18 Questions
What is the simple definition of evolution?
Descent with modification
Explain the role of natural selection in evolution.
Facilitating individuals with better traits to withstand environmental challenges and produce offspring in the next generation.
What is the significance of ancestral cat species in the study of evolution?
It is where all of the cat family originated.
Define a gene and its role in determining an organism's traits.
A gene is a short DNA segment encoding for protein, which in turn determines an organism’s traits.
What is a population in the context of evolution?
A group of interbreeding organisms of the same species.
Why is the evolution of resistant pest populations significant in agriculture?
Over 500 pest species today have evolved resistance to at least one pesticide in 40 years.
What impressed Darwin during his visit to the Galapagos Islands?
Variability in the appearances of single species
What is the main idea behind the Theory of Evolution presented by Darwin and Wallace in 1858?
Natural selection
What monumental manuscript did Darwin publish in the following year after his stay on the Galapagos Islands?
On the Origin of Species by Means of Natural Selection
What two essential concepts did Darwin and Wallace's legacy include?
Descent with modification and natural selection
What idea did Alfred Russel Wallace devise to support what he saw during his voyage?
Theory of natural selection
What was the mechanism proposed by Darwin and Wallace to ensure the survival and reproductive success of individuals?
Natural selection
What term did Darwin coin to describe the mechanism by which certain traits are favored in a population over generations?
Natural selection
According to Darwin, why are some individuals more likely to survive and reproduce in their local environment?
Because their hereditary characteristics favored them to cope more efficiently in their environment.
What type of characteristics can be inherited and help organisms be better fitted to their environment?
Physical, physiological, or behavioral characteristics.
What are some examples of inherited traits or adaptations mentioned in the text?
Antibiotic resistance, a giraffe’s long neck, or short horses.
What factual basis did Darwin observe that led to his conclusion about natural selection?
Variations within a population and individuals producing more offspring than the environment can support.
Why do biologists still accept Darwin’s principle of natural selection today?
Because it explains how evolution occurs in nature.
Test your knowledge on the important factual basis from Darwin's observations that led to far-reaching conclusions still standing today, such as variations within a population and natural selection. Explore how Darwin concluded that individuals with advantageous hereditary characteristics cope more efficiently.
