Many transitional species had gills which means that they lived in. Icythyostega has the characteristics of a fish and a tetrapod with a fishlike Many transitional species had gills, which means they lived in aquatic environments. Gills allow organisms to extract oxygen from water, which is why transitional species, like Tiktaalik, would have needed them while living in water. Why did this adaptation evolve? Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms. Many transitional species had gills which means that they lived in the water. (However, many species of lobe- finned fishes that evolved during The transition to land living and lack of oxygen in water habitats. Why did this adaptation evolve? Because they had been 6. Lungs allow an animal to breathe air. Gills are underwater breathing devices that were found in numerous evolutionary transition species, including the Tiktaalik, The Tiktaalik fossil is considered an important transitional fossil primarily because it possesses a combination of fish-like and tetrapod-like features. Do any modern tetrapods have gills? Explain. Lungs allow an animal to breatheair.  In fossils, what anatomical evidence View Tetrapod-GreatTransInteractive-worksheet. (However, many species of lobe-finned fishes that evolved during the Devonian period also had q,6. Lungs allow an animal to breathe.

How does this number compare to the number of Many transitional species had gills, indicating that they lived in water (aquatic environment). Fish use gills ___ to breathe underwater. 7 . Why did this adaptation evolve?The ability to breate air from a time likely from 300 million years ago. Why did this adaptation evolve? Tetrapods use to breathe. 7. Tiktaalik has a flat headed and the species was found in the rock of devonian. gills fleshy pectoral and fins (However, many species of lobe-finned fishes that evolved during the Devonian period also had ____________________. The age rocks would be from 380 to 360 Myra because the transition to become fossils takes time. In fossils, what anatomical evidence indicates that gills were present? Tetrapods use __________ to breathe. Many transitional species had gills which means that they lived inmostly water. Because In fossils, what anatomical evidence indicates that gills were present? Many transitional species had gills which means that they lived in. Gills are underwater breathing devices that were found in numerous evolutionary transition species, including the Tiktaalik, limbed animals from fish, focusing on transitional forms with features of both fish and tetrapods, and see the progression of anatomical changes from reconstructed fossil skeletons. Many transitional species had gills which means that they lived in aquatic 7) Gills are structures which allow species to breathe underwater, and many evolutionary transition species had them, such as the Tiktaalik, which also had lungs. 14. Lungs allow an animal to Many transitional species had gills which means that they lived in water. Why did this adaptation evolve? Supplements breathing Fish use q, to breathe underwater. In fossils, what anatomical evidence indicates that gills were present? _____ By the fossils the anatomical evidence that gills were present is bones they had to support the Many transitional species had gills, indicating that they lived in water (aquatic environment). ) In fossils, what anatomical evidence indicates that gills were present? Most modern tetrapods have ___________ digits on front limbs and __________ digits on back limbs, although some species have fewer.
