brown bear

The world's most widely distributed bear species, brown bears range from North America and Europe across Russia to Japan, occupying forests, tundra, and alpine meadows. Adults can weigh up to 700 kg in coastal Alaskan populations. Omnivores that consume berries, roots, fish, and carrion, brown bears are a keystone species that distribute nutrients across landscapes. Most populations are stable, though some subspecies are threatened.

chimpanzee

Humanity's closest living relative, sharing approximately 98.7% of DNA, chimpanzees inhabit tropical forests and savanna woodlands across central and West Africa. Highly intelligent, social primates that use and make tools, display cultural traditions, and communicate with rich vocalizations including the distinctive pant-hoot. Endangered, with populations declining due to deforestation, bushmeat hunting, and disease transmission from humans.
