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. Connecting links provide the evidence for the path of evolution and lie midway between the two groups that is they have features of both the groups of organisms.

This page has been archived and is no longer updated.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. Rather, birds are included in this diagram because they are contemporary representatives of the sauropsid lineage, a group of reptile cousins that split from our family tree roughly million years ago. So, if monotremes aren't part bird, why did the investigators who conducted the platypus study examine genomic data from chickens during the course of their research? The primary reason for inclusion of this data relates to comparison.

At the same time, it possesses hair and mammary glands that are the characteristic features of mammals.

Animals exhibiting characters of two adjacent taxonomic groups are called connecting links. They afford very good evidence of organic evolution. The following are the important connecting links:. Peripatus is a living connecting link between arthropods and annelids. Its arthropods characters are claws, jaws, hemocoel, tracheae, and dorsal tubular heart.

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. A new study indicates that the distinctive mammal's genetic code is an eclectic brew of bird, reptile and mammal. This mix-and-match animal is more than just an oddity, though.

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.
