Final answer:
A dichotomous key for the given species was created, using the methodology of employing characteristics to differentiate between species. Evolutionary contexts were also considered in the process of creating the key.
Explanation:
A dichotomous key is a tool that allows anyone to determine the identity of items in the natural world such as trees, wildflowers, mammals, reptiles, rocks, and fish. Given your list of species: sea turtle, iguana, frigate bird, fruit bat, Galapagos tortoise, and hammerhead shark, a basic dichotomous key could look like this:
- 1. Animal has feathers (go to 2), Animal does not have feathers (go to 3)
- 2. Animal is frigate bird
- 3. Animal lives in water (go to 4), Animal does not live in water (go to 5)
- 4. Animal has a shell (sea turtle), Animal does not have a shell (hammerhead shark)
- 5. Animal has a shell (Galapagos tortoise), Animal does not have a shell (go to 6)
- 6. Animal has wings (fruit bat), Animal does not have wings (iguana)
Evolutionary concepts can also be applied when constructing a dichotomous key. Based on the evolutionary trees provided, the shark branched off first, indicating it's the most ancient animal among the given examples, followed by reptiles such as the iguana and tortoise, then birds like the frigate bird and finally mammals like the fruit bat.
