Fundamentals Of Evolutionary Biology

1. What is microevolution?

The idea that evolution only occurs at the macroscopic level and not at the microscopic level.

The theory that organisms evolve into entirely new species in a short period of time.

The belief that evolution is controlled solely by random chance and not by natural selection.

Microevolution refers to changes in allele frequencies in a population over time, which can result in the adaptation and specialization of a species. It does not involve the sudden emergence of new species, nor is it ruled by random chance alone.

Explanation

Microevolution refers to changes in allele frequencies in a population over time, which can result in the adaptation and specialization of a species. It does not involve the sudden emergence of new species, nor is it ruled by random chance alone.

2. What is macroevolution?

The idea that evolution only occurs through sudden, drastic changes in DNA.

The study of evolution on a small scale within a single population.

The theory that all organisms have evolved from a single common ancestor.

Macroevolution refers to large-scale evolutionary changes that take place over long periods of time. It is distinct from microevolution, which involves small-scale changes within a population. The correct answer highlights the transformative nature of macroevolution in shaping entirely new organisms.

Explanation

Macroevolution refers to large-scale evolutionary changes that take place over long periods of time. It is distinct from microevolution, which involves small-scale changes within a population. The correct answer highlights the transformative nature of macroevolution in shaping entirely new organisms.

3. What are strata?

A type of cloud formation.

Distinct layers of rock

A type of pasta dish.

A method of mathematical calculation.

Strata refers to distinct layers of rock that are formed over time through geological processes.

Explanation

Strata refers to distinct layers of rock that are formed over time through geological processes.

4. What are fossils?

Alien life forms discovered on other planets.

A type of mineral found underground.

Artifacts left behind by ancient civilizations.

Preserved remains of once-living organisms

Fossils are the preserved remains or impressions of once-living organisms that provide valuable information about past life on Earth.

Explanation

Fossils are the preserved remains or impressions of once-living organisms that provide valuable information about past life on Earth.

5. What is paleontology?

The study of economics.

The study of rocks.

The study of outer space.

The study of fossils

Paleontology is the study of fossils, including their development, relationships, and distribution in time and space. It does not cover the study of rocks, outer space, or economics.

Explanation

Paleontology is the study of fossils, including their development, relationships, and distribution in time and space. It does not cover the study of rocks, outer space, or economics.

6. What is structural homology?

The study of similar structures in different species

The study of contrasting structures in the same species.

The study of environmental influences on genetic expression.

The study of genetic variations within a species.

Structural homology refers to the comparison of similar structures across different species to understand evolutionary relationships and common ancestry.

Explanation

Structural homology refers to the comparison of similar structures across different species to understand evolutionary relationships and common ancestry.
