Q & A
Why do chimps fling their feces and what does it indicate about their behavior?
-Chimps fling feces because they have fewer objects to throw in captivity, and they've learned that it gets a bigger reaction than other objects. It's not an act of immaturity; chimps with better aim have more developed motor and frontal cortices, indicating they are smarter and better communicators.
Which species of bee can die from stinging, and why does this happen?
-The honeybee is the species that can die from stinging. This occurs because their stinger is barbed and gets caught in mammal skin when they attempt to withdraw it, leading to the stinger being ripped out of the bee's abdomen.
Why do some people believe that the egg came before the chicken, and what does modern biology say about this?
-Some people believe the egg came first based on religious beliefs or ancient texts that mention a cosmic egg from which existence hatched. Modern biology suggests that eggs came first since reptiles laid eggs 300 million years ago, long before birds, and thus chicken eggs, existed.
How do pigs use mud to regulate their body temperature and protect themselves from the sun and parasites?
-Pigs, lacking in sweat glands, roll in mud to keep cool as the mud lowers their body temperature more effectively than water alone due to its slow evaporation rate. The dried mud also forms a protective barrier against the sun and keeps parasites from biting them.
Why do horses wear shoes and how do they differ from the hooves of wild horses?
-Horses wear shoes to protect their hooves from damage caused by carrying heavy loads or working on soft ground. Domestic horses' hooves are more prone to cracking or splitting due to their inconsistent movement and living conditions. Wild horses, on the other hand, move more evenly and live in dry, flat places, which naturally wear out their hooves evenly and keep them hard.
How do chameleons change their color and what is the primary reason for this ability?
-Chameleons change color primarily through special cells called iridophores in their skin, which act like microscopic prisms to reflect light in different ways. This color-changing ability is more about reflecting their emotions and signaling to other chameleons rather than camouflage.
Which animal is considered the deadliest on Earth and why?
-Mosquitoes are considered the deadliest animals on Earth because they can spread viruses like malaria, dengue, and Zika from person to person, leading to millions of deaths annually.
Do horses sleep standing up and why is this behavior beneficial for them?
-Yes, horses can sleep standing up due to special joints in their legs that allow them to lock their knees. This behavior is beneficial as it allows them to quickly escape from predators and also takes less energy than lying down.
Why do birds sing more loudly and frequently during the dawn chorus?
-Birds sing during the dawn chorus to attract a mate or warn other birds to stay away from their territory. The early morning is quieter, allowing their songs to travel further, and singing when they are heaviest proves their strength and fitness.
Why do sloths move so slowly and what impact does their diet have on their energy levels?
-Sloths move slowly due to their diet, which consists mainly of fruits, flowers, and leaves that are low in protein and fat, resulting in low energy levels. Their slow movement helps conserve energy, and they only need to descend to the ground to defecate once a week.
How do chimps at zoos or wildlife sanctuaries differ in their behavior from chimps in the wild?
-Chimps in zoos or wildlife sanctuaries, having fewer objects to throw, tend to throw feces more often. In contrast, chimps in the wild prefer to throw rocks and sticks when they are scared, annoyed, or anxious.
What is the significance of a honeybee's stinger being barbed and how does it affect the bee when it stings a mammal?
-A honeybee's barbed stinger is designed to dig deep into the skin, which is beneficial for injecting venom. However, when stinging mammals, the barbs can get caught in the thick skin, causing the stinger to be ripped out as the bee tries to fly away, often leading to the bee's death.
Outlines
🐒 Chimpanzee Poo-Flinging Explained
Chimps are known for throwing feces, which seems nonsensical but is actually a strategic behavior. Unlike in the wild, where chimps tend to throw rocks and sticks, those in captivity lack such items and resort to poop due to its abundance. This action elicits a strong reaction, which chimps learn over time. Interestingly, chimps with better aim at feces-throwing exhibit more developed motor cortices, indicating greater physical coordination, and more developed frontal cortices, which process language, suggesting they are smarter and better communicators. So, poo-flinging is a chimp's way of sending a warning.
