Evolution's Surprising Candidates: Who Might Rise as Earth's New Dominant Species?

Exploring the Unconventional Intelligence and Remarkable Adaptations of Earth's Lesser-Known Creatures

By B.BallentynePublished 3 months ago 6 min read

In the absence of Homo sapiens, which creatures might step up to become the new dominant species? Scientists have some intriguing ideas, thanks to modern gene sequencing technology and our evolving understanding of evolution.

We know that our planet's climate will continue to change, forcing many species to adapt to survive. Convergence, a phenomenon where unrelated organisms develop similar traits to thrive in a specific environment or niche, will also play a pivotal role. Take, for instance, the fish – perfectly designed for aquatic life with their torpedo-like bodies and fins. Yet, consider the dolphin, a warm-blooded, air-breathing mammal with an entirely different evolutionary background. Despite these differences, dolphins have evolved similar body shapes to fish. Could other animals develop dexterous hands akin to ours for activities like city-building and modifying the environment?

Enter primates, like chimpanzees and bonobos, which are already quite adept with their opposable thumbs, using them to fashion tools in the wild. These creatures could be primed to step into the role of architects of the animal world.

However, don't discount birds – the last surviving descendants of dinosaurs. Birds display remarkable intelligence and can form large social groups, with some species, such as sociable weavers, even constructing communal nesting sites. While their cities might not look like human metropolises, they possess an unexpected aptitude for complex social structures.

And let's not overlook octopuses, arguably the smartest non-human animals on Earth. They exhibit the ability to distinguish between real and virtual objects, showcasing their capacity for engineering their environment. Adapting to terrestrial life might pose a challenge, though, given their aquatic adaptations.

It's essential to recognize that our understanding of animal intelligence has evolved significantly over time. Historically, humans have often positioned themselves at the top of an intelligence hierarchy, relegating insects to the lowest rung. However, in the 1960s, a new generation of researchers challenged this notion, emphasizing the need to assess intelligence in relative terms. With technological advances, we can now observe animals in their natural habitats for extended periods without disturbing them, revealing surprising levels of intelligence.

For example, researchers in Melbourne use remote-controlled drones to study the breeding patterns of Southern right whales, while artificial intelligence aids in tracking and predicting the movements of various creatures. Interestingly, we tend to recognize intelligence in animals when their behaviour mirrors our own. Dolphins, for instance, use names and develop accents, with researchers identifying distinct accents among dolphins in southern Brazil after centuries of interaction with local fishers.

But it's not just mammals that display intelligence. Birds and insects also exhibit remarkable cognitive abilities. Parrots, known for their complex social groups, can differentiate between members of their species based on their relationships with one another. Even insects, with their minuscule brains, can perform impressive feats, such as tool use and observational learning.

Our understanding of intelligence has shifted from being a uniquely human trait to a distributed phenomenon across the animal kingdom. Different species excel in various domains, adapting to environmental pressures in their unique ways. While we often think of the usual suspects in the intelligence hierarchy – chimpanzees, dogs, dolphins, and more – there are some unexpected additions. You might even have one of these surprises napping in your lap right now: house cats. These feline friends are renowned for their ability to learn through observation and repetition. Some cats, like Nora, have taken it to the next level, showcasing their aptitude for piano playing – a testament to their adaptability and intelligence.

Now, let's delve into some remarkable animals that may not initially strike you as brilliant but possess unique qualities that defy expectations.

First, consider rats. Often dismissed as pests, some rats are aiding in life-saving endeavours in Africa. These furry detectives are trained to sniff out lung disease in saliva samples with incredible accuracy. Thanks to their keen sense of smell and quick learning abilities, they can detect specific bacteria in just seven minutes, a task that would take human scientists an entire day.

Nelly the Pig

Next up, Nelly the pig, a shining example of animal intelligence. Nelly tackled a series of challenges, including putting differently shaped objects through a hoop. She not only completed the task but also displayed problem-solving skills by comparing object shapes to the hoop. This highlights the intriguing spatial awareness and cognitive abilities of pigs, demonstrating that their intelligence extends beyond mere tricks.

Now, let's venture underwater. Imagine scuba diving among vibrant corals and colorful fish when suddenly, a massive shadow looms above. Fear not, for it's just a basking shark, a gentle giant of the seas. Basking sharks, although massive, pose no threat to humans, as they are filter feeders with no teeth. They cruise the ocean with mouths agape, swallowing plankton without harm to anyone.

Transitioning to the Central American jungle at night, you might hear the flapping of wings and fear the worst. But relax, it's likely just a wrinkle-faced bat, an entirely harmless creature with a unique appearance. These fruit bats use their wrinkled faces to collect fruit pieces and juice, allowing them to enjoy a tasty meal in peace.

In the Nepali National Park, you may encounter a creature that appears straight out of your nightmares – a crocodile. However, it's not as menacing as it seems. This crocodile is an Indian gharial, a species with a long, narrow snout ideal for catching fish. Gharials are primarily fish-eaters and pose no threat to humans.

In your own backyard, while digging in the soil, you might stumble upon a creature that resembles an alien invader. Fear not; it's just a star-nosed mole, sporting a distinctive star-shaped snout with tentacle-like appendages. These moles use their unique snouts to navigate and locate food, demonstrating their extraordinary adaptation to their underground habitat.

Back in the ocean, you might find yourself face to face with a toothy predator. However, this sand tiger shark is no cause for alarm. Despite its fearsome appearance, the sand tiger shark is a fish-eating species and poses no danger to humans. Its rows of sharp teeth are reserved for capturing prey like fish, not for attacking larger animals.

Finally, let's journey to the Australian outback. As you dig in search of water, you might unearth a thorny devil, a lizard covered in menacing thorns. While its appearance is intimidating, these thorns serve as protection against predators. If you avoid touching them, you'll find that thorny devils are harmless creatures.

Now, imagine finding yourself face to face with a tailless whip scorpion, a creature that might send shivers down your spine. These arachnids, found in various regions, are actually more afraid of you than you are of them. They lack stingers and typically avoid confrontation, making them relatively harmless to humans.

And don't be alarmed if you stumble upon a burrow inhabited by a hairless, big-toothed creature. It's likely a naked mole rat, an underground-dwelling rodent with remarkable adaptations. Despite their unusual appearance, naked mole rats are well-suited to their subterranean lifestyle, displaying unique qualities such as insensitivity to pain.

In the vast tapestry of the natural world, we encounter numerous creatures with peculiar

characteristics and surprising adaptations. These remarkable animals remind us that intelligence and survival take many forms, challenging our preconceived notions about the animal kingdom.

So, the next time you come across a creature that appears strange or intimidating, take a moment to appreciate the fascinating adaptations that make them unique. Nature's diversity is a testament to the wondrous complexities of life on Earth.
