The tree of life is growing faster than ever, Pg13

Key Highlights:

• Researchers analyzed databases of nearly 2 million named species dating back to the mid-1700s.
• Species additions have accelerated since 2015, with approximately 17,000 species named in 2020.
• Animals, arthropods, insects, beetles, and ray-finned fishes have gained about a fifth of their current species since 2000.
• Fungi, arachnids, crustaceans, and reptiles may contain up to 4x today’s diversity.

Detailed Insights:

• The study highlights the rapid pace of species discovery and classification in recent years.
• This acceleration could be attributed to advances in technology, increased research efforts, and greater accessibility of data.
• Understanding the diversity and distribution of species is crucial for conservation efforts and biodiversity management.
• Further research is needed to explore the potential implications of this rapid growth in the tree of life.

Scientific/Technical Concepts Involved:

• Arthropods: Invertebrate animals with an exoskeleton, a body, and paired jointed appendages.
• Ray-finned fishes: A class of bony fishes with fins supported by thin, flexible rays.
• Taxonomy: The science of classifying and naming living organisms based on shared characteristics.
