Not only newly discovered animal species, but also hybrid animals such as the liger = lion+tiger.
These hybrid animals could then shape a new era.

Loading...Hallo zusammen, vorab, ich weiß dass Fliegenpilze ,,giftig“ sind. ich war gestern in mehreren Wäldern, rund um Magdeburg herum, und habe nicht einen einzigen Fliegenpilz gefunden. Wieso ist das so? Zur Zeit ist ja die Saison dafür…
Ich war beeindruckt. Nun möchte ich auch Utah und New Mexico in der Region sehen. Nachdem ich in Cali, Nevada, Arizona war. Oder auch zumindest mehr von Kalifornien sehen. Was meinst du? Magst du Kalifornien? Und was magst du oder magst du nicht an diesem Bundesstaat in den USA 🇺🇸❓
Hello, I found a terrarium and would like to know FROM A PROFESSIONAL, please, which animal I can put in it (non-toxic). Whether it's a snake or a scorpion, it doesn't matter! But no hamster or any other animal that needs hay because I'm allergic! Thanks. Terrarium size is: 30 high, 25 long, and 50…
hay I have to give a presentation about tigers and I need information where they live, how big and old they get, if they are solitary animals……etc. Many thanks in advance mfg Nicoo
I have now found and recorded such a toad
We bought a budgie, which we've had for two weeks now. But she's still somewhat shy. She's allowed to lie around in the room almost all day. She lets us pet her sometimes, in her cage, and sometimes in the entire room. She's been eating sunflower seeds from our hand since yesterday, but she doesn't…
Hybrid animals will be there again and again.
But in order to establish a new way, they must also be fertile.
This is very rare again, so the probability of the emergence of new species is very low.
If this happens, however, large jumps can be associated with the change of the phenotype, because whole groups, indeed systems of well-tested genes, are exchanged at once.
And it should necessarily be expected to have a higher diversity in the subsequent generations of the (new) species.
In addition, we are approaching the collapse of nature more and more quickly.

No, because these hybrids are usually sterile, they cannot reproduce. New species are not produced by mixing/hybridization, but by splitting off subspecies that specialize in certain new habitats or food sources. This is particularly fast at the crayons in Lake Victoria, which can develop new subspecies in the extremely short period of only 50 years, which no longer mate with other crayons. Buntbarsche show evolution in timelapse – Hamburger Abendblatt
Another interesting thing: in Africa, lions have been observed that specialize in fishing because they could not compete with the other ruddles as too small. If these lions could continue to grow and survive, their distant descendants could develop into a kind of giant otter, as they have already existed in the past, which then perhaps even go back to the seas over millions of years and develop into a new kind of whales. Also the ancestors of today’s whales were four-legged predators! Evolution runs over a long period of time in the same ways, the same living conditions lead to quite similar manifestations. Such parallel developments are called “convergence”.
Yes. Due to climate change, many animals flee to other areas of the earth and pair with other species such as the brown bear and the polar bear. Will give massive new animals through such incidents
The polar bear is in truth a subspecies of the brown bear. If it is to die out today through climate change, the surviving genetic material in the brown bear stocks (provided that the survival) can again produce polar bears in any distant future, as well as all living large cat species also possess the currently sleeping genetic material for saber teeth as with the extinct saber tooth tar.
Bär doesn’t care where.
Although not such because zb male ligers are always infertile also with females it only rarely applies to mules or mules.
In the course of evolution, new species develop over longer periods of time. It also dies species..Through humans it is currently a strongly accelerated extinction wave
Yeah, it will. Whether we are still experiencing this is questionable. New animal species do not necessarily arise from hybrids, since these are often sterile, i.e. not reproductive, depending on the intersection. This would be an evolutionary one-way road and will not prevail. Especially since it can happen that even if two species are similar enough to couple themselves, it can also be that they are still too far away genetically to testify to young people.
In the example of Liger, the parent animals are already inhabited on different continents, have different ways of living AND would occur in free wildlife as competitors. So, for example, lion’s ruddle makes tigers flat. This works only and exclusively in captivity, especially when artificial fertilization comes into play. There are still genetic problems. In Liger it is so that a hormone that does not stop growth in these animals, which leads to the giant growth of these hybrids and makes them unsuitable for the free wild. The reason for this is that this hormone is differently coupled with tiger and lion and is therefore not compatible with that of the partner animal, which makes it completely switched off.
But the species we know today will adapt to changing environmental conditions and change accordingly. There is also a BBC-Doku (I mean, at least, that it was the BBC…) “The future will be wild”. It speculates how today’s animal species up to 1 million. could develop and change years.
It will surely extinct many species or disappear in its present form, but that is nothing new and will blossom us, the people, even one day.
As long as the human being continues to spread, as long as industrialization progresses faster and more and more countries are entering, there will be no further animal species. It’ll always go in the other direction. There will be less and less species.
And not such a placative hybrid, but in the context of normal evolution (i.e. more in the division of existing species than in the intersection of such)…
… it’s just…
I’m sure it will happen in a few decades that a mammoth is born.
Scientists have been looking for an intact cell for over 10 years to plant it in the egg of an Asian elephant.
Since this is naturally (almost) impossible to find a truly intact cell, there is still a plan B.
Chief biologist George Chiarts in the USA has a plan B. He found out how to complete the plan. You need a living Asian elephant for this plan. The egg is changed in the elephant-gray SO, which all features arise from a wool hair mammoth.
Features Mammut: SHER thick fur, long and powerful fangs, small ears.
At least these features must appear so that the genetic manipulated elephant can survive in the cold and dry tundra.
Certainly, this is the course of evolution – it only takes place in periods that have nothing to do with human life expectations.
Researchers discover new animals every day, which they did not know yet.
Crossings or evolution will never stop.
So I don’t think so.
Industrialization will literally destroy nature.
she won’t.
It will destroy people and many mammals. But Earth/nature recovers over a few million years and we humans were just a whisper.
Yes, but no crosses
I’m sorry, but there are already crosses.

They have been artificially created under zoo conditions, such blends practically never happen in the wild, in India e.g. B. there are both wild lions and wild tigers, but do they mix?
