Why is the evolution of the amniotic egg significant?
O Embryos are protected from predators.
O Tetrapods are no longer tied to the water for reproduction.
○
Tetrapods can now function with just lungs.
O Newborns are much less dependent on their parents.
It is believed that the coelacanths and lungfish represent a crucial link between other fishes and
tetrapods. What is the major feature in these fish in support of this hypothesis?
O Like amphibians, they are tied to the water for reproduction.
Their fins have skeletal and muscular structures similar to amphibian limbs.
They have lungs and are able to breathe air when water is scarce.
O They have highly evolved nervous and circulatory systems.
They enter a hibernative stage when food is scarce, as many tetrapods do.

- Discuss the idea that every evolutionary adaptation has both advantages and disadvantages, using each of the following as an example: (a) cephalization,(b) the arthropod exoskeleton, and (c) segmentation with specialization.arrow_forwardpart i Animal phylogenies based on molecular and morphological characters can be different in regards to the placement of the phylum Platyhelminthes. What is the best explanation for this?choose 1 a. The Platyhelminthes clade separated from other clades before coeloms evolved and consequently Platyhelminthes have never had a coelom. b. Some Platyhelminthes have a coelom, but others do not and it is difficult to conclude anything about its evolution within the clade. c. Platyhelminthes originated from ancestors with a coelom and have retained it to the present time. d. Modern Platyhelminthes do not have a coelom but did originate from an ancestor that had one. e. Platyhelminthes evolved from an ancestor without a coelom but developed one during the course of their evolution. part ii If current molecular phylogenies of land plants are correct and to be believed they suggest that.

- On a deep sea expedition, you capture a previously undiscovered sea creature that appears to represent a new phyla. It happens to have fertilized eggs that you get to spawn. You watch its development to determine which group of animals it might belong to. You see that the mouth develops first, and it goes through several larval stages in which it molts and regrows its skeleton. What other traits is it likely to have based on this type of development Radial symmetry Coelem Central Nervous System Two germ layers present yes or no for eacharrow_forwardIs the presence of myomeres a symplesiomorphic or synapomorphic feature of vertebrates compared to conditions in other deuterostome metazoans?

- The Tetrapoda is a taxon defined partially on the basis of synapomorphic character state '4 limbs.' Heidi Theory declares as a polyphyletic group for study the 'Apodial Amniota' containing only two groups, each lacking limbs. As a BIOLOGY student, you immediately recall two groups considered in this course, which have evolved to no longer develop completely their limbs, consistent with Heidi's declaration. Input into each box presented below exactly and precisely one word, the common name for one group – lizards, for instance; please use the plural forms Question 3 options: Blank # 1 Blank # 2arrow_forwardTRUE OR FALSE 1. The fossil record provides a sweeping overview of the history of life over geologic record 2. A change in the regulation of a developmental gene may have fewer harmful side effects than a change to the sequence of the gene. 3. Synapsids possess an opening known as the occipital fenestra behind the eye socket 4. In some very late cynodont the articular and quadrate bones migrated into the ear region, where they functioned in transmitting sound 5. Fossils contain isotopes of molecules that accumulated in the organisms when they were alive.arrow_forwardA swim bladder is a gas-filled sac that helps fish maintainbuoyancy.
