Which of the following would not support darwin's research leading to the theory of natural selection? vestigial structures are found in fossils of ancient ancestors and current related populations certain traits allowing individuals to survive are passed to offspring certain mutations that weaken individuals in a population eventually die out in future generations colored feathers that camouflage birds from predators are found in the majority of the current bird population

Recent research by marine biologists suggests that bottlenose dolphins have names for themselves. scientists played sounds they had identified as the names of particular dolphins, putting them through a synthesizer so that they did not sound like the voices of particular dolphins. the researchers found that dolphins would respond to the names of other dolphins that they were related to or associated with, but they ignored the names of strangers. this discovery suggests a much greater degree of self-awareness in aquatic mammals than was previously suspected. if this research holds up, what does it suggest about dolphins?
