how did megalodon went extinct?
We know that megalodon had become extinct by the end of the Pliocene (2.6 million years ago), when the planet entered a phase of global cooling. Precisely when the last megalodon died is not known, but new evidence suggests that it was at least 3.6 million years ago.
what is the background extinction rate today?
In nearly all comparisons of modern versus background extinction rates, the background rate has been assumed to be somewhere between 0.1 and 1 species extinction per 10,000 species per 100 years (equal to 0.1 to 1 species extinction per million species per year, a widely used metric known as E/MSY).
is leprosy extinct?
Leprosy is no longer something to fear. Today, the disease is rare. It’s also treatable. Most people lead a normal life during and after treatment.
Which bird went extinct?

What do we mean by extinct?
So, what is extinction? Extinction of a particular animal or plant species occurs when there are no more individuals of that species alive anywhere in the world – the species has died out. This is a natural part of evolution.
How did the extinction of dinosaurs help mammals?
With dinosaurs no longer eating them, mammals made quick evolutionary strides, assuming new forms and lifestyles and taking over ecological niches vacated by extinct competitors.
Will wasps become extinct?
But now scientists at University College London claim that we need to change our ideas to stop them dying out. Like bees, wasp numbers are in decline, with a reduction in numbers of 50% in 20 years – and wasps are actually key to pollination, just like bees.
How many swift fox are left?

Which groups were most affected by the Late Triassic extinction?
The end-Triassic extinction particularly affected the ammonoids and conodonts, two groups that serve as important index fossils for assigning relative ages to various strata in the Triassic System of rocks. Indeed, the conodonts and many Triassic ceratitid ammonoids became extinct.
What caused the near extinction of the bison?
Many people hunted these animals for their meat, but there were many industrial uses for their hides, hooves, and bones. Non-indigenous hunters practiced hunting in huge numbers. With such a demand in the market, the populations of bison decreased very quickly.
What year did sea cows become extinct?
By 1768, less than three decades after they were first described, the Steller’s sea cow was extinct.
Would it be good if mosquitoes went extinct?
This produces nutrients that are important for the plants. Without mosquitoes, plant growth could be affected. Wiping out mosquitoes would also wipe out a group of pollinators. Only some species feed on the blood of humans and animals, and even in those species, the females are the only ones sucking blood.
What is the main cause of extinction on Earth today?
The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
How do scientists know a mass extinction took place?
Scientists know when a mass extinction took place because they can date the rocks that a fossil is found in to determine its age.
Is leprosy curable now?
The disease mainly affects the skin, the peripheral nerves, mucosa of the upper respiratory tract, and the eyes. Leprosy is curable and treatment in the early stages can prevent disability. Leprosy is an age-old disease, described in the literature of ancient civilizations.
What happened sea cow?
sea cow, (Hydrodamalis gigas), also called Steller’s sea cow, very large aquatic mammal, now extinct, that once inhabited nearshore areas of the Komandor Islands in the Bering Sea.

How did Iguanodon go extinct?
Iguanodons were ornithopod dinosaurs that followed a plant-based diet and were present on Earth during the Late Jurassic to Early cretaceous period around 126-122 million years ago. According to paleontology, after that time, their number decreased and eventually their population was wiped out.
What would happen if all the elephants died?
