Closing the gap

Article Abstract:

Scientists have recently discovered that chimpanzee communities have cultural diversity, leading some to believe that they practice learned cultural behaviour. All chimpanzee communities are similar in their social order, but many groups have food-gathering practices and mating rituals that are exclusive to that group. Some believe this is a result of genetic specialization due to environmental differences between groups, while others are willing to claim that chimps are learning in the same way early humans did.

The myth of monogamy

Article Abstract:

Research reveals that many animals assumed to be monogamous do not mate exclusively with a single partner. Although they may form long-lasting social relationships, these are established separately from biological pairings. Primates and bird species are among the most notable for extra-pair mating behavior. Evolutionary explanations include the need for males to widen the gene pool, and the need for females to ensure their fertility.

Stick out your tongue

Article Abstract:

Some species of animals have tongues that help them get their food. Giraffes use their long tongues to gather leaves from the tops of trees, while the pangolin sticks its tongue deep into anthills to capture its meals. The tongues of vampire bats are specially shaped to ingest its diet of blood. Hummingbirds' tongues are like tubes, allowing nectar to be drawn up through them.
