Yes.There is no reason to think any other animal even understands the concepts involved, much less puts its own resources into trying to prevent the extinction of another species.An individual animal may on rare occasions delibetately take action to protect an individual of a different species, but that is not the same thing.As for the idea
There have been several human-like species that have existed on earth for the last 2 million years and all of them are extinct. But there have been only four human species including Homo sapiens, and three of them are extinct. The three extinct species are Homo
Can species that become extinct be replaced?Not in the way you might be angling at, in our current state of knowledge. We are not ready to clone extinct animals or plants from DNA present in fossil remains. Maybe one day.But if
In general, no. It isn't energy efficient for a predator to concentrate on hunting one prey species to extinction; as the number of prey declines, the predator would have to spend all its time searching for prey and this would be a prohibitive cost. Instead, the
Yes - absolutely, all the time.Species is a very lose term, and any animal can fairly quickly split and find any number of different niche survival strategies that in a relatively short time would cause us to consider it many multiple species.The vast majority of those diverging species will always die out - and they'll do
In the event of human extinction the likelihood of another species taking over is a long shot. Anything that might have looked remotely like competition was wiped out millennia ago.Depending on the size & scale of the destruction & depredation that caused the
The predictions I've been reading over the past five years all seem to point toward 2026 as the point there won't be livable habitat for humans (and by extension most other species). The fact that the Proceedings of the National Academy of Science just published a paper (which underwent editorial review)
Megafauna Extinction: Is there a modern example of primitive people hunting to extinction huge animals?
I find it difficult to believe that primitive humans, armed with spears with flint points maybe even bows and arrows, were able to wipe out or even have a significant impact on mega fauna.Especially, in areas like North American and Europe where natural predators were plentiful. On some isolated
Yes and no. For one, birds are dinosaurs*. So, at least one lineage of dinosaurs did survive. However, I'm assuming you mean the non-bird dinosaurs, aka the non-avian dinosaurs, and those all did go extinct a long time ago.Around 65 million years ago, there was the Cretaceous–Paleogene, K-Pg,
No way, Velociraptors were not even as fast as Troodon. Don't let the
Homo sapiens.Very smart but very stupid too.
We are still in the dark to accurately answer this question. However, estimates shall suffice for the time being.The reason? Scientists can't agree whether the major extinction events the Earth witnessed occurred over thousands or millions of years or simply in one lively day.
It's always very difficult to say for sure why a species went extinct, especially since many factors may be involved. But here's what studies have told us about C. megalodon.Fossils clearly indicate the extinction of C. megalodon by around 2.6 million years ago (no matter what the fake Discovery documentaries
When there are no more animals of a particular species left alive, that species is said to be extinct. In the distant past, several species of animals became extinct through natural causes. There might have been a change in the climate of a particular region, and the plants or animals on
Reptiles are animals. Mammals are animals, birds are animals, reptiles are animals. Reptiles are not plant life, nor are they bacteria, fungi, or viruses.Life is categorized into 8 taxonomic classifications: Domain, Kingdom, Phylum, Class, Order, Family, Genus and Species. The broadest
