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.
Based on the maximum body volume of organisms preserved in the fossil record, body volume (as measured in log mm )
has increased over the last 3.5 billion years. The trend in growth over time is depicted in the graph where the x-axis is a
measure of time in millions of years ago. Three boxes, each associated with a vertical dotted line that marks specific time
points along the x-axis, have been provided. Place a check mark in the boxes to indicate when drastic increases in
atmospheric oxygen are likely to have occurred.

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

Reptiles have a much lower specific metabolic rate than mammals.C. Predators tend to have very good binocular vision; prey animals tend to be able to see over a very wide angle.D.
