  1. 3. The preserved remains, impressions, or traces of once-living organisms, typically found in sedimentary rock. Fossils provide evidence of past life and can help scientists understand the history of life on Earth.
  2. 7. The supercontinent that existed during the late Paleozoic and early Mesozoic eras, around 335 to 175 million years ago, when Earth's landmasses were joined together before breaking apart into the continents we have today.
  3. 10. The geological principle that the processes that operated in the past (such as erosion and sedimentation) are the same as those observed in the present. This concept is fundamental in understanding Earth's geological history.

  1. 1. The process by which different kinds of living organisms have developed and diversified from earlier forms during the history of the Earth. It is driven by mechanisms such as natural selection, genetic drift, and gene flow.
  2. 2. America: A continent in the Western Hemisphere, located mainly in the Southern Hemisphere. It is a key region in the study of evolution, particularly with respect to the unique biodiversity found there.
  3. 4. Malthus: An English economist and demographer whose work influenced Charles Darwin. Malthus proposed that population growth would outpace food production, leading to competition for resources and natural selection.
  4. 5. Islands: A group of islands in the Pacific Ocean, located off the coast of Ecuador. The islands are famous for their unique wildlife and played a significant role in Charles Darwin's formulation of the theory of natural selection.
  5. 6. An extinct genus of large, armored mammals that lived during the Pleistocene Epoch. They were related to modern armadillos and had a shell-like armor covering their body.
  6. 8. A characteristic or behavior of an organism that has evolved over time to improve its chances of survival and reproduction in a specific environment.
  7. 9. Beagle: A British Royal Navy ship that Charles Darwin sailed on during his five-year voyage (1831–1836), during which he made many observations that led to the development of his theory of evolution by natural selection.
