18 Questions
What is the result of natural selection when survivors pass on their adaptations to offspring over time?
Distinct and reproductively isolated generation
Which type of mutation only affects a few base pairs and does not change the protein product of the gene?
Silent mutation
In what type of cells do somatic mutations occur?
Non-reproductive cells
How do mutations contribute to changes in the traits of organisms?
By affecting the shape of protein products
Which type of mutation can be inherited by the offspring in sexually reproducing organisms?
Germ line mutation
What happens if a germ line mutation leads to an advantageous trait according to natural selection?
Nature will increase its frequency in the population
What is the primary mechanism by which natural selection drives evolution?
Variation in traits, differential reproduction, and heredity
Which of the following is NOT a factor contributing to variation in traits within a population?
Intentional breeding by humans
What is the term used to describe traits that enhance an organism's ability to survive and reproduce?
Adaptations
Which of the following is NOT an example of an adaptation?
Intentional breeding by humans
What is the term used to describe the situation where not all individuals in a population can reproduce to their full potential due to environmental limitations?
Differential reproduction
Which principle of natural selection ensures that advantageous traits are passed on to future generations?
Heredity
What is the most widely accepted explanation for the diversity among organisms?
Theory of evolution by natural selection
What kind of evidence for evolution is directly observable or can be produced when desired?
Direct evidence
Which of the following is NOT an example of indirect evidence for evolution?
Observed instances of natural selection in action
What do paleontologists study?
Fossils
What is a transitional form in the context of evolution?
A species that possesses characteristics intermediate between those of an ancestral form and those of its descendants
What is artificial selection?
The process by which organisms with desirable traits are chosen by humans to reproduce
Explore the concept of natural selection, where nature determines which organisms survive to pass on advantageous traits. Learn how natural selection leads to evolution through variation, differential reproduction, and heredity.
