Question
Chapter 22.2, Problem 1CS
Summary Introduction
To propose: A model and characteristics of transitional form that is present between birds and dinosaurs.
Introduction: Fossils help in predicting the successive evolutionary change in an organism. The fossil provides information regarding different evolutionary changes in a series of related organisms. A transitional form depicts an intermediate state present between the ancestral form and the form of its descendants.

n.
Scientists have found one new fossil that is similar to Archaeopteryx. It is only the second fossil of its kind. It shows an animal that had a long-feathered tail and small teeth, like non-avian dinosaurs. But the animal also had flight feathers and wings, like modern birds. The fossil also shows a fused clavicle bone, which confirms the relationship between birds and dinosaurs because they are the only two groups with this characteristic.
What is true about this scenario?
It shows evidence of evolution.
It shows evidence of widespread expression.
It shows evidence of climate change.
It shows evidence of causation.

On the branches of the phylogenetic tree on the back side of this worksheet, write in a unique derived trait (Autapomorphy), either anatomical or behavioral, that is used to distinguish each primate subgroup from the other taxa of primates. The points where the derived traits should be entered are labelled A1 - A6 and a written description of what is expected for each appears below and to the right of the tree. 2. On the trunk of the phylogenetic tree write in a shared derived trait (Synapomorphy) that unifies the branches (clades) of the tree which sit to the right of the trait marker (S1-S5). Again these traits can be either anatomical or behavioral and a written description of what is expected for each appears below and to the right of the tree. For both #1 and #2 you should write in at least one trait for each trait marker (A1-A6 and S1-S5) that appears on the phylogenetic tree. Make sure all entries are detailed enough to differentiate taxa and written legibly. If…arrow_forwardDiscuss: How old are the oldest camel fossils shown? How has the skull changed over time?

- Regents Practice: Base your answer to question 1 on the information below. Ten years ago, scientists discovered a well-preserved set of dinosaur remains in China. This dinosaur, which walked on Earth about 125 million years ago, had feathers and was about the same size as a turkey - but don't be fooled. This dino's bite was a lot worse than a turkey's gobble. After a close (and careful!) examination of the dino's teeth, scientists recently concluded that this dinosaur was probably poisonous. The study was led by David Burnham, who works and teaches at the University of Kansas in Lawrence. Source: www.sciencenewsforkids.org 1. State one inference that could be made based on the fact that this dinosaur had feathers. 2.
