A mechanism for change in populations.. Any change in the . inherited . traits within a population across generations. Individuals better adapted to their environment tend to survive and . produce more offspring. We have a reliable method for determining the age of rocks and fossils. .. As a result we know:. The Earth and the solar system are 4.6 billion years old.. The oldest fossil organisms on Earth (bacteria) are 3.5 billion years old.. What do we use in order to determine evolutionary relationships?. Fossil Record. Anatomical Evidence. Molecular Evidence. Embryological Evidence. Evidence for Evolution. Fossil Record. Evidence for Evolution. Biochemistry. Evidence for Evolution. Darwin Predicted:. Because new species form from existing species, there should be intermediate stages found in the fossil record..

PRESENT DAY. How are inheritable traits passed?. How do variations appear?. Today’s understanding of genes, DNA, variation, and mutations is central to our understanding of how evolution works .
