- Tiktaalik is a fish that lived 375 million years ago that grew to three metres long and had aquatic features mixed with others more suited to life on land. The fossils of five Tiktaalik specimens reveal that the animals had a large, robust pelvic girdle, a prominent hip joint, and long hind fins. The powerful fins could have propelled the beast in the water, but also helped it walk on riverbeds, or scramble around on mudflats. It is believed that Tiktaalik evolved into four- legged land animals. The scientists have yet to find a Tiktaalik hind fin bone, or any remains that might shed light on the origins of toes. A picture of Tiktaalik is available at https://www.npr.org/2010/07/05/127937070/t human-edge-finding-our-inner-fish Describe how Darwin would explain that evolution of hind legs (of land animals) actually began as enhanced hind fins (of Tiktaalik), referring to his relevant observations and inferences (Lecture 02 History of Evolutionary Thought - slide 18).

These animals have a tail and most of them are lungless. They respire through their skin or gills.

This required the ability to use the process of aerobic respiration to more efficiently break down food molecules.

- Imagine if mermaids are real. What are their biological and Physical demands (LOCOMOTION, BREATHING, and THERMOREGULATION)?arrow_forwardDinosaur and ancestral bird fossil data from the Triassic, Jurassic, and Cretaceous time periods were used to estimate body mass. Scientists are examining the connection between body mass, niche saturation, and extinction of species in the Triassic, Jurassic, and Cretaceous time periods. The terrestrial dinosaurs’ neck length and diet are compared to the evolution of the winged dinosaur through the three time periods. Which of the following statements best states the null hypotheses regarding winged dinosaurs? The greater number of herbivore dinosaurs throughout all the periods inhibited the evolution of winged dinosaurs due to a lack of available resources and habitat. A greater number of winged dinosaurs of the early Cretaceous period become extinct as fewer winged dinosaurs with greater body mass evolve to take over their niche. The extinction of long-necked herbivores in the late Jurassic period provided a greater amount of habitat and food resources for early Cretaceous…arrow_forwardDiscuss the trade-offs associated with the following life history traits: a.
