Evolution hist p1

Why do paleontologist look for similarities in body structure when deciding whether species belong together?

• To determine if the species have a common ancestor

• to identify adaptive traits in the species

• to evaluate empirical evidence more carefully and precisly

• to understand the individual's survival likelihood

Why do more careful and precise observations provide stronger evidence in paleontology?

• they reveal adaptive traits of organisms

• the identify the body structures of common ancestors

• they help paleontologists determine species relationships

• they provide a deeper understanding of the individual's survival likelihood

Which statement? Best describes the common rules shared by science disciplines in obtaining and evaluating empirical evidence.  

• Science disciplines use different rules depending on the type of evidence. 

• Science disciplines have unique rules for obtaining and evaluating empirical evidence. 

• Science disciplines do not rely on empirical evidence to form conclusions. 

• Science disciplines share common rules for obtaining and evaluating empirical evidence.

What is an adaptive trait? 

• A trait that makes it more likely that an individual will survive in a specific environment. 

• A trait that helps paleontologists determine species relationships. 

• A trait that is unique to a particular species. 

• A trait that indicates the presence of a common ancestor. 

What does the term ancestor refer to in evolutionary history? 

• A related Organism from a previous generation. 

• An individual's survival likelihood in a specific environment. 

• A trait that makes it more likely that an individual will survive. 

• A body structure shared by different species. 

How is body structure defined in the context of evolutionary history? 

• It is a trait that indicates the presence of a common ancestor. 

• It is a unique characteristic of a particular species. 

• It is a related Organism from a previous generation. 

• It refers to one or more parts of an Organism, such as bones. 

Which of the following would paleontologists consider as a significant piece of evidence in determining species relationships? 

• The color of the organisms body structures. 

• The location where the organisms were discovered. 

• The similarities in body structures between species. 

• The size of the organisms adaptive traits.  

What do paleontologists primarily focus on when studying evolutionary history? 

• The size and weight of Organism.

• The age of the fossil remains discovered. 

• The relationships between different species.

• The geographical distribution of organisms.