🐝 The Truth About Bees and Their Stings
Among the many bee species, only the honeybee dies after stinging humans. This occurs because a honeybee's stinger, which is barbed, gets caught in human skin and is ripped out when the bee attempts to leave, leading to its death. This is not a deliberate act but a consequence of the bee's anatomy interacting with the thickness of mammal skin. Honeybees can sting other insects and most animals without this outcome. Despite the bee's death, it can continue to inject venom for up to 10 minutes unless the stinger is removed. Male honeybees lack stingers, and worker bees are the only ones capable of stinging.
🐔 The Chicken and the Egg: An Age-Old Question
The debate over which came first, the chicken or the egg, has cultural and scientific facets. Some medieval Europeans believed the chicken came first as they thought God created birds before eggs. Others believed in a cosmic egg from which existence hatched. Biologists argue that eggs came first, as reptiles laid eggs 300 million years ago, with birds appearing much later. According to NPR's Robert Krulwich, a mutated egg laid by non-chicken birds resulted in the first chicken, making the egg the precursor to the chicken species.
🐷 The Mud Baths of Pigs: A Cooling Mechanism
Pigs are often seen rolling in mud, which is more than just a playful habit. It serves as a cooling mechanism due to pigs having fewer and less effective sweat glands compared to humans. Mud helps lower their body temperature significantly more than sweating, as it takes longer to evaporate. This mud bath also offers protection against the sun, parasites, and insects. Contrary to their reputation, pigs are clean animals that avoid defecating near their sleeping or eating areas, and they use mud to keep cool and safe, as well as for enjoyment.
🐴 The Importance of Horseshoes for Domestic Horses
Horseshoes are essential for domestic horses due to their heavy weight and the various surfaces they traverse. Horses' hooves, made of keratin, require protection from wear and tear. Domestic horses, unlike their wild counterparts, are often on soft or uneven ground and carry significant loads, which makes their hooves more susceptible to damage. Wild horses, which live in dry, flat environments and move slowly, experience even wear on their hooves. Horseshoes have evolved into a standard to protect domestic horses' hooves from such damage.
🦎 Chameleons: The Mood-Color Changing Reptiles
Chameleons are known for their color-changing abilities, which are not primarily for camouflage despite their effectiveness in blending in. With over 160 species, not all chameleons can change color. Their color shifts are more about expressing emotions and signaling to others. Dark colors may indicate anger, while bright colors are used to attract mates. Chameleons also change colors based on temperature, becoming lighter to reflect heat or darker to absorb warmth. The color change is facilitated by iridophores, cells that act like microscopic prisms to reflect light and create a spectrum of colors.
🦟 Mosquitoes: The Deadliest Creatures on Earth
Despite the size and strength of animals like elephants and hippos, mosquitoes are considered the deadliest animals on Earth due to their ability to spread life-threatening diseases. Diseases such as malaria, dengue, and Zika are transmitted through mosquito bites, leading to millions of deaths annually. However, medical advancements have significantly reduced malaria deaths by almost 40% since 2000. Mosquitoes' impact on human health is substantial, and precautions like using bug spray are advised, especially in high-risk areas.
🐎 Horses Sleeping Standing Up: A Survival Mechanism
Wild horses often sleep standing up as a survival strategy to quickly escape from predators. Their straight backs make it harder to rise quickly from the ground, so sleeping on their feet allows them to be ready for flight. Horses have special leg joints that lock their knees, enabling them to sleep standing without falling over. However, they still need to lie down for deep, restful sleep. Horses in a group take turns to stand guard while the others sleep, rotating this role for adequate rest.
🐦 The Dawn Chorus: Birds' Morning Serenade
The dawn chorus, a period in the early morning where birds sing loudly and frequently, serves multiple purposes. Primarily, it's a way for birds to attract mates or warn others of their territory. The early morning, when birds are at their heaviest after a night's rest, is a time when they can demonstrate their strength and fitness through their singing. This show of vitality helps them appear more attractive to potential mates and deters other birds from encroaching on their territory.
🦥 Sloths: The Slow-Paced Life of the Tree-Dwelling Mammals
Sloths are slow-moving creatures due to their diet primarily consisting of fruits, flowers, and leaves, which are low in protein and fat that usually provide energy. This results in a need to conserve energy, leading to their characteristic slow movement and minimal activity. Their method of digestion is equally slow, taking up to a month to fully process a meal. This slow pace extends to their social habits, as they only descend to the forest floor to defecate once a week, which is a vulnerable time for them and results in a significant bowel movement, weighing up to one-third of the sloth's body weight.
