Study Notes
Key Vocabulary in Evolution
-
Adaptations: Refers to behaviors or physical characteristics that enhance an organism's ability to survive and reproduce within its specific environment.
-
Evolution: Represents the gradual transformation of species over extended periods, resulting in changes in physical and genetic traits.
-
Natural Selection: A critical process in evolution wherein individuals that possess traits better suited to their environment have a higher likelihood of surviving and reproducing.
-
Diversity: Indicates the wide variety of organisms that exist on Earth, highlighting the richness of life in different habitats.
-
Charles Darwin: A British naturalist renowned for formulating the theory of evolution through the mechanism of natural selection, significantly influencing biological sciences.
-
Variation: Captures any differences observed among organisms belonging to the same species, which can be crucial for natural selection.
-
Extinction: Describes the complete disappearance of all members of a particular species from the Earth, representing an end point in the evolutionary process.
-
Missing Links: Refers to gaps in the fossil record where transitional forms that could illustrate the evolution between different species have not been found.
-
Homologous Structures: Denotes anatomical features that are similar across different species, inherited from a common ancestor. Examples include the bones in a bird's wing, a dolphin's fin, and a dog's leg.
-
Fossils: The preserved remnants or impressions of organisms that existed in the past, serving as crucial evidence for understanding evolutionary history.
-
Radioactive Dating: A scientific technique used to determine the age of fossils by measuring the decay of radioactive isotopes found in surrounding rocks, providing insights into the timing of evolutionary events.
-
Mutations: Any alteration in an organism's DNA, which can create new traits and contribute to genetic diversity essential for natural selection and adaptation.
