The document discusses examples of uniformitarianism and the principles behind Darwin's theory of evolution, including the struggle for existence among organisms and the differences between artificial and natural selection. It highlights that present observations can provide insights into past events, such as canyon formation and species evolution. The text outlines key concepts related to population dynamics and natural variations affecting evolutionary processes.

Which of the following is an example of uniformitarianism- Present obs.pdf
- 1. Which of the following is an example of uniformitarianism? Present observations of erosion on a streambank demonstrate how a canyon was formed in the past. members of a natural population of finches that deviate from the norm are identified as "hopeful monsters". When choosing between competing hypotheses without other evidence, the simplest explanation is usually the most likely. The development of a fish embryo shows how vertebrates evolved from simpler invertebrates. The presence of a canyon is explained as having been generated from Noah's flood. From what observations did Darwin infer that there must be a struggle for existence among organisms? populations are capable of tremendous growth in numbers, but most natural populations persist in a steady state. limited resources function to keep natural population numbers stable. there is natural variation among individuals. all three of the choices are correct. two of the choices are correct. Artificial selection differs from natural selection in that with artificial selection, it is not possible to measure the selection differential none of the choices are correct natural selection occurs more rapidly because there are often multiple selective pressures on a population natural selection is more easily reversible than artificial selection artificial selection is easier to document
