Evolution
The process by which different kinds of living organisms develop and diversify from earlier forms during the history of the earth is called?
What is Evolution?
The process by which organisms better adapted to their environment tend to survive and produce more offspring is called?
What is natural selection?
A characteristic that helps an organism survive and reproduce in its environment is called?
What is an adaptation?
Who is Charles Darwin?
A naturalist known for his contributions to the understanding of evolution and natural selection.
This is the process by which species change over time due to environmental pressures and survival of the fittest.
What is natural selection?
Name one example of evolution
The development of antibiotic resistance in bacteria
Peppered moth", where moths living in polluted areas developed darker wings to blend in with the soot-covered trees.
Roaches resistant to bug spray
Name one factor that affects natural selection?
Competition for resources or mates,disease, or environmental changes.
Name an example of a physical adaptation.
The long neck of a giraffe, which helps it reach leaves high in trees.
Camouflage
A bird's beak shape: Adapted to the type of food it eats
A polar bear's thick fur: Helps insulate them in cold environments.
What book did Darwin write?
"On the Origin of Species."
These traits or behaviors increase an organism's chances of survival and reproduction.
What are adaptations
What is a fossil?
The preserved remains or traces of a once-living organism.
This refers to the idea that the individuals best suited to their environment are more likely to survive and reproduce.
Survival of the Fittest
How do adaptations help organisms survive?
They enable organisms to better exploit their environment and evade predators.
What were Darwin's main ideas?
Natural selection and the idea that all species of life have descended from common ancestors.
This term refers to the movement of genes into or out of a population through migration.
What is gene flow?
Describe a species.
A group of organisms that can breed and produce fertile offspring.
Explain how camouflage helps animals.
Camouflage allows animals to blend into their environment, making it harder for predators to spot them.
What is a behavioral adaptation?
An action or behavior that helps an organism survive, such as migration or hibernation.
How did Darwin study evolution?
Through observations of various species, particularly during his voyage on the HMS Beagle.
A random change in DNA that can introduce new traits to a population.
What is a mutation?
How do new species form?
Through processes like natural selection, genetic drift, and geographic isolation.
Describe the role of variation in natural selection.
Variation provides the raw material for natural selection, as it allows some individuals to be better suited to survive and reproduce in their environment.
Why are adaptations important for survival?
They allow organisms to better adjust to their environment, increasing their chances of survival and reproduction.
Why is Darwin important to science?
He proposed the theory of evolution by natural selection, which fundamentally changed our understanding of biological development.
A small population can lead to this, a random loss of genetic diversity.
What is genetic drift?
