Questions and Answers

What is the central theme emphasized in the text?

  • The use of the increasingly stable phylogenetic framework of the animal kingdom as the basis for understanding the pattern and process of physiological evolution.
  • The use of the increasingly stable phylogenetic framework of the animal kingdom as the basis for understanding the pattern and process of morphological evolution. (correct)
  • The use of the increasingly stable phylogenetic framework of the animal kingdom as the basis for understanding the pattern and process of behavioral evolution.
  • The use of the increasingly stable phylogenetic framework of the animal kingdom as the basis for understanding the pattern and process of ecological evolution.

    • What information do phylogenetic trees contain regarding species relationships and divergences?

  • Trees contain information on the relationships between species and the non-uniformity of genetic evolution, but not the timing of divergences.
  • Trees contain information on the relationships between species, the timing of divergences, and the non-uniformity of genetic evolution. (correct)
  • Trees contain information on the relationships between species and the timing of divergences, but not on the non-uniformity of genetic evolution.
  • Trees do not contain any information on the relationships between species, the timing of divergences, or the non-uniformity of genetic evolution.

    • What is the next step after mapping characters onto accurate trees?

  • Collaborating between morphologists, developmental biologists, comparative genomicists, palaeontologists and phylogeneticists. (correct)
  • Developing more sophisticated methods for mapping characters.
  • Determining character state homology.
  • Overcoming the potential for convergent evolution, character loss, and character state reversion.
