The image shows a modern ostrich next to a mononykus dinosaur. dinosaurs were reptiles. what conclusions can you draw about their evolutionary relationship? explain your response.

One is an ostrich, the other is a mononykus dinosaur. The structural relationship is obvious. Mononykus moved about on two legs, was very nimble, and could run at high speeds, something that would have been useful in the open desert plains where they lived. It had a small skull, and its teeth were small and pointed, suggesting that it ate insects and small animals, such as lizards and mammals.

Birds are to be believed to have evolved from bipedal dinosaurs called theropods around 150m years ago.

The modern-day ostrich and this dinosaur have the same basic shape. Reptiles and ostriches are both vertebrates, so they both have endoskeletons. Based on their shape, these organisms have a similar skeletal structure. Therefore, modern-day birds and the extinct dinosaurs share an evolutionary ancestor. However, the bird developed feathers and wings over time. These features must have evolved from a different ancestor. So, the ostrich has ancestors that the dinosaur does not have.

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
