What is a Population? A population is a group of the same organisms living in the same place at the same time.

He theorized that organisms change over time because specific traits allow an organism to survive and reproduce better. In other words, nature picked winning and losing traits. The winning traits became the dominant trait over time. Below are the 4 things that had to happen for natural selection to occur.

  • Fossils which provide evidence of how organisms have changed over time
  • DNA which allow us to compare the genetic code of organisms and draw conclusions about how they are related to each other
  • Similar structures such as similar bones point to organisms coming from a common ancestor
  • Embryology: the study of embryos hints that all animals with backbones evolved from a common ancestor that was like a fish
  • Evolution is happening right now: We see that bacteria have evolved to be resistant to antibiotics because of natural selection

         adaptations
       - an organism becomes
