Animal behavioral diversity at risk in the face of declining biodiversity

Animal behavioral diversity at risk in the face of declining biodiversity

Our environment is changing rapidly, largely as a result of human activities, leading to a significant decline in biodiversity. According to researchers from the University of Victoria and the Max Planck Institute for Evolutionary Anthropology, this decline does not only affect animal life, but also our understanding of their behavior, including tool use. Our environment is…

Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesis

Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesis

Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first appeared is especially hard. However, ancient sediments and rocks hold chemical clues of available nutrients that could support the growth of bacteria. Microbial organisms dominate life on Earth,…
