This page has been archived and is no longer updated. 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 million years ago, deep in the Mesozoic era, and since that time, it has independently lost different elements of our last common ancestor. By comparing bits of the platypus genome that were conserved with those that were lost, researchers can develop a clearer picture of what Jurassic mammals were like, and they can also determine what sorts of genetic traits contemporary mammals have gained and lost over the course of evolution. In order to better understand the impact of the platypus study, it is helpful to begin by looking at a cladogram that illustrates the dates when derived traits appeared in the various lineages considered in the study Figure 1. This diagram reflects a fairly conventional picture of our evolutionary history, and it reinforces the evolutionary explanation for the illustrated relationships. As you can see, a number of modern animals—including birds—are depicted along the top of the cladogram in Figure 1. Note, however, that the cladogram does not imply that modern monotremes including the platypus are part bird.

At iwis you will find the right connecting link for every roller chain: Outer link, Inner link, Spring connecting link, Connecting link cotter pin type, Single crank link, Double crank link. An intermediate or transitional condition is a connecting link between two taxonomic classes of organisms. A connecting link has characters that are common to both groups of organisms. Connecting link is an organism having characteristics of two different group of organisms e. Some well-known examples for connecting links are Archaeopteryx, Duck-billed platypus, Lungfish, Seymouria, Balanaglossus, Peripatus.

One well-known illustration of a connecting link is the dinosaur Archaeopteryx, which resembled a bird and lived around million years ago. Archaeopteryx features feathers and a long, bony tail, as well as traits from both avian bird and reptile animals. This makes it a crucial piece of proof supporting the idea that tiny, feathered dinosaurs gave rise to birds. The mammal-like reptiles, a group of reptiles that existed during the Mesozoic era and possessed several traits similar to those of mammals, including fur, nipples , and the capacity to control their body temperature, are another illustration. These animals demonstrate how mammals may have descended from reptile-like ancestors and offer proof of the evolutionary link between reptiles and mammals. Because they demonstrate the shared ancestry of many groups of creatures and assist to fill in the gaps in the fossil record, connecting linkages are crucial to evolutionary theory. They also aid in illuminating the evolutionary process and demonstrating how species have changed over time. Overall, connecting links play a crucial role in understanding the evolution of life on Earth and demonstrate how species are related through a common ancestry.

The platypus Ornithorhynchus anatinus is an odd-looking creature whose features combine the furry torso and wide, flat tail of a beaver with the rubbery bill and webbed feet of a duck. But its looks are not all that is strange about it.
