Background For Teachers:
In his studies he summarized a list of observations.
Traits are passed down from parent to offspring through DNA. Sections of DNA that code for a particular trait are called genes. These genes can code for a variety of traits in the offspring. Genes that help an organism survive will allow the organism to reproduce and more offspring will carry the advantageous gene of the parents. Genes that hinder an organism’s survival will reduce the ability of it to reproduce and then the gene will slowly become less prominent in the gene pool.
Darwin studied finches and observed that on each island the finch’s food source was different. Over time, the finch population on each island changed and evolved towards successful adaptations to their food source. This occurred because the finches best adapted to their food source had their DNA more represented in the gene pool.
this lab, color and its ability to blend into an environment is the trait that will be followed
through three generations. As the abundance of each color changes within the three
generations their population of color chips will change over time. This change in a
population over time is called evolution.
