In the lineage leåding to tetrapods, the fins of aquatic wertebrates evolved into the limbs of terrestrial vertebrates. Give two pieces of evidence that support this hypothesis, and briefly describe the selective pressure(s) that led to the evolution of limbs in early tetrapods (Note - your answer should specifically address the evolution of limbs, not the general selective pressures for moving to a terrestrial environment).

MAKE CONNECTIONS Historically, annelids and arthropods were viewed as closely related because both havebody segmentation. Yet DNA sequence data indicatethat annelids belong to one clade (Lophotrochozoa) andarthropods to another (Ecdysozoa). Could traditionaland molecular hypotheses be tested by studyingthe Hox genes that control body segmentation (seeConcept 21.6)? Explain.
A genetic change that caused a certain Hox gene to be expressedalong the tip of a vertebrate limb bud instead of farther backhelped make possible the evolution of the tetrapod limb.This type of change is illustrative of(A) the influence of environment on development.(B) paedomorphosis.(C) a change in a developmental gene or in its regulation thataltered the spatial organization of body parts.(D) heterochrony

Explain how these embryos can be used as evidence of a common ancestor between each of these six organisms.

MAKE CONNECTIONS Many new animal body plansemerged during and after the Cambrian explosion. Incontrast, cnidarians today retain the same diploblastic,radial body plan found in cnidarians 560 million yearsago. Are cnidarians therefore less successful or less “highlyevolved” than other animal groups? Explain.(See Concepts 25.3 and 25.6.)
EVOLUTION CONNECTION Living members of a vertebratelineage can be very different from early members of the lineage,and evolutionary reversals (character losses) are common. Giveexamples that illustrate these observations, and explain theirevolutionary causes.
Nimravids Skeleton vs Siberian Tiger Skeleton vs Smilodon Necator SkeltonCompare and contrast the appearance of specific bones in the skeleton. Compare the skeleton of the extinct creatures with the extant creature, and with themselves. How might the variation in anatomy link to the likely function? Compare species' skeletal anatomy based on life history (aquatic vs terrestrial). What are other interesting factors noted in the skeletons?
Q5. Lungs allow an animal to breathe _____________. Why did this adaptation evolve? Q6. Tetrapods use ____________ to breathe. Do any modern tetrapods have gills? Explain. Q7. How did the anatomy of the shoulder and head change during tetrapod evolution? Q8. Acanthostega and Icythyostega have been called fish-like tetrapods. Explain why they are described as such and describe the environment in which they probably lived. Q9. __________________ and _____________________ are early tetrapods that do not have features unique to fish. Describe how these two species differ anatomically and what that means about where they each lived.
