Shubin and Daeschler search in the Canadian arctic for fossil evidence of the transition from fish to tetrapods? They hypothesized that the transitional fossils were in sedimentary rocks older than 365 million years ago, when the first tetrapods appear in the fossil record. They hypothesized that the transitional fossils were in sedimentary rocks older than 530 million years ago, when the first fish appear in the fossil record. They hypothesized that the transitional fossils were in volcanic rocks older than 530 million years ago, when the first fish appear in the fossil record. They hypothesized that the transitional fossils were in volcanic rocks older than 365 million years ago, when the first tetrapods appear in the fossil record.
Answer:They hypothesized that the transitional fossils were in sedimentary rocks older than 365 million years ago, when the first tetrapods appear in the fossil record.
Experimentation (or the experiments the scientist was doing for 10 years) could be wrong or done in an inappropriate way. The only way to know if the information is valid is by checking the way the experimentation (data) was done as well as making sure to check all other factors
Fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Sporangium an important part of fungi are dispersed through a variety of means, such as being carred by wind, latching onto other organisms and even floating in wat
