cross-species comparisons

Cross-species comparisons involve studying different species—like humans, animals, or plants—to find similarities and differences in their biology, behavior, or genetics. Researchers do this to understand how certain traits or functions have evolved or are shared across species. For example, comparing the DNA of humans and chimpanzees reveals insights into common ancestry. This approach helps scientists learn about health, development, and evolution by examining how different living beings are related and what makes each species unique. It’s a useful method for advancing science and understanding the natural world.
