Nastasia [14]

inferred from the tree is described below.

Explanation:

Evolution

  • EXAMPLE ONE-It provides information about the organisms' habitats. It shows possible common ancestry between organisms. It provides information to determine the organisms' ages. It shows possible chromosomal similarities between organisms.
  • EXAMPLE TWO-According to fossil records, the horses that lived 50 million years ago were much smaller, weaker and slower than modern horses. commensalism  .inbreeding ,migration  and evolution by natural selection.
  • EXAMPLE THREE-The organisms share a common ancestry. The organisms belong to the same genus. The organisms are native to the same geographic areas. The organisms will grow into anatomically similar adults.
  • EXAMPLE FOUR-The jaws of hominids evolved to be smaller and less protruding over time.The jaws of hominids evolved to be larger and more protruding over time.There appears to be no change in the jaws of hominids over time. The jaws of hominids changed over time due to a change in brain size.
  • EXAMPLE FIVE-Species 1 is most closely related to Species 8. Species 2 is most closely related to Species 3. Species 3 is most closely related to Species 7. Species 5 is most closely related to Species 6.
  • EXAMPLE SIX- DNA sequences ,Anatomical features ,Habitat types  and Reproductive Strategies
