Study Traces Animal Vocal Abilities to 400-Million-Year Origins
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: Scientists have traced back the origins of vocal communication to over 400 million years ago, revealing it as an ancient shared trait among vertebrates rather than independently evolved abilities.
📈 One key stat: Research spanning 1,800 species across major vertebrate groups traced acoustic communication back to a common ancestor from 407 million years ago, fundamentally changing our understanding of how animals communicate.
💬 One key quote: “Many turtles, for example, which were thought to be mute, are in fact showing broad and complex acoustic repertoires,” says Gabriel Jorgewich-Cohen, a PhD student at the Paleontological Institute and Museum of UZH.“
1️⃣ The big picture: Scientists have made a remarkable discovery about the evolution of vocal communication in animals. New research from the University of Zurich reveals that the ability to produce and interpret sounds originated from a single common ancestor over 400 million years ago, rather than evolving separately in different species as previously thought. The study examined vocal recordings and behavioral data from 53 species across major vertebrate groups, including creatures previously assumed to be silent like turtles and lungfish. When combined with data from 1,800 species, the research showed that many supposedly mute animals actually have complex sound repertoires, fundamentally changing our understanding of how vertebrates communicate.
2️⃣ Why is this good news: This discovery opens up exciting new perspectives on animal communication and evolution. Understanding that vocal abilities stem from a shared ancient origin helps explain the widespread nature of acoustic communication across species today. The finding challenges previous assumptions about which animals can produce sounds, suggesting many more species may have undiscovered vocal abilities. This knowledge enables better understanding of animal behavior and communication, potentially leading to improved conservation efforts and deeper insights into the evolution of complex behaviors in all vertebrates.
3️⃣ What’s next: Scientists need to conduct more research on underrepresented species to uncover their potential vocal abilities. Studies can focus on documenting and analyzing sound repertoires of animals previously thought to be silent. The findings also create opportunities to investigate how these ancient communication systems evolved into the diverse vocal abilities seen in modern animals. Understanding these evolutionary pathways can provide insights into the development of communication in all vertebrates.
