Which statement best describes the process of evolution?

The traits of a species can change over time

Populations can survive in different locations on Earth

Modern whales developed their traits through natural selection. What occurs during natural selection?

Only the fittest organisms can survive and reproduce

Organisms choose mates from other species to create new species

Breeders selectively cross organisms with desired traits

What does the fossil record tell scientists?

Only dinosaurs have formed the fossils scientists have discovered

There are very few organisms that have gone extinct

Which of the following best describes the concept of 'natural selection'?

A process where organisms better adapted to their environment tend to survive and produce more offspring

A random change in the DNA sequence

The movement of individuals from one population to another

The intentional breeding of organisms for desired traits

What does the term 'speciation' refer to in evolutionary biology?

The formation of new and distinct species in the course of evolution

The adaptation of a species to its environment

The genetic variation within a population

Which of the following statements is true about genetic mutations?

They are the primary source of genetic variation

They always lead to harmful effects

They occur only in response to environmental changes

How does the fossil record support the theory of evolution?

It provides evidence of gradual changes in species over time

It shows that all species have remained unchanged over time

It proves that humans evolved from modern apes

It shows that species appear and disappear randomly

What is the significance of homologous structures in different species?

They indicate a common ancestry

They are structures that have the same function but different origins

They are structures that have different functions but similar origins

They are structures that have no function

Which of the following best explains the concept of 'adaptive radiation'?

The process by which a single species evolves into several different forms that live in different ways

The gradual change of a species over time

The extinction of a large number of species within a short period

The process by which unrelated organisms independently evolve similarities

What role do environmental changes play in the process of natural selection?

They determine which traits are favorable and thus influence which individuals survive and reproduce

They create new species instantly

They have no effect on natural selection

They cause all individuals in a population to evolve simultaneously
