  • Our Voice. Fish can’t talk, but they do have gills—and that’s where our voices come from.
  • Sense of Hearing. How did gills become part of the ear?

What are some pieces of evidence for human evolution List 3?

Evidence for evolution

  • Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
  • Molecular biology. DNA and the genetic code reflect the shared ancestry of life.
  • Biogeography.
  • Fossils.
  • Direct observation.

What species did humans evolve from?

KEY FACTModern humans originated in Africa within the past 200,000 years and evolved from their most likely recent common ancestor, Homo erectus. Modern humans (Homo sapiens), the species? that we are, means ‘wise man’ in Latin.

What are the best evidence of evolution?

Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent. Nowhere on Earth do we find, for example, mammals in Devonian (the age of fishes) strata, or human fossils coexisting with dinosaur remains.

What are some pieces of evidence for evolution?

Five types of evidence for evolution are discussed in this section: ancient organism remains, fossil layers, similarities among organisms alive today, similarities in DNA, and similarities of embryos.
