A new study involving INTRIGA monkey scientists

We know that even with years of study, many aspects of human evolution remain a great mystery. However, some monkeys are species Macaque footnotelocated in Phang Nga National Park, could be a key piece for studies on humans.

This is because mammals use stones to crack the outside of the fruit’s rinds, with the aim of opening them open and eating the nutritious interior. Therefore, the way primates do this is very similar to what human ancestors used.

For example, as a result of stones rubbing against fruits, the stone ends up crumbling. Scientists who analyze this type of behavior claim that it takes on a similar shape to ancestral tools found at archaeological sites.

The similarities can tell us something

What is most striking to researchers is that monkeys reproduce by mistake. For those involved in the research, this could be a great archaeological record of what has been reproduced by humans. That is, it is entirely possible that there is a connection between animals and human ancestors.

Lydia Luncz, one of the authors of the paper, says that this action by humans may be a possible precursor to intentional production. paying off:

Cracking nuts with stone hammers and anvils, similar to what some primates do today, has been suggested as a possible precursor to the deliberate production of stone tools.

This discovery shows how living primates can help researchers study the origin and evolution of tool use in our lineage.”

Therefore, it is very likely that our ancestors saw this act of animals at that time and reproduced it. And since it succeeded, it is possible that from that the work of hammers and anvils with stones was started.

The study is very important for us to find more evidence and try to better understand the ancestors of humans.
