The duck, venturing down the creek far from her tribe, was abducted by Biggoon, a large water-rat who took the duck as his wife. The duck eventually escaped and returned to her tribe, where she laid two eggs which hatched as platypuses.
When did platypuses evolve?
about 166 million years ago
The monotremes diverged from other mammals about 166 million years ago and today the platypus is one of the most evolutionarily distinct animals on Earth.
Did dinosaurs evolve platypus?
Just about everyone loves the platypus, but for years the strange little monotreme has keep its secrets to itself. Now Australian scientists have discovered that the platypus is significantly older than previously thought: it may have been around since 120 million years ago, meaning it lived alongside the dinosaurs.
What is special about a platypus?
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.
What did marsupials evolve from?
Marsupials (Metatherians) are thought to have evolved, along with placental (Eutherian) mammals, from Therian mammals. Marsupials diverged from Eutherian mammals approximately 90 million years ago.
How do platypus exist?
The platypus, found only in Australia is one of the five mammal species of that lay eggs instead of giving birth to live young. The reason that odd, egg-laying mammals still exist today may be because their ancestors took to the water, scientists now suggest. …
Why is the platypus so unique?

How long have platypus been alive?
What is the evolution of the platypus?
There’s a good account of the history of the evolution of the monotremes in How the Venomous, Egg-Laying Platypus Evolved 280 million years ago, mammal-like reptiles separated from other reptiles and birds. 80 million years ago, monotremes (egg-laying mammals) separated from other mammals.
Do platypus give birth or produce milk?
While milk production and giving birth to live young would seem to go hand in hand, the platypus genome shows that the two common mammalian traits evolved at very different points in evolutionary time.
Why does the platypus not want to join the family?
The birds, marsupials, and fish each implore the platypus to join their particular family. After consulting with the echidna, the platypus graciously declines, explaining that it shares traits with all groups and wishes to remain friends with all of them, rather than belong to one single group.
How does a platypus produce venom?
Male platypuses produce a pain-inducing, snake-like venom, composed of at least 19 different substances, which is delivered to enemies or rival males through spurs on the males’ hind legs. Previous studies of venomous snakes had found that poison production is the result of evolutionary modifications to genes that once served other functions.
