Name one fish like reptile that evolved from land reptile about 200 million years ago?
Step by step
Solved in 2 steps
- Your age-dating put the age of the rocks you are examining in the early Devonian period. Because of this, you suspect that the vertebrate remains you found might belong to some of the earliest tetrapods (four-legged animals including land vertebrates) to walk the Earth. Examine the cladogram below. What is the sister group to the land vertebrates? Lampreys Sharks Lungfish Land vertebrates Tetrapoda Choanata Fingers and toes Osteichthyes Choanae Gnathostomata Bony ribs and shoulder girdie Vertobrata Jaws O Lampreys Vertebrae O Tetrapoda O Amphibians Lungfish Ray-finned fish AmphibiansPick a specific animal that exists today and research its ancestor from millions of years ago. How has this animal evolved? Compare it to the ancestor and explain why certain changes may have taken place.Which of the following is true about the phylogeny of birds and reptiles. Question 35 options: a) Birds are more closely related to amphibians then they are to reptiles. b) Birds are a type of reptile, but are not related to dinosaurs. c) Birds and reptiles are the least related vertebrates. d) Birds are a type of reptile and are descended from a group of dinosaurs.
- Transitional species are species important in helping scientists determine the evolutionary path that species have taken over long periods of time. Lobe-finned fishes are the ancestors of amphibians and have fossils that are found in rocks that are at least 380 million years old. Fossils of the oldest amphibian-like vertebrate animals with true legs and lungs are found in rocks that are approximately 363 million years old. Paleontologists have found a sample of rock that is approximately 370 million years old which contains what seems to be a link between lobe-finned fishes and amphibians. Which of the following is a characteristic that you would not expect to see in this transitional fossil? Question options: Skeletal structures that indicate the development of legs. An intermediate structure between lungs and gills. Teeth that are intermediate to the lobe-finned fishes and amphibians. A neck that is more flexible than lobe-finned fishes.Why do penguins, seals, and tuna havesimilar body forms that permit rapid swimming? all share a common ancestor at some point in the past. all of their bodies have been compressed since birth by intensive underwater pressures. flying, pregnancy, and gill-breathing all require similar adaptations in form. the shape is a convergent evolutionary adaptation that reduces drag while swimming. this is the only shape that will allow them to maintain a constant body temperature in water.Amphioxus long has been of interest to zoologists searching for a vertebrate ancestor. Explain why amphioxus captured such interest and how it is different from the hypothesized most recent common ancestor of all vertebrates.
- How did the following fish groups evolve?a) Agnathab) Chondrichthyesc) Osteichthyesd) Tetrapodsces When Charles Darwin visited the Galapagos Islands, he observed the marine iguana. He later decided that the marine iguana evolved from the terrestrial iguana found on the mainland of South America. The marine iguana differs from the terrestrial iguana in several ways. The marine iguana has a flat tail, long claws and sharp teeth while the terrestrial iguana has a round tail, short claws and flat teeth. The marine iguana became a separate species after being geographically isolated on the Galapagos Islands for several years. What type of speciation is ne ds 1 and 2 Highschool MP3, this?* Adaptive O Allopatric Fri Sympatric O Geographic Next O OOn a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. Which big phylogenetic group of animals does this animal likely belong to? A. Ecdysozoa B. Lophotrochozoa C. Diploblasts D. Deuterostomes
- While hiking through the desert of New Mexico, the Smith family found a fish fossil. They thought it was strange to find something that belonged in the ocean in the desert. They each came up with a reason why there would be fish living in the desert. Who do you agree with and why?Which of the following is the most likely organism to fossilize and be found in the fossil record? The earliest forms of bacteria A jellyfish with a soft body An octopus with a soft body A crustacean with a hard exoskeletonConsider the following statement. Is it true or false? Why? Please justify your answer explaining the evolutionary process that took place using terms and concepts discussed in our lectures. Individual snakes had to evolve and adjust their mouth size to adapt.
