Topic: NATURAL SELECTION ACTIVITY
Simulate a case of natural selection in a predator-prey situation.
STEP 1 Gather your materials. You should have:
. 1 fork, 1 knife, 1 spoon, and a length of tape (each will be used toestablish the distinct predator "feeding apparatuses")· 4 cups (each will serve as a distinct predator's "mouth")· 3 types of prey (such as popcorn, macaroni, and kidney beans)· 1 clearly delineated habitat (such as a table, a box, or a roped-off areaof ground). 1 timer that allows for counting by seconds (such as a watch or cellphone)
STEP 2 Set up the predators. There is variation in predatory feeding apparatuses in this population. You will choose one of the available predator feeding apparatuses: fork, spoon, knife, or four fingers (with your thumb taped to your hand so that you cannot use it). You will also take a cup, which will represent the predator's mouth. Your goal will be to use your feeding apparatus to collect food and put it inyour mouth.
STEP 3 Set up the…
. Structure and function is a central theme to the study of biology. Each major group of
organisms has evolved its own body part “tool kit" – a collection of structures that have
evolved in ways that make specific functions possible. From capturing food to digesting
it, and from reproducing to breathing, organisms use structures that have evolved into
different forms as species have adapted to life in different environments. The structure
of wings, for example enable birds and insects to fly. The structures of legs enable
horses to gallop and kangaroos to hop.
a. Think about your own teeth. What kinds of foods do you think human teeth are
suited for?
b. List at least three ways the structure of human teeth serves the function of
eating these food materials.
c. Now, finally apply the theme of structure and function to something you're very
familiar with - your hands. List out all the ways you can think of that the
structure of your hands serve the function of your hands.

However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.arrow_forward
- Activity: Factors involved in Natural Selection / Interpreting X-Y graphs The boldness of bass A recent study of largemouth bass, a type of freshwater fish, showed that individual fish have distinct personality types. The researchers looked at a fish's willingness to explore a new environment, which they called boldness. A more bold fish is one that will readily explore when placed in a new setting. Their study considers if boldness may be an adaptive trait, that is, subject to natural selection. The researchers therefore looked at the correlation between parent and offspring boldness scores, as shown in the figure. A. What pattern is illustrated by this figure? What factor(s) necessary for natural selection are shown in this graph? The association between the boldness scores OF Parents & Children is depicted in the image.

Compliment Connect Comment Question Generalized and specialized characteristics refer to different types of traits observed in organisms, particularly in the context of adaptation to specific environments or ecological niches. Generalized Characteristics: Generalized characteristics are traits that are relatively simple, flexible, and adaptable to a wide range of environments. Organisms with generalized characteristics are often referred to as generalists because they can thrive in diverse habitats and ecological conditions. Examples of generalized characteristics include a broad diet, moderate body size, generalist feeding habits, and behavioral flexibility. These traits allow organisms to exploit a variety of resources and habitats, enhancing their adaptive potential in unpredictable or changing environments. Specialized Characteristics: Specialized characteristics are traits that are highly adapted to specific environmental conditions or ecological niches. Organisms with…arrow_forward
