is humanity going to go extinct in 30 years? According to a 2020 study published in Scientific Reports, if deforestation and resource consumption continue at current rates, they could culminate in a “catastrophic collapse in human population” and possibly “an irreversible collapse of our civilization” in the next 20 to 40 years.
How many years does the earth have left? This is expected to occur between 1.5 and 4.5 billion years from now. A high obliquity would probably result in dramatic changes in the climate and may destroy the planet’s habitability.
Is extinction a natural part of evolution? The extinction of species (and larger groups) is closely tied to the process of natural selection and is thus a major component of progressive evolution. In some passages of the Origin, Darwin seems to have seen extinction as part of natural selection; in others, as an inevitable outcome.
Is extinction caused by humans? Human activity has been the main cause of mammalian extinctions since the Late Pleistocene. A 2018 study published in PNAS found that since the dawn of human civilization, 83% of wild mammals, 80% of marine mammals, 50% of plants and 15% of fish have vanished.

Save The Parasites? Scientists Warn They’re Endangered Too Scientists say parasites are important parts of ecosystems, but many are at risk of extinction. So, they’re calling for a parasite conservation movement.
What is offspring distribution?

How do nematodes survive?
Nematodes have developed a number of means by which they can survive desiccation, which include survival stages such as eggs, cysts, and dauer larvae ( Womersley et al.
How does the ProtParam tool work?
ProtParam computes various physico-chemical properties that can be deduced from a protein sequence. No additional information is required about the protein under consideration. The protein can either be specified as a Swiss-Prot/TrEMBL accession number or ID, or in form of a raw sequence.
How can we help penguins from climate change?
Marine reserves: The creation of large-scale, fully protected marine reserves can serve to alleviate pressure on penguins in the face of climate change, overfishing, and habitat degradation. Although marine reserves do not stop climate change, they can help keep ecosystems resilient and food webs intact.
Is there a dinosaur bigger than Argentinosaurus?
The discovery of such a large femur allowed many paleontologists to assert that Paralititan rivaled Argentinosaurus in size. Estimates of the titanosaur’s length and weight vary: length estimates range from 25 to 30.5 meters (82 to 100 feet), and weight estimates range from 60 to 75 metric tons (about 66 to 83 tons).

Why is it important to save cheetahs from extinction?
As predators, cheetahs control the number of prey species in their ecosystem. Cheetahs’ main prey are herbivores. Without cheetahs, these populations grow.
Why do endemic species face greater danger of extinction?
Endemic organisms are restricted only to a particular geographical area. They aren’t adapted to live in any other habitat. A change in their environment may cause their death. That is why endemic organisms are in greater danger of becoming extinct.

The last of the non-avian dinosaurs died out over 63 million years before the Pleistocene, the time during which the regular stars of the Ice Age films (mammoths, giant sloths, and sabercats) lived.

What was around 65 million years ago?
To explain what caused this mass extinction, scientists have focused on events that would have altered our planet’s climate in dramatic, powerful ways. The leading theory is that a huge asteroid or comet slammed into Earth 65 million years ago, blocking sunlight, changing the climate and setting off global wildfires.
