Wild elephants in nature may use plants to heal themselves when they are sick. Scientists talked to local people and wildlife scouts who watch the animals. The local people said that elephants select special plants when they feel unwell.

heal themselves= ゾウが自分自身の体調や病気を治療するという再帰表現。

In one example, a wildlife scout saw elephant mothers prepare a plant to treat stomach pain. The mothers chewed the plant leaves and roots until they were smooth. Then, they mixed the plant material with their milk and gave it to their babies to chew.

until they were smooth= 噛む動作を植物が柔らかく滑らかな状態になるまで続けることを表す表現。

Researchers learned that elephants may use 35 different types of plants. Local people already use 25 of these same plants as natural medicines. Scientists believe that studying these plants could help people discover new medicines.

More evidence is needed to prove that elephant mothers intentionally give medical treatment to their calves. Scientists have given cameras to local wildlife experts to record the elephants' behavior. They hope to learn more about how animals care for their health in the wild.

More evidence is needed= 現在の観察結果から結論を出すにはさらなる証拠が必要であることを示す受動態表現。
