Area of Science:

  • Evolutionary Biology
  • Genomics
  • Bioinformatics

Background:

  • Species divergence times are crucial for understanding biodiversity, development, and disease.
  • Molecular dating has significantly advanced the study of temporal patterns in species divergence.
  • The TimeTree resource provides a centralized, accessible database of species divergence times.

Purpose of the Study:

  • To report a major expansion of the TimeTree resource.
  • To increase the number of species and studies available in the database.
  • To enhance accessibility and visualization of evolutionary data for scientists and the public.

Main Methods:

  • Assembly of molecular sequence data from diverse species and genes.
  • Calculation of species divergence times using molecular dating techniques.
Keywords:

  • Development of new timetree and timeline visualizations.

    • Main Results:

    • The TimeTree resource now includes over 97,000 species, more than tripling its previous size.
    • The number of assembled studies has more than tripled, exceeding 3,000.
    • New visualizations allow access to timetrees of species groups and timelines of individual species' evolution.

    Conclusions:

    • The expanded TimeTree resource offers unprecedented access to molecular dating data.
    • Enhanced visualizations, integrated with geological history, improve understanding of biosphere evolution.
    • The resource serves as a vital tool for research in biodiversity, development, and disease, accessible to scientists, educators, and the public.
