Fossil and molecular data reveal that laryngeal echolocation in bats evolved once in the common ancestor of all bats and was later lost in megabats. This finding clarifies bat evolutionary history.

Area of Science:

  • Evolutionary biology
  • Paleontology
  • Genetics

Background:

  • Molecular and morphological data are crucial for understanding evolutionary history.
  • Fossils offer unique insights into evolutionary transformations not always evident in living species.
  • Laryngeal echolocation is a key innovation in mammal evolution, particularly in bats.

Purpose of the Study:

  • To integrate molecular and paleontological data to resolve the evolutionary origins of laryngeal echolocation in bats.
  • To determine if echolocation evolved independently in microbats or in the common ancestor of all bats.

Main Methods:

  • Analysis of molecular data, including new sequences for the A2AB gene.
  • Incorporation of molecular phylogenies into parsimony analyses of morphological data.

Related Experiment Videos

  • Inclusion of morphological data from fossil bats (Eocene taxa: Icaronycteris, Archaeonycteris, Hassianycteris, Palaeochiropteryx).

    • Main Results:

    • Molecular data alone suggest microbats are paraphyletic but do not resolve the origin of echolocation.
    • Integrated analyses indicate laryngeal echolocation evolved in the common ancestor of fossil and extant bats.
    • Molecular dating estimates the last common ancestor of crown-group bats lived 52-54 million years ago.

    Conclusions:

    • Laryngeal echolocation evolved once in the ancestral bat lineage.
    • Megabats lost the ability of laryngeal echolocation after its initial evolution.
    • The integration of fossil and molecular data provides a more complete understanding of bat evolution.
