Question

Which of these describes how traits are shown on a branching tree diagram? 1. The traits on the tree developed in organisms in random order. 2. All the traits on the tree developed at the same time. 3. Traits lower on the tree developed before traits higher on the tree. 4. Traits higher on the tree developed before traits lower on the tree.

Answer 1

Answer: 3.Traits lower on the tree developed before traits higher on the tree.

Step-by-step explanation: Image shows the order in which the traits develop over time. At the very beginning the trait for jaw developed. That is why all the animals present on the right-hand branch have jaws. Traits like the feather and hair came at the last, hence are present in the top branches.
