Evolution Test Review (part 1)

Front

What is natural selection?

Back

Natural selection is the process by which organisms better adapted to their environment tend to survive and produce more offspring. It is a key mechanism of evolution.

Front

What is antibiotic resistance?

Back

Antibiotic resistance occurs when bacteria evolve and develop the ability to survive exposure to antibiotics that once killed them or inhibited their growth.

Front

How do mutations contribute to evolution?

Back

Mutations introduce genetic variation within a population, which can lead to new traits that may be advantageous for survival and reproduction.

Front

What evidence supports the theory of evolution?

Back

Fossil records, genetic similarities among species, and anatomical structures are key pieces of evidence that support the theory of evolution.

Front

What is phenotypic variation?

Back

Phenotypic variation refers to the differences in physical traits among individuals in a population, which can be influenced by genetic and environmental factors.

Front

What role do fossils play in understanding evolution?

Back

Fossils provide historical evidence of past life forms and their changes over time, helping scientists understand the evolutionary relationships between species.

Front

What is the significance of anatomical structures in evolution?

Back

Anatomical structures, such as homologous and analogous structures, help scientists determine evolutionary relationships and common ancestry among species.

Front

What is a common ancestor?

Back

A common ancestor is a species from which two or more different species have evolved, indicating a shared evolutionary history.

Front

How does natural selection affect a population over time?

Back

Natural selection can lead to changes in the traits of a population, favoring individuals with advantageous traits, which can result in evolutionary adaptations.

Front

What is genetic similarity?

Back

Genetic similarity refers to the degree of genetic overlap between different species, which can indicate how closely related they are in evolutionary terms.
