Birds, frogs, and reptiles use sound to “program” embryos…It affects how a variety of species prepare for life outside the womb or egg.

Anew study suggests that sound plays a much larger role in animal development than previously thought, affecting how a variety of species prepare for life outside the womb or egg.
“(W)hat is most striking from the evidence we’ve gathered is how common it is for embryos across species to rely on sound information,” researcher Mylene Mariette of Deakin University said in a press release.
How it works: Some animals listen and react to the world outside while they’re still just embryos, taking cues from both their parents and their environments that guide their development.
The phenomenon is called “acoustic developmental programming,” and while the developing animals don’t consciously know that they’re receiving these instructions, that doesn’t stop their bodies from responding to the sounds.
“This is because sound directly impacts behavior and physiology, without any conscious processing,” Mariette said.
What’s new: While researchers had seen examples of acoustic developmental programming before, this was the first study to document just how prevalent it is amongst animals.
Zebra finch parents, for example, have a high-pitched noise they make while incubating their eggs if it’s very hot out. Baby birds whose parents make those noises, the researchers say, respond by growing slower — a trait that helps them survive in higher temperatures once they’re born.

When crickets are nymphs (the stage between egg and adult), females will develop faster if they hear males’ reproductive “songs” — that’s so they can take advantage of the opportunity to mate.
Male nymphs, meanwhile, hear those songs and interpret them as more sexual competition — in response, they slow down development and invest more resources into reproduction.
Sound matters: Now that we know that acoustic developmental programming is common across species, it could change how we study animal development, particularly in terms of nature vs. nurture.
“If this result is really consistent, I think this may have a very big impact on how we think about what is innate behavior and what is learned behavior,” Wang-chun Liu, a Colgate University neuroscientist, who wasn’t involved with the study, told Popular Science.

THIS SUBJECT is very concerning to me here in the Arkansas Ozarks where a lawless utility CORPORATION has FORCED a very toxic form of electric meter on it’s “members”. It’s known as a TWACS (Two Way Automated Communication System) which carries data over electric lines only designed to carry current. This has apparently produced a 24/7 squeal here. They do so while calling themselves a “member owned cooperative” but also reportedly locking said members out of public meetings and changing rules to control who gets on the board, according to reports of several locals. How can you be a “member-owned cooperative” and not allow said members to vote on something this important?
This meter system was rejected at the federal level by the Austrian Chamber of Physicians and the Swiss Physician’s for the Environment because of concerns that it’s DEADLY. It’s been rejected at the federal level by The Austrian Chamber of Physicians (like our AMA) and the Swiss Physicians for the Environment who were “so alarmed about widespread health effects from PLC that they opposed itat the federal level…Effects can be immediate as well as cumulative. Reports from states that have this indicate this is potentially deadly, with the most vulnerable feeling the effects soonest”?
This is a very dense eco system here andto have it SCREAMING 24/7 with a high-pitched squeal that locals say began immediately upon install of this TWACS metering system seems destructive to the wildlife and this article helps shore up that strong sense of this.
