what if the dinosaurs never went extinct? “If dinosaurs didn’t go extinct, mammals probably would’ve remained in the shadows, as they had been for over a hundred million years,” says Brusatte. “Humans, then, probably would’ve never been here.” But Dr. Gulick suggests the asteroid may have caused less of an extinction had it hit a different part of the planet.
What would happen if dinosaurs were still alive today? It’s likely that, with a preponderance of dinosaurs remaining on our planet, humans and many other mammals would not have had the chance to evolve into existence. “Even though mammals thrived in the shadow of the dinosaurs, they did so at small size,” writes Switek.
What killed the Aboriginal people? From the late 1840s, massacres were carried out as daylight attacks by native police, sometimes in joint operations with settlers.

what is the most common cause of extinction today?
Destruction of Habitat – It is currently the biggest cause of current extinctions. Deforestation has killed off more species than we can count. Whole ecosystems live in our forests. It is predicted that all our rainforest can disappear in the next 100 years if we cannot stop deforestation.
what caused the extinction of the megalodon sharkweek discovery channel?
“ There are several theories about what could cause a 50-foot long predatory fish to go extinct, including climate change (the ocean was much warmer then), extinction of prey species, and increasing competition for prey due to the evolution of cooperative hunting orca whales.
How long was the coelacanth thought to be extinct?
And maybe strangest of all, researchers think pregnancy in the fish lasts about five years. Coelacanths, which have been around for 400m years, were thought extinct until they were found alive in 1938 off South Africa. Scientists believed for a long time that coelacanths live about 20 years.
Are we cloning extinct animals?
CHEYENNE, Wyo. — Scientists have cloned the first U.S. endangered species, a black-footed ferret duplicated from the genes of an animal that died over 30 years ago. The slinky predator named Elizabeth Ann, born Dec.
How much higher is the rate of extinction now?
Modern extinction rates average around 100 E/MSY. This means birds, mammals and amphibians have been going extinct 100 to 1000 times faster than we would expect. Researchers think this might even be an underestimate. One reason is that some modern species are understudied.
Is it possible that Megalodons are still alive?
Megalodon is NOT alive today, it went extinct around 3.5 million years ago. Go to the Megalodon Shark Page to learn the real facts about the largest shark to ever live, including the actual research about it’s extinction.
What if Megalodons were alive today?
For starters, if megalodon sharks still roamed our oceans, the last place they’d be going would be the Mariana Trench! Megalodons were warm water mammals, so the frigid temperatures of the Mariana Trench would make it impossible for them to survive there.
How do you say in Japanese it is what it is?
Shouganai basically means ‘it is what it is’ or ‘it can’t be helped. ‘ It expresses acceptance of a bad situation or defeatism.

Is the Japanese word for no?

What would happen if the honey bee went extinct?
Without bees, the availability and diversity of fresh produce would decline substantially, and human nutrition would likely suffer. Crops that would not be cost-effective to hand- or robot-pollinate would likely be lost or persist only with the dedication of human hobbyists.
What animals went extinct in the Colosseum?
Thousands of bears, panthers, leopards, lions, and elephants were killed in the Colosseum—but how did they get there in the first place?
What caused the extinction of megalodon?
These studies suggested that shifting food-chain dynamics may have been the primary factor in megalodon’s demise, as the availability of its primary food source, baleen whales, decreased and the numbers of its competitors—smaller predatory sharks (such as the great white shark, Carcharodon carcharias) and whales (such …
What is an extinction burst and spontaneous recovery and how do they differ?
An extinction burst is a dramatic increase in the frequency/duration/intensity of the problem behavior. … Spontaneous recovery occurs after the behavior starts to go away and can happen even without reinforcement. You could be doing everything right and all of a sudden the behavior will pop back up.
How is extinction a threat to biodiversity?
The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.
What living things survived the Permian mass extinction?
Two groups of animals survived the Permian extinction: Therapsids, which were mammal-like reptiles, and the more reptilian archosaurs. In the early Triassic, it appeared that the therapsids would dominate the new era.
How do environmental changes increase the risks of extinction?
The complex network of interdependencies between plants and animals multiplies the species at risk of extinction due to environmental change, according to a new study. In the case of global warming, predictions that fail to take into account this cascading effect might underestimate extinctions by up to 10 times.
