Cladogram and Phylogenetic Tree practice

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among a group of organisms, illustrating how species are related through common ancestors.

Front

What is a phylogenetic tree?

Back

A phylogenetic tree is a branching diagram that represents the evolutionary history of a group of organisms, showing how they have diverged from common ancestors over time.

Front

What characteristic do all jawed vertebrates share?

Back

All jawed vertebrates share the characteristic of having jaws, which allow them to grasp and manipulate food.

Front

What is the significance of a common ancestor in evolutionary biology?

Back

A common ancestor is a species from which two or more species have evolved, indicating a shared evolutionary history.

Front

How can you determine the relatedness of species using a cladogram?

Back

You can determine relatedness by examining the branching points; species that share a more recent common ancestor are more closely related.

Front

What are the three domains of life?

Back

The three domains of life are Bacteria, Archaea, and Eukarya.

Front

What is the difference between Archaea and Bacteria?

Back

Archaea and Bacteria are both prokaryotic domains, but Archaea have distinct biochemistry and genetics that differentiate them from Bacteria.

Front

What does it mean for organisms to be bi-pedal?

Back

Bi-pedal organisms are those that walk on two legs, a characteristic seen in humans and some other species.

Front

What is the role of complex brains in evolution?

Back

Complex brains allow for advanced behaviors, problem-solving, and social interactions, which can enhance survival and reproduction.

Front

What is binocular vision?

Back

Binocular vision is the ability to perceive depth and three-dimensional structure using both eyes, which is important for judging distances.
