Dr. Neil Shubin\u2019s discovery of Tiktaalik: <\/p>\n\n\n\n
options: A) occurred when he was looking for fossils of primitive man. B) was an entirely chance encounter. C) provided an example of an animal with some of the features of an amphibian and some of a fish. D) provided an example of an animal that was certainly the ancestor of all modern vertebrates.<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is C) provided an example of an animal with some of the features of an amphibian and some of a fish.<\/strong><\/p>\n\n\n\n Dr. Neil Shubin’s discovery of Tiktaalik<\/em> is one of the most significant fossil finds in the study of vertebrate evolution. In 2004, Shubin and his team found the fossil of Tiktaalik roseae<\/em> in the Canadian Arctic. This discovery was crucial because Tiktaalik<\/em> represents a transitional species between fish and the first land-dwelling vertebrates, known as tetrapods. The fossil exhibits features of both groups, which is why it is often described as a “fishapod.”<\/p>\n\n\n\n From the fish side, Tiktaalik<\/em> had gills and fins, characteristic of aquatic life. Its fins, however, had structures resembling bones and joints similar to the limbs of tetrapods. These fin bones allowed Tiktaalik<\/em> to support itself in shallow water or even on land, indicating that it might have been capable of limited movement on land. On the amphibian side, Tiktaalik<\/em> had a flat, wide skull, and its features suggest it could raise its head above the water, a necessary trait for land survival.<\/p>\n\n\n\n This discovery provided a key piece of evidence for the theory that vertebrates made the transition from water to land approximately 375 million years ago. Tiktaalik<\/em> shows intermediate characteristics that help explain how fish evolved into early land-dwelling animals. Its anatomical features illustrate a crucial moment in the evolutionary history of vertebrates.<\/p>\n\n\n\n While the discovery was not a chance encounter, it was based on years of targeted research in specific geological layers. However, Shubin was not searching specifically for fossils of primitive man, so option A is incorrect. Similarly, while Tiktaalik<\/em> provides insight into vertebrate evolution, it is not the direct ancestor of all modern vertebrates, so option D is also not accurate.<\/p>\n","protected":false},"excerpt":{"rendered":" Dr. Neil Shubin\u2019s discovery of Tiktaalik: options: A) occurred when he was looking for fossils of primitive man.
