I didn’t know / gorillas use eye contact / to

keep good relationships. /

I always thought / they

were <span class='nw'>aggressive</span> animals. /

I get <span class='nw'>scared</span> / when they

<span class='nw'>beat</span>
their <span class='nw'>chests</span>. /

That <span class='nw'>gesture</span> is called / “chest

<span class='nw'>beating</span>.” /

When we see it, / we usually think / they

are very <span class='nw'>violent</span>. /

However, / it doesn’t always mean /

they are angry. /

Why do they beat their chests? /

They beat their chests / when they

want to catch others’ <span class='nw'>attention</span>, / show <span class='nw'>excitement</span>, /

or give <span class='nw'>warnings</span>. /

When young gorillas are

playing, / they often beat their chests / in turns. /

Human children shout / at each other / when they

play. /

These two <span class='nw'>behaviors</span> are similar. /

Gorillas

also beat their chests / when two groups of gorillas /

are <span class='nw'>approaching</span> / each other. /

When the two groups

meet, / trouble can happen. /

Each group <span class='nw'>warns</span> the

other / about coming closer. /
