Neopilina is the connecting link between Annelida and Mollusca.

Neopilina is a connecting link between phylum Annelida and Mollusca. It is highly derived genus of modern monoplacophoran(class of species annelids and molluscs).

Note: Peripatus is a connective link between arthropods and annelids since they have characteristics of both annelids and arthropods. As annelids, peripatus have worm-like segmented body, segmental nephridia, etc. and as arthropods, they have jointed pairs legs. Hence, they are the connecting link of both the groups.

Seymouria between reptiles and birds. Hint: Connecting link is an organism with characteristics of two different groups. … Some well-known examples for connecting links are Archaeopteryx, Duck-billed platypus, Lungfish, Seymouria, Balanaglossus, Peripatus.

Neopilina – it is regarded as a connecting link between Annelida and Mollusca. Archaeopteryx – it serves as a connecting link between reptiles and birds. So, the correct answer is “Annelids and arthropods”.

Connecting link is an organism having characteristics of two different group of organisms e.g, duck-billed platypus ( scientific name Ornithorhynchus anatinus) is a connecting link between reptiles and mammals i.e, it has mammary glands to feed its young ones like other mammals e.g human being, cow, buffalo etc., and …

Seymouria: It is a connecting link between amphibian and reptiles. It is a lizard like animal.

Archaeopteryx is known to be a communicating connection between reptiles and birds because it looks like a bird and has bird wings. The teeth and tail, however, are closer to those of reptiles. Since it implies that birds evolved from reptiles. Therefore Archaeopteryx links reptiles and birds.

A semi-aquatic egg-laying mammal discovered in Tasmania and Australia is the duck-billed platypus. … It is a connecting link between reptiles and mammals, as it has both reptile and mammal features.

Option A: Lungfish Protopterus is a connecting link between fishes and amphibians. It has the characteristics of both the fishes and amphibians in them. It is also considered as the missing link between fish and amphibians.

Hemichordata (Balanoglossus): it is the connecting link between Echinoderms and chordates.

Balanoglossus is the connecting link between chordates and non-chordates.

Archaeopteryx. Hint: Duck-billed platypus is the connecting link between reptiles and mammals, as it has both reptiles and mammals’ features.

What are the characteristics of Peripatus?

Peripatus resembles the arthropods in the following characteristic features:

  • Presence of antennae.
  • Body is covered with chitinous cuticle like that of arthropods.
  • The appendages are provided with claws.
  • Jaws are modified appendages.
  • Locomotion is not annelid-like but by legs having definite musculature.

How old is the Seymouria?

Seymouria, extinct genus of terrestrial tetrapod found as fossils in Permian rocks (251 million to 299 million years old) in North America and named for fossil deposits near Seymour, Texas.

Is a Seymouria a reptile?

Seymouria is an extinct genus of Seymouriamorph from the Early Permian of North America and Europe. Although they were amphibians (in a biological sense), Seymouria were well-adapted to life on land, with many reptilian features—so many, in fact, that Seymouria was first thought to be a primitive reptile.

Seymouria is a connecting link between A Aves and mammals class 10 biology CBSE.

Connecting link is an organism having characteristics of two different group of organisms e.g, duck-billed platypus ( scientific name Ornithorhynchus anatinus) is a connecting link between reptiles and mammals i.e, it has mammary glands to feed its young ones like other mammals e.g human being, cow, buffalo etc., and …

Significance. 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. These confirm evolution of amphibians from fishes; mammals from reptiles ; arthropods and molluscs from the annelids.

NEET Question

PERIPATUS is a connecting link between ANNELIDA and ARTHROPODA… LIMULUS is a living fossil also known as KING CRAB…so option D is correct..

Is Neopilina a living fossil?

Neopilina is a mollusc, the only surviving genus of monoplacophora. … It was found to be a Monoplacophoran, and given the genus of Neopilina. This was one of the most remarkable modern discoveries of a ‘living fossil’, and a Lazarus taxon.
