Global warming is an issue that society does not ignore; yet, its consequences are becoming more apparent every day, and it affects more than just humans.
Because of the climatic factors that surround us today, the planet’s flora and fauna are undergoing rapid changes. Different species fight to live as best they can in the face of habitat destruction, and scientists have just uncovered a peculiar hybrid bear.
Animals’ survival instincts drive them to escape their devastated habitats, and polar bears are one of the mammals compelled to migrate.
We’ve previously observed bears of this species famished and suffering in hot temps on their own land owing to a lack of food. However, they are now escaping the mayhem.
These bears have invented a new species in their desperate attempt to survive: the pizzly. A cross between polar bears and brown bears produced some unusual creatures. The former have almost completely lost their environment, but their mating cycle continues, and given the progressive extinction of their species, they have found a refuge in the browns.
Polar bears have been on the IUCN red list for years, but they have recently evolved into an unique crossbreed. The hue of the pizzly’s coat is a little perplexing, with a white coating atop brown hair extensions, similar to grizzly bears.
The substantial fat component of the arctic diet has vanished, as seen by bears’ appetite for seals, which are now nearly extinct. The polar bears have joined the browns in migrating and reproducing due to the melting of sea ice and their difficulty adjusting to the warming of the Arctic.
“This new species of bear is more climate change resistant and more suited to higher temperatures,” said DeSantis, a Vanderbilt University assistant professor.
Pizzly bears are said to have originated in Alaska, where many polar bears move to escape the arctic’s warming. This new species also contains several genes that, while they may appear to be novel, have already existed in the past.
“The polar bear and brown bear shared a similar ancestor 500,000 to 600,000 years ago,” the paleontologist claimed, “but they later split.”
When resources are few, these new bears would be accustomed to consuming hard things like plant roots or burrowing through carcasses. Polar bears do not have this ability.
