Look at the graph of different types of vertebrates. Which evidence would support the relationships shown on this graph?
A graph shows evolution of four animal groups: amphibians, reptiles, birds, and mammals. A graph shows evolution of four animal groups: amphibians, reptiles, birds, and mammals. The y-axis is labeled Millions of years ago, starting with 300 millions of years ago, and decreases by increments of fifty millions of years ago to end at zero. The first line is labeled amphibians. It starts at 300 millions of years ago and goes to zero, or present day. The next line starts at 250 millions of years ago. The line splits at 225 millions of years ago and is labeled reptiles. At 200 millions of years ago, it splits into two lines labeled birds and mammals. Each line ends at zero, or present day.
