Evolution Survival Words
Evolution is a change in an organism over time.
Natural Selection is a non-random process where one member selects a mate with preferred traits.
Natural Variation is the random differences that occur within a species.
Fitness is the ability to survive and reproduce.
Adaptation is a change in an organism's behavior in response to an environmental change.
Survival of the Fittest is where only the species most fit will survive and reproduce.
Speciation is the process of evolution where new species are formed.
Species are different groups of population of a member (Birds: finches, swallows, gulls.)
Darwin is a famous naturalist who discovered evolution.
Mutations are changes in genetics which can be bad or good or neutral.
Acquired Traits are changes you get that are not caused by genes.
Isolating Mechanisms (Geographic, Behavioral, and Temporal Isolation) are features of behavior, morphology, or genetics which serve to prevent breeding between species.
Evolution Critical Questions
How do scientists explain how evolutionary change happens? Evolution was discovered by Charles Darwin. The evidence of evolution is seen by studying animal characteristics over short times and studying fossils to see how animals have evolved over long times. Speciation is the result of evolutionary changes. There is evidence of evolution in all species. For example, birds are similar to dinosaurs in their leg design and are thought to have evolved from dinosaurs. Our study of Darwin and evolution helped learn about evolution and how it was discovered. It is important for us to understand that species around us are continuing to evolve.
How can environmental factors affect the evolution of populations? In class, we studied how bird beaks can change over time based on what food is available for them to eat. Some environmental factors that affect the evolution of populations are food and water availability. Animals are known to have changed their size or shape to adapt to their new environment. Some animals change size to acquire food that other sized animals can't get, like a giraffe. Environments also change the desired traits of animals, which affects natural selection. Some may get a mutation or natural variation that increases its fitness, which gives them a desired characteristic and they will be more naturally selected by a mate. We did the bird beak lab in class to help understand how environmental factors can affect a bird's beak through evolution. What we do to our environment can affect the growth of a species.
