Chapter 20.3, Problem 1CC
Summary Introduction
To distinguish:
A particular clade of mammalian within the larger clade that corresponds to class mammalia and would hair be a useful character.
Introduction:
The group of organisms that share common ancestor and all descendants with representation of a single branch on phylogenetic treeis known as clade. This approach over the few years has revolutionized the classification of biology and evolutionary relationships between organisms.

- A study inferred a maximum likelihood phylogenetic tree based on sequence data from a specific gene. Numbers represent bootstrap support values for each clade. Based on the study's findings, how certain should we be that marsupials are sister to placental mammals, rather than monotremes? What number is used to represent this certainty, and how was it calculated?arrow_forwardHow can true seals be differentiated from the eared seals (sea lions and fur seals)?arrow_forwardThere are two main groups of bats: Smaller “microbats” navigate by using sonar, and larger “megabats” rely on vision. Mammalogists once though that both kinds of bats evolve from insectivorous mammals. But similarities between the visual systems of megabats and primates have led some researchers to think that megabats may have evolve from primates, perhaps lemurs. What results would support the hypothesis that the two groups of bats have a common origin? Separate origins?arrow_forward
