What makes the evolutionary lineage of platypus interesting?
What makes the evolutionary lineage of platypus interesting?
The truth about the platypus—and what makes the animal’s recent genomic sequencing particularly interesting—is that it belongs to a lineage that separated from ours approximately 166 million years ago, deep in the Mesozoic era, and since that time, it has independently lost different elements of our last common …
How has the platypus adapted to its environment?
Platypus is well adapted for semi-aquatic lifestyle. Its streamline body and a broad, flat tail are covered with dense waterproof fur, which provides excellent thermal insulation. The Platypus uses its tail for storage of fat reserves and the strong claws on its feet for burrowing and moving on land.
Which type of mammal evolved the earliest?
morganucodontids
The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time.
What type of evolution has resulted in the platypus’s unusual characteristics?
Warren led a 2010 study that found 83 toxins in platypus venom, which contains genes that resemble the venom genes of other animals, including snakes, starfish, and spiders. It’s likely an example of convergent evolution, in which unrelated species evolve similar traits.
What are three adaptations of a platypus?
It has several adaptations, or traits, that help it thrive, made for being in water, including webbed feet and a wide tail for swimming, extra fat stores in the tail, and a bill complete with electroreceptors for detecting prey’s electric currents under water.
What makes the platypus a unique and interesting mammal?
Platypus reproduction is nearly unique. It is one of only two mammals (the echidna is the other) that lay eggs. Females seal themselves inside one of the burrow’s chambers to lay their eggs. With the tail of a beaver, and a bill like a duck’s, the platypus is a real ungainly creature.

How does a platypus use its bill?
– Platypus use their bill to not only digest food and finding food, but also use it to navigate as they swim with their eyes closed. The bill has electoreceptors that detect electrical impulses that is generated by different species, this enables to indicate prey and predictors as well as the flow of water and other stationary objects.
Where do platypuses live in Australia?
Modern platypuses are endemic to eastern mainland Australia, Tasmania, and adjacent King Island, with a small introduced population on Kangaroo Island, South Australia, and are widely distributed in permanent river systems from tropical to alpine environments.
How does a platypus manage to survive in its environment?
– The Platypus’ kidney can dispose water much quicker then normal mammals, as it is exposed to a lot of freshwater and can absorb the salts more efficiently to compensate their freshwater environment. – The platypus uses its bill to dig in the sand to locate pray.
