The surprising evolution of the weirdest animals on Earth according to a new study систематизировать материал The story of two of the strangest animals on the planet just got a little stranger thanks to clues revealed by a lone fossil specimen that scientists now say represents a long-extinct ancestor. The new research could upend what’s known of the evolution of the most primitive mammals alive today. Found in Australia and New Guinea the platypus and echidna are called monotremes and they are unique for being the only mammals that lay eggs. The amphibious platypus has a bill and webbed feet like a duck and a beaver-esque tail. The small creature spends much of its time hunting for food in the water. The echidna — fittingly known as the spiny anteater — lives entirely on land is covered in pointy quills and has rear feet that face backward kicking up dirt as the animal burrows into the ground. Neither animal has teeth and though they both produce milk they secrete it through their skin for babies often called puggles to lap at because they lack nipples. “There’s plenty of weirdness to go around on these little things” said Dr. Guillermo W. Rougier a professor in the department of anatomical sciences and neurobiology at Kentucky’s University of Louisville who studies early mammalian evolution. “They are one of the defining groups of mammals” Rougier said. “The typical mammal from the time of dinosaurs probably shared a lot more biology with a monotreme than with a horse a dog a cat or ourselves.” Therefore he said monotremes provide a window into the origins of mammals on Earth.
Axolotl problems As Mexico City grew and became more industrialized the need for water brought pumps and pipes to the lake and eventually “it was like a bad smelly pond with rotten water” Zambrano said. “All of our aquatic animals suffer with bad water quality but amphibians suffer more because they have to breathe with the skin.” lucky jet играть To add to the axolotls’ problems invasive fish species such as carp and tilapia were introduced to the lake where they feed on axolotl eggs. And a 1985 earthquake in Mexico City displaced thousands of people who found new homes in the area around the lake further contributing to the destruction of the axolotls’ habitat. These combined threats have devastated axolotl populations. According to the International Union for Conservation of Nature there are fewer than 100 adult axolotls left in the wild. The species is considered critically endangered. https://lucky-jetts.com lucky jet игра While the wild axolotls of Lake Xochimilco have dwindled to near-extinction countless axolotls have been bred for scientific laboratories and the pet trade. “The axolotl essentially helped establish the field of experimental zoology” Voss said. In 1864 a French army officer brought live axolotls back to Europe where scientists were surprised to learn that the seemingly juvenile aquatic salamanders were capable of reproduction. Since then scientists around the world have studied axolotls and their DNA to learn about the salamanders’ unusual metamorphosis or lack thereof as well as their ability to regrow injured body parts. In addition to their role in labs axolotls have become popular in the exotic pet trade though they are illegal to own in California Maine New Jersey and Washington DC. However the axolotls you might find at a pet shop are different from their wild relatives in Lake Xochimilco. Most wild axolotls are a dark grayish brown. The famous pink axolotls as well as other color variants such as white blue yellow and black are genetic anomalies that are rare in the wild but selectively bred for in the pet trade. What’s more “most of the animals in the pet trade have a very small genetic variance” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. Plus the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.

Why axolotls seem to be everywhere — except in the one lake they call home kraken даркнет Scientist Dr. Randal Voss gets the occasional reminder that he’s working with a kind of superstar. When he does outreach events with his laboratory he encounters people who are keen to meet his research subjects: aquatic salamanders called axolotls. The amphibians’ fans tell Voss that they know the animals from the internet or from caricatures or stuffed animals exclaiming “‘They’re so adorable we love them’” said Voss a professor of neuroscience at the University of Kentucky College of Medicine. “People are drawn to them.” https://kra31f.cc кракен вход Take one look at an axolotl and it’s easy to see why it’s so popular. With their wide eyes upturned mouths and pastel pink coloring axolotls look cheerful and vaguely Muppet-like. They’ve skyrocketed in pop culture fame in part thanks to the addition of axolotls to the video game Minecraft in 2021. These unusual salamanders are now found everywhere from Girl Scout patches to hot water bottles. But there’s more to axolotls than meets the eye: Their story is one of scientific discovery exploitation of the natural world and the work to rebuild humans’ connection with nature. A scientific mystery Axolotl is a word from Nahuatl the Indigenous Mexican language spoken by the Aztecs and an estimated 1.5 million people today. The animals are named for the Aztec god Xolotl who was said to transform into a salamander. The original Nahuatl pronunciation is “AH-show-LOAT”; in English “ACK-suh-LAHT-uhl” is commonly used. Axolotls are members of a class of animals called amphibians which also includes frogs. Amphibians lay their jelly-like eggs in water and the eggs hatch into water-dwelling larval states. In frogs these larvae are called tadpoles. Most amphibians once they reach adulthood are able to move to land. Since they breathe in part by absorbing oxygen through their moist skin they tend to stay near water. Axolotls however never complete the metamorphosis to a land-dwelling adult form and spend their whole lives in the water. “They maintain their juvenile look throughout the course of their life” Voss said. “They’re teenagers at least in appearance until they die.”

What’s more “most of the animals in the pet trade have a very small genetic variance” Zambrano said. Pet axolotls tend to be inbred and lack the wide flow of different genes that makes up a healthy population in the wild. That means that the axolotl extinction crisis can’t simply be solved by dumping pet axolotls into Lake Xochimilco. Plus the pet axolotls likely wouldn’t fare well with the poor habitat conditions in the lake.
