CAPTION: Hopi Hoekstra and colleagues wanted to test the hypothesis that
coloration of beach and inland mice (Peromyscus polionotus) provides camouflage
that protects them from predation in their respective habitats. The researchers

those of the beach and inland mice and then placed models with both patterns in

The species diversity of an evolutionary lineage will increase when more new
member species originate than are lost to extinction. In this hypothetical example,
by2millionyearsago,bothlineageAandlineageBhavegivenrisetofourspecies,
and no species have become extinct (denoted by a dagger symbol). By time 0,
however,lineageAcontainsonlyonespecieswhilelineageBcontainseightspecies.

CAPTION: The five generally recognized mass extinction events, indicated by red
arrows along thex-axis, represent peaks in the extinction rate of marine animal
families (red line and left vertical axis). These mass extinctions interrupted the
overall increase in the number of marine animal families over time (blue line and
rightverticalaxis).
