Evolution and Adaptations Lab # 6

1. Explain adaptive  radiation and how the different paper forms made by the "finches" helped or hurt that particular "finch species".

Adaptive Radiation is the relatively fast evolution  of many species from a single common ancestor. However, that happens when an organism enters a new area with lots of  ecological opportunity. "They found that different finch species can coexist if they have traits that allow them to specialize on particular resources. For example, two finch species, Geospiza fuliginosa and Geospiza fortis, vary in a key trait: beak size."

     2. Fill out the following table with your groups data at the end of the natural selection experiment

     3.With the prey survival data you collect, graph survivorship over time for each "species". There will be one graph for each candy type. Make sure you give your graphs titles and label units and axes.

      4. Explain how behavioral adaptations may lead to genetic changes in a population.

 The genetic variation in a population is linked from a wide range of genes and alleles. The persistence of populations over time through changing environments depends on their capacity to adapt to change external conditions.

1. A species that has a physical adaption that may allow its predator not to be able to eat it or find it. Explain what this behavioral adaption is.

Chameleon

The behavioral adaptation of chameleon is capable of changing color. The color changes help the animal to camouflage itself when predators are near.

2. A species that has a physical adaption that allows it to survive in cold weather.

Bear

 3. A species that has a physical adaptation that allows it to survive from its predators.

Cactus

  4. An example of mutualism in nature. Explain what mutualism is in this case.

Bees

Image from...

The bees get pollen to get nectar in order to survive and flowers benefit by getting bees to pollinate and sell as well as taking genetic information from other individual plant.

5. An example of commensalism in nature. Explain how your picture represents commensalism.

Clownfish

"Clownfish and Sea Anemones demonstrate mutualism because Anemones provide the Clown Fish with protection from predators whilst Clown fish defend the Anemones from Butterfly fish who like to eat Anemones." Info from...

6. An example of mimicry in nature. Explain what the mimicry is in this case.

Butterfly

Visual mimicry is a textbook case of natural selection because it is both intuitively understandable and has repeatedly evolved in a range of organisms: it is the ultimate example of parallel evolution. In many mimetic groups, particularly butterflies, a huge variety of colour patterns has arisen, even in closely related species. Info from...

7. One species from your country (plant animal insect etc.) that has an adaptation that lets it survive in your country. Explain.

Cactus in Haiti

Picture from...

Those cactus located in northern part of Haiti (Savann dezole).  During the day capture the sun energy for photosynthesis, and at night started to fix carbon dioxide, sugar, and other carbohydrate. They protect themselves against predator.
