Quiz on Human Evolution

The organs that have the same basic structure but different functions are called:

• Fossils

• Biogenetic law

• Homologous organ

• Analogous organ

Answer explanation

Homologous organs share a similar structure but serve different functions in different species, indicating a common evolutionary origin. Examples include the forelimbs of humans and whales.

The study of human evolution indicates that all of us belong to the single species that evolved in ………..

• West Asia

• Central Asia

• Africa

• America

Answer explanation

The study of human evolution shows that all modern humans originated from Africa, making it the correct answer. This is supported by fossil evidence and genetic studies tracing our lineage back to this region.

• Lucy

• Homo naledi

• Homo sapiens

• Australopithecine

Answer explanation

The most recent discovery in human evolution is the fossils of Homo naledi, which were found in South Africa and date back to about 236,000 to 335,000 years ago, providing new insights into our evolutionary history.

During which era did dinosaurs flourish?

• Proterozoic era

• Paleozoic era

• Cenozoic era

• Mesozoic era

Answer explanation

Dinosaurs flourished during the Mesozoic era, which is often called the 'Age of Dinosaurs.' This era is divided into three periods: Triassic, Jurassic, and Cretaceous, where dinosaurs were the dominant terrestrial vertebrates.

Which of the following is the idea that new species evolved due to their defined change?

• Natural selection

• Mutation

• Recombination

• Non-random mating

Answer explanation

Mutation refers to changes in the DNA sequence, which can lead to the development of new traits and ultimately new species. This process is a key mechanism of evolution, distinguishing it from other concepts like natural selection.

What is the process of creating a better adapted environment for organisms to survive and have more offspring?

• Natural selection

• Mutation

• Recombination

• Non-random matting

Answer explanation

Natural selection is the process where organisms better adapted to their environment tend to survive and produce more offspring. This leads to the gradual evolution of species, making it the correct choice for the question.

Who among the following is called 'Tyrant Lizard King'?

• Protoceratops

• Tyrannosaurus rex

• Diplodocus

• Compsognathus

Answer explanation

The 'Tyrant Lizard King' is a nickname for Tyrannosaurus rex, known for its size and predatory nature, making it one of the most famous dinosaurs.

What is the meaning of the scientific name Homo sapiens of humans?

• Erect hominid

• Large brend hominid

• Bipedal hominid

• Wise hominid

Answer explanation

The scientific name Homo sapiens translates to 'wise hominid.' 'Homo' means 'man' or 'human,' and 'sapiens' means 'wise' or 'discerning,' highlighting the cognitive abilities of humans compared to other species.

What is the meaning of the scientific name 'Homo sapiens'?
