Toxicity is a good defense, until it isn't

5️⃣ Explain Like I'm 5

Imagine you're a toad that lives in South America, and you have a superpower — you're super toxic! If a bigger animal tries to snack on you, your body can make a scary poison that might make the animal very sick or even cause a heart attack. It's like having a built-in security system! But guess what? Some of the animals in your neighborhood have figured out how to deal with your poison. They've gotten super strong stomachs or special body tricks that let them eat you without getting sick. It's kind of like some superheroes who can walk through walls or stop time — they just have the right tools to get past your defenses!

Okay, so you're this toad in South America, and you have a secret weapon called a cardiotonic steroid. It's a type of poison that can make an animal's heart stop working right if they try to eat you. Pretty cool defense, right? But nature is always changing. Some of the animals that might want to eat you have evolved, which means they've slowly changed over many years to survive even with your poison. They've developed special ways to not get hurt by your toxins.

Shabnam Mohammadi, an evolutionary biologist, studies how these adaptations happen. She's looked at how some animals can just munch on toxic creatures like you without any problems. It turns out that humans have also known about these toxins since ancient times in Egypt and have used them for various purposes. So, while being toxic is a great way to protect yourself, it's not foolproof because nature is always playing this game of catch-up where everyone tries to outsmart everyone else.

In the complex ecosystem of South America, there's a toad that uses a potent toxin, specifically a cardiotonic steroid, as a defense mechanism. This toxin can severely affect the heart function of potential predators, essentially causing a heart attack if ingested. However, the plot thickens as some predators have evolved adaptations that allow them to tolerate or even ignore the effects of these toxins. This is a prime example of evolutionary arms race — where prey and predators continuously evolve new strategies to outcompete each other.

Evolutionary biologist Shabnam Mohammadi has dedicated her career to understanding these adaptations. Her research sheds light on how certain animals have developed physiological or behavioral traits that negate the effects of these toxins. Interestingly, this isn't just a modern-day scientific inquiry. Humans have known and utilized these toxins since the times of ancient Egypt for various purposes, showing a long history of biological awareness and exploitation.

This ongoing study not only helps us understand the dynamics of predator-prey interactions but also offers insights into how human beings have historically interacted with and used natural toxins for their benefit, whether for hunting, medicine, or other technologies. As we learn more about these evolutionary adaptations, it could lead to advancements in medicine, especially in how we understand and manage heart diseases and other toxin-related conditions.
