In the early 1970s, drs. peter and rosemary grant began studying darwin's finches and significantly extended our knowledge of the different species and their behaviors. on the island of daphne major, the grants focused on three closely related species within the genus geospiza. the table summarizes some of the distinguishing traits of each species. the grants did experiments that demonstrated that each species on daphne chooses mates of their own species over other species. on rare occasions, species will hybridize and create viable offspring, but this is extremely infrequent. the three species are still distinct enough that they are considered separate species. in 1981, a single bird appeared on daphne that was not any of the three species described above. the grants called him "5110." watch the video to learn more about 5110.

You decide that the introduction should also discuss the extremophiles that are referred to as the archaea. these single-cell organisms are considered "extremophiles" due to their ability to survive and reproduce in environmental conditions that would be hostile for most living organisms. archaea species have been isolated from highly acidic sulfur springs, ocean floor thermal vents with temperatures that exceed boiling, and subarctic ice well below freezing. while still considered to be prokaryotic, the archaea have numerous differences that place them apart from the bacteria. choose the characteristics that separate the archaea from other prokaryotic cells. select all that apply. view available hint(s) select all that apply. archaea lack true peptidoglycan in their cell walls. the morphology of the cell is rigid and is geometric in shape, similar to a sphere or cylinder. the cytoplasmic membrane lipids of archaea have branched or ringform hydrocarbon chains. all currently identified and characterized archaea have been linked as the causative agent to an animal or human disease.
