These worksheets contain questions for each level and video of the Evolution Lab and provide assessment on topics like cladograms, fossil evidence of evolution, DNA and genetics, biogeography ...

If a population evolves through time without splitting into multiple branches it is called anagenesis (or, anagenetic evolution). Cladogram: a branching diagram that represents only phylogenetic ...

Cladistics is one way scientists classify organisms. A cladogram shows the nature of evolutionary relationships that may have occurred, similar to a family tree. You will make a cladogram in this ...

and it reinforces the evolutionary explanation for the illustrated relationships. As you can see, a number of modern animals—including birds—are depicted along the top of the cladogram in ...
