How can we explain that fossils of Mesosaurus, an extinct reptile that could not swim across open water, are found in the southern parts of both Africa and South America?
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.
Although most salamanders have four legs, a few species that live in shallow water lack hind limbs and have extremely tiny forelimbs (see photograph).Develop a hypothesis to explain how limbless salamanders came about according to Darwin’s mechanism of evolution by natural selection. How could you test your hypothesis?

Which one has the most species? When did the first vertebrates appear, and when did they first live on land? Where do we find the earliest fossils of vertebrates, and where do we find the earliest fossils of terrestrial (land-living) vertebrates? What are the following and how are they related to humans: Pongo, Gorilla, Pan, Sahelanthropus, Ardipithecus, Australopithecus, Homo erectus, and Homo neanderthalensis?

(1997), nautiloid and ammonoid shells with simple suture patterns could withstand great pressure but have poor buoyancy control whereas the opposite is true for those with complex suture patterns.Given the trend of increasing suture complexity over time in the shells of ammonoids (see figure on the right), how did their habitat change over time?arrow_forwardAmphioxus long has been of interest to zoologists searching for a vertebrate ancestor.

- 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.
