All wrong.
I would expect you to read scientific articles and watch videos we post here if you want some answers, now you post outdated crap and think we will take you seriously?
Platypus egg laying retained not from birds - it is from reptiles. And they are not the only mammals with this ability. Echidnas split from Platypuses millions of years ago but still retained same egg laying ability.
...outdated? Everything you guys produce is "outdated" with wild speculation, extravagant time elements, and ridiculous assumptions that have already been disproved, discredited and proven outright falsehoods!
But to satisfy your need for "updated" stuff I give you this!
The platypus poses some interesting problems for evolutionary scientists. Here is a creature that appears to be right in the middle of a supposed evolutionary transition, yet fossils dated to millions of years ago look almost identical to the modern animal.
If the platypus is a transitional specimen,
why did it seemingly stop evolving? Why has it remained virtually unchanged for its entire existence?
Even the minor changes are disappointing to scientists, as they could
more aptly be considered de-evolution. For instance, the fossilized adult platypus had functioning teeth. Yet modern platypuses lose their teeth at an early age, leaving only a horned plate with which to grind and mash their food to a pulp, prior to swallowing.
Hardly advancement at all!
Further, consider the watery environment in which a platypus survives—in fact, thrives. (When a platypus is removed from its natural habitat, its lifespan is greatly abbreviated.)
As with many other mammals, it has eyes, ears and a nose. All three are fully functioning and would serve a platypus well if it spent much time on land. On the other hand, its heavily webbed front feet mean that it is forced to walk on its knuckles, or risk damaging the somewhat fragile webbing. In the water, the beauty of the animal’s design becomes apparent. It maneuvers gracefully with speed and precision while foraging for food.
Though it spends the majority of its time in water, the platypus never evolved an ability to hold its breath for very long, typically no more than 30 seconds. How is it that an animal living primarily in the water for “millions” of years
still cannot hold its breath for more than half a minute?
Imagine the hypothetical evolutionary path of this extraordinary creature. Suppose there was a time before all of the animal’s features were fully formed. (The fossil record demonstrates no such instance.) These early platypuses would have had no webbed feet or electrolocation system. Instead of gliding skillfully through the water, this poor animal would have flailed about, with no method to navigate or find food.
(Yet, somehow, over millions of years, it would have managed to survive drowning, starvation and predators.)
Over time, the platypus would have “decided” that webbed feet were needed, and evolved a version unlike that of any other creature. Then, instead of its eyes, nose and ears adapting to work underwater, it evolved a device that looks like a duck’s bill, but instead
is the most advanced electrolocation system found on any mammal.
Given this unlikely scenario, this must have happened another way. The
fossil record indicates that the platypus appeared fully formed, with all of its “adaptations” perfectly balanced.
