theory of evolution

Evolution

Change of species over time.

Scientific Theory

Well-supported explanation from multiple investigations.

Scientific Law

Well-supported description of observed phenomena.

Micro-evolution

Rapid evolutionary change in populations.

Fossil Record

Preserved remains showing ancient life and evolution.

Macroevolution

Evolution of groups larger than individual species.

Law of Superposition

Youngest rock layers are on top.

Homologies

Similarities due to common ancestry.

Structural Homologies

Anatomical similarities indicating evolutionary relationships.

Molecular Homologies

Similarities in DNA and proteins across species.

Embryonic Homologies

Similarities in embryos of different species.

Vestigial Structures

Remnants of structures that had important functions.

Convergent Evolution

Unrelated species develop similar traits due to environment.

Analogous Structures

Features in different organisms performing similar functions.

Biogeography

Study of species distribution over time and space.

Pangea

Supercontinent that explains species similarity across continents.

Direct Observation

Witnessing evolutionary changes in real-time.

Sedimentary Rock

Layered rock where most fossils are found.

Pesticide Resistance

Insects evolving resistance to chemicals like DDT.

Comparative Anatomy

Study of anatomical similarities and differences.

Comparative Embryology

Study of embryonic development across species.

Paleontology

Study of fossils to understand ancient life.
