The Evidence Of Evolution

2.

Organs that have a similar structure in different species but have different functions are called what?

Vestigial organs
Homologous structures
Embryos
Fossils

Correct Answer

A. Homologous structures

Explanation

Homologous structures are organs that have a similar structure in different species but have different functions. These structures indicate a common ancestry and evolution. They may have adapted to perform different functions in different species, but their underlying structure remains similar. This similarity is evidence of a shared evolutionary history and supports the theory of evolution. Vestigial organs, on the other hand, are organs that have lost their original function over time. Embryos and fossils are not specifically related to organs with similar structures but different functions.

A horse has small toe bones behind its hoof, under the skin. They have no purpose or function. What kind of organs are they?

Vestigial
Homologous
Adaptive
Radioactive

Correct Answer

A. Vestigial

Explanation

The small toe bones behind a horse's hoof, which have no purpose or function, are known as vestigial organs. Vestigial organs are remnants of structures that were once functional in an ancestor but are now reduced in size or have lost their original function in the current organism.

Radiometric dating is a method used to do what?

Determine what kind of sediment is in rocks
Determine how much radiation is in an organism
Find the age of a fossil
Locate fossil deposits

Correct Answer

A. Find the age of a fossil

Explanation

Radiometric dating is a method used to find the age of a fossil. It relies on the principle that certain radioactive isotopes decay at a known rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a fossil, scientists can calculate how long it has been since the organism died. This technique is crucial for understanding the timeline of Earth's history and the evolution of life on our planet.

Which one of the following is NOT a type of fossil?

Cast
Trace
Whole body in amber
Dried leaf in mud

Correct Answer

A. Dried leaf in mud

Explanation

A dried leaf in mud is not considered a type of fossil because for a material to become a fossil, it needs to undergo a specific process called fossilization. Fossilization involves the preservation and replacement of organic material with minerals over a long period of time. In the case of a dried leaf in mud, it may leave an impression or imprint in the mud, but it does not undergo the necessary processes to become a fossil.

Which one of the following species belongs to the Great Apes?

Lemur
Human
Spider monkey
Gibbon

Correct Answer

A. Human

Explanation

The correct answer is human because humans belong to the Great Apes group. Great Apes are a family of primates that includes orangutans, gorillas, chimpanzees, and bonobos, as well as humans. Humans share a common ancestor with these species and have many similarities in terms of anatomy and behavior.

7.

Which one of the following animals is NOT a primate?

Lemur
Monkey
Kangaroo
Human

Correct Answer

A. Kangaroo

Explanation

A kangaroo is not a primate because it belongs to a different taxonomic group called marsupials. Primates include lemurs, monkeys, and humans, as they share common characteristics such as forward-facing eyes, grasping hands and feet, and complex social behavior. Kangaroos, on the other hand, have distinct characteristics like hopping locomotion, a pouch for carrying their young, and a different anatomical structure.

Lucy was a fossil of a very early hominid. Was Lucy a primate?

Yes, because all hominids are primates.
No, because hominids are not primates.
There's not enough information to tell.
Maybe. It depends on which scientist you ask.

Correct Answer

A. Yes, because all hominids are primates.

Explanation

The correct answer is "Yes, because all hominids are primates." This is because hominids, which include humans and their extinct ancestors, are a subgroup of primates. Primates are a group of mammals that includes humans, apes, monkeys, and prosimians. Since Lucy is described as a fossil of a very early hominid, she would also be classified as a primate.

Which one of the following was NOT an early primate species?

Australopithicus africanus
Homo erectus
Homo habilis

Correct Answer

A. Rana pipiens

Which one of the following is a fossil?

A bone dug from a 200-year-old gravesite
A Native American arrowhead
A 10,000-year-old footprint of a Woolly Mammoth
A chicken bone from KFC you find in your yard

Correct Answer

A. A 10,000-year-old footprint of a Woolly Mammoth

Explanation

The correct answer is a 10,000-year-old footprint of a Woolly Mammoth. Fossils are the preserved remains or traces of ancient organisms that lived in the past. The footprint of a Woolly Mammoth qualifies as a fossil because it is a trace left behind by an ancient organism. The bone dug from a 200-year-old gravesite and the Native American arrowhead are artifacts left behind by humans and not fossils. The chicken bone from KFC found in your yard is a modern bone and not a fossil.
