Natural Selection

The concept of interdependence in an ecosystem and its effect on the evolution of populations is further explored through a model of a dam. Students build a dam in the middle of the field, dividing the ecosystem in half to illustrate the affects of geographic isolation. They watch as the grass and then the rabbit populations in that region shift to one variant in the population. When students remove the dam, they observe the ecosystem slowly return to its original state. (less)

In this unit, we describe the theory of evolution by natural selection as proposed by Charles Darwin in his book, first published in 1859, On The Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life. We will look at natural selection as Darwin did, taking inheritance for granted, but ignoring the mechanisms underlying it. (less)

This lesson is an introduction to natural selection and is suited to any student who is just beginning his or her discovery of evolution. The motivation introduces a species of bird that became (over millions of years) numerous species, through adaptation. The development is a hands-on activity that demonstrates how populations change little by little, generation by generation, due to survival of species that have traits that are beneficial in an environment.

In this report, biodiversity and its relevance to the ecosystems that support humanity is discussed. Ecosystem functioning is defined as the collective activities of all biota within an ecosystem and how they affect its chemical and physical factors; therefore, it can be negatively impacted by decreases in biodiversity-the wide variety of life forms inhabiting the planet. The ecological and economic consequences of losses in biodiversity are explained. Additionally, case studies of scientific efforts to understand ecosystem functioning and to assess biodiversity are presented. Issues in Ecology is an ongoing series of reports designed to present major ecological issues in an easy-to-read manner. This Issue summarizes the consensus of a panel of scientific experts based on the information that was current and available at the time of its publication in 1999. (less)

This classroom activity introduces the concept of natural selection and how it relates to evolution. Students will use a variety of utensils including clothespins, tweezers and spoons to mimic animals with differently shaped mouths. The class will go through several trials, picking up at least twenty beans in one minute with their assigned utensil. If they fail to do so, their creature has died, demonstrating what happens to animals that cannot compete in the wild. Several discussion questions are included along with the activity. (less)

The issue-focused interview demonstrates how natural selection is a very efficient, predictable mechanism of evolution. It illustrates how species adapt to their environment, the reproductive success of a species, design in nature and presents evidence of evolution in action, e.g., antibiotic resistance. (less)

Coastal Climate Change

As climate changes, dynamic coastal regions are experiencing a wide range of impacts. Sea levels, ocean acidification, sea surface temperatures, ocean heat, and ocean circulation have all been changing in ways unseen for thousands of years. Arctic sea ice melted significantly more during summers in the last 30 years, and storms are intensifying. Coastal ecosystems stand to be damaged, and coasts will likely erode from rising sea levels, intensified storm surges, and flooding that climate change may amplify. Coastal communities will need to prepare adaptation strategies to cope, and many who live or work in coastal regions are wondering what climate change might mean for them. This module provides an overview of the impacts coastal regions are experiencing and may continue to experience as a result of Earth’s changing climate. A video series within the module demonstrates effective strategies for communicating climate science. (less)

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species. Use this activity to explain the role of pollution and how humans can impact populations as well as compare natural selection to the development of antibiotic resistance in bacteria, which occurs much more quickly.
