O lung fish A. frogs B. birds C. mammals D. snakes How do capillaries differ in the brain compared to the rest of the body? A. do not pick up CO2 B. have an extra layer of connective tissue C. are not leaky D. do not have valvesarrow_forwardIn 1822, an Arkansas farmer discovered a fossil when a hill collapsed on his property. The farmer sent the bones to the Philadelphia society to be reviewed by scientists where it was determined that the bones were from a whale. Through research, the scientists discovered whales have a vestigial structure that includes a pelvic girdle and hind limbs. Which evidence best supports the theory that organisms, such as whales, have common ancestry and have evolved? Select all that apply. Group of answer choices A/Ostriches and emus are flightless birds. B/Ancient cave paintings depict humans and bulls thousands of years ago. C/More than 96% of human DNA is identical to chimpanzee DNA. D/In the early stages of embryonic development, humans, rabbits, fish, and salamanders look very similar. E/Scientists discovered eight genetic variants in four regions of the human genome that influence skin color ranging from very light to very dark.arrow_forward
- Give an example of an animal that has evolved through time such as birds, insects and others. How has this certain animal evolved? You may draw the evolution or simply explain. Thanks so much!arrow_forwardEvery extant animal has had to adapt to its environment in some ways over many generations. Think about an animal, its physiological features, and its environmental challenges. describe what features have likely had to adapt to its environment over time, and hypothesize what ways it might have to adapt to environmental changes in the futurearrow_forwardPakicetus is an ancient wolf-like organism that lived 50 million year ago. It had wolf-like ears and nostrils on the front of its skull. Modern whales have a similar ear structure, but their nostrils are on the back of their skull. Aetiocetus lived 25 million years ago, had the same ear structure as both Pakicetus and modern whales, but nostrils in the middle of its skull. According to this information, the most likely conclusion that biologists could draw about the relationship of Aetiocetus to the other organisms is that Aetiocetus...arrow_forward
- Adaptation and Evolution If you were to present that theme, which representative organisms would you use as example and why?arrow_forwardWhich of the animals represents the oldest creatures in terms of evolutionary historyarrow_forwardLampreys are jawless fish. Which conclusion about lamprey evolution is supported by the evidence in the diagram? A. Lampreys developed after hinged jaws formed. B. Lampreys once had hinged jaws but lost them during evolution. C. Lampreys are invertebrates and could not develop hinged jaws. D. Lampreys diverged from other vertebrates before hinged jaws evolved.arrow_forward
- Flight in birds developed over time due to multiple evolutionary steps. The development of feathers, hollow bones, large flight muscles, and efficient gas exchange was vital for flight. Describe the order in which these adaptations likely evolved and explain your reasoning.arrow_forwardThere are many common misconceptions about evolution. Which is TRUE about whale evolution? Early ancestors of whales evolved blowholes because they needed to breathe in the water. Whales are descended from monkeys. Modern whales are perfectly adapted to an aquatic lifestyle. The traits found in whales represent modifications of previous features that were found in their ancestors. Baleen whales evolved their distinctive filter feeding structure by chance.arrow_forwardFrom the evolutionary point of view, which one of the following is closer to man? A. DolphinB. Flying fishC.
