Genome-scale data resolve deep animal relationships, such as ctenophores versus sponges as sister group.
Molecular data reorganised animals into Lophotrochozoa, Ecdysozoa and Deuterostomia. Some questions persist: whether sponges or comb jellies branched first.
Large datasets reduce error but model misspecification may remain. Fossils calibrate trees. Disputes continue.
Key idea: genome data are rewriting animal family trees.

Animal Phylogenomics is one of the 53 topics in Zoology & Animal Diversity. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Vertebrates and Invertebrates, Animal Respiration, Hibernation and Torpor.
Tardigrades are ecdysozoans related to arthropods.
Work through the Beginner topics in Zoology & Animal Diversity first, such as Animal Kingdom, Vertebrates and Invertebrates, Sponges, then return to Animal Phylogenomics. Advanced topics assume the Intermediate vocabulary.
The closest topics to Animal Phylogenomics are Vertebrates and Invertebrates, Animal Respiration, Hibernation and Torpor, Protostomes and Deuterostomes. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Animal Phylogenomics. To practise the whole of Zoology & Animal Diversity, use the Zoology & Animal Diversity quiz.
Animal Phylogenomics: Genome-scale data resolve deep animal relationships, such as ctenophores versus sponges as sister group. Vertebrates and Invertebrates: Vertebrates have a backbone; invertebrates, which are over 95 percent of animals, do not. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Vertebrates and Invertebrates and explain the difference aloud. Finally, take the Zoology & Animal Diversity quiz and come back to this page for any question you miss.
