correct Answer
C. Platyops
Explanation
Platyops is the correct answer because it is a valid species of Kenyanthropus. Kenyanthropus platyops is an extinct hominin species that lived approximately 3.5 million years ago in Kenya. It is known for its flat face and small teeth, which differentiate it from other hominin species. The discovery of Kenyanthropus platyops has provided valuable insights into the diversity and evolution of early hominins.
9.
A species of Paranthropus genus is...
Correct Answer
B. Boisei
Explanation
Boisei is the correct answer because it is a recognized species within the Paranthropus genus. Paranthropus boisei, also known as "Nutcracker Man," is an extinct hominin species that lived in East Africa around 2.3 to 1.2 million years ago. It is characterized by its robust cranial and dental features, indicating a specialized diet of tough plant materials.
10.
Australopithecus prometheus is also known as...
Correct Answer
A. Little Foot
Explanation
Australopithecus prometheus is commonly referred to as "Little Foot". This name is given to a fossilized skeleton of an early human ancestor that was discovered in South Africa. The name "Little Foot" is used to describe the small size of the foot bones found in the fossil, which is characteristic of Australopithecus species. The other options, "Big Foot", "Hair Ball", and "Hair Mass", are not accurate names for Australopithecus prometheus.
