The following image is from a scientific publication by paleontologist Niel Shubin, who was part of a team who discovered the earliest known tetrapod, Tiktaalik. What does
the image say about the bones in the fins of fish (on the left side) when compared to the bones in their tetrapod ancestors (on the right side)? (Image from Shubin et al.,
2006).
Gyptolepis
Suriptens
Eusthenopteron

- Which of the following is the correct classification for this chordate animal: This vertebrate starts its life cycle in the water in a form without legs. the adult form is a tetrapod and lives mostly on land. These animals do not have a tail and they are specialized for movement like jumping to capture prey. Question 26 options: a) Birds b) Cephalochordata c) Monotreme d) Class Chondrichthyes e) Urodela / Salamanders f) Anura / Frogs g) Eutharia h) Reptiles (non avian) i) Marsupial j) Superclass Agnatha k) Class Osteichthyesarrow_forwardWhich of the following is the correct classification for the following chordate animal: This animal has a skeleton made of bone. Most modern day fish are in this group. They use gills to breathe and have a swim bladder to help control buoyancy. They also have a lateral line to detect vibrations in the water.

- Only eight species of lobe-finned fishes are alive today, remnants of a group that flourished in the Devonian period of the Paleozoic era. What morphological characteristics distinguish lobe-finned fishes? What is the literal meaning of Sarcopterygii, the taxon comprising lobe-finned fishes and tetrapods?arrow_forwardAn important evolutionary innovation and a major difference between the limbs of extant lobe-finned fish and extant tetrapods is: Select one: 1. The presence of lobes on the fish fins. 2. Retention of fin rays in tetrapod limbs. 3. Limbs of tetrapods have associated muscles. 4. Limbs are supported by a single basal bone in tetrapods 5. Attachment of the pelvic limbs to the vertebral column via the pelvis in tetrapods. Please consider providing a detailed explanation of correct as well as incorrect options.arrow_forwardMammals belong to a group of amniotes known as synapsids.
