It is pointed out in the passage that observing animals ----.

The skill of observing animals to aid our survival dates
back millennia. Nearly 6,000 years ago, indigenous
people of North America used their deep understanding
of bison behaviour to devise an efficient way to hunt. In
modern times, our interest in animal behaviour comes
with new insights and terminology. ‘Herd sourcing’, for
example, borrows from the word: ‘crowdsourcing’, but
centres on using the collective intelligence of wildlife
rather than people. Over the last few years, watching
animals for the clues they provide about the natural
world has shifted from folklore to science. In 2013, for
example, US scientists put to the test the ‘old wives’
tale’ that cows lie down when rain is on its way. The
researchers measured the core body temperature of
cattle and found that cows lie down when it is cold and
stand up when it is hot to disperse heat. While it may
not accurately predict precipitation, it does show a link
between cattle behaviour and the weather.
