Summary Introduction
To describe: The relationship of the animals such as
Introduction: Photoreceptors are the sensory receptors present in the eye that detect light. These photoreceptors absorb light energy and cause a change in the action potential. Certain pigments present in the receptors called rhodopsin are sensitive to light and help in signal transduction.

People who object to evolution sometimes assert that complex organs such as eyes are irreducibly complex, and therefore
couldn't have arisen through evolution. Which of the following are insights that evolutionary research has provided on how
complex organs arise? For each choice select YES or NO.
Axonal growth cones from amphibian retinal ganglion cells are directed to their tectal
targets by
a) ephrin receptor gradients in the tectum.
b) ephrin ligand gradients in the retina.
c) ephrin ligand gradients in the tectum.
d) slit gradients in the retina.

The following passage comes from an abstract in a study about analyzing hearing
loss in twins:
"A clinical and genetic study on 25 twin pairs with at least one deaf member was
performed. Concordance rate of hearing loss was 0.88 in MZ and 0.50 in DZ pairs"
(MZ =monozygotic or identical twins. DZ -Dizygotic or fraternal twins). From this
data alone, what can you conclude about the roles of environment and genetics in
hearing loss? Explain how you reached your conclusion.

- Many people like to eat spicy foods, but most other mammals don’t. Historically, the general trend was that the hotter the climate, the spicier the foods a society traditionally favored. Using these facts as a starting point, what might be the selective advantage for plants that can manufacture spicy chemicals? Why might it be useful for humans to tolerate, and even enjoy, spicy food?arrow_forwardEyes are often used in arguments for intelligent design because many consider this organ to be too complex to have evolved by chance alone. However, complex lensed eyes evolved independently both within cephalod mollusks and vertebrates including our own ancestor. In the evolution of these structures the corresponding phylogenies revealed that both: A) were preceded by the evolution of 'simple' light sensing eyes, thus having adaptive intermediate evolutionary steps. B) lacked intermediate evolutionary steps involving the evolution of 'simple' eyes. C) had intermediate evolutionary steps, but ultimately the vertebrate eye had a superior 'design' without any kind of blind spot, relative to the simple invertebrate cephalopod eye. D) were preceded by vestigial non-functional optic structures.arrow_forwardThe phylogeny in this figure shows the evolution of visual opsins in tetrapods.

- Evolutionary biologist Neil Shubin once said, "In one sense, evolution didn't invent anything new? It's using the old to make the new, and we call that tinkering." How does the concept of the evolution of the complex eye and the idea of exaptations support Dr. Shubin's statement? Explain and give an example.arrow_forwardHow can the Darwinian concept of descent with modification explain the evolution of such complex structuresas the vertebrate eye?arrow_forwardReview how photoreceptors within the eye detect light and transmit that information to the brain, by identifying each lettered structure in the figure below and answering the questions that follow: A: B: C: D: E: F: G: Which structure responds to color?: Which structure responds to dim light and movement?: Which two structures release neurotransmitters in response to light?: Which structure binds to those neurotransmitters, relays an action potential, and releases a second set of neurotransmitters?: Which structure binds to this second set of neurotransmitters and relays an action potential through the optic nerve to the brain?: Which direction does light travel through the retina?

- Which of the following best describes the evolution of smell in chordates? A) Ancestrally, jawless fish had few ancestral scent genes that coded for receptors resembling a combination of water and air receptors. Subsequently these genes were duplicated and specialized through natural selection either for use in water or air. B) Ancestrally, all olfactory receptors where specialized for water as the ancestor of all vertebrates was aquatic. Only once did olfactory genes become duplicated and specialized and this was in the transition to land for receptors that work in air. C) All chordates share the same number of scent receptor genes. However, they have become variously deactivated through natural selection due to either unuse or a tradeoff for sight genes. D) None of the above.arrow_forwardRegarding the evolution of the mammalian inner ear, the above diagram shows:A) the co-option of jaw bones (colored) for use in hearingB) the loss of jaw bones (colored) and the origin of de-novo hearing bones C) the evolution of synapsids, which have little to do with mammalian evolutionD) the results of a population bottleneck which led to the fixation of odd alleles for ear developmentarrow_forwardWhich of the following statements about sensory systems is NOT true? a. Sensory transduction involves the conversion (by either a direct or indirect mechanism) of a physical or chemical stimulus into changes in membrane potential difference. b. Sensory adaptation plays a role in the ability of organisms to discriminate between important and unimportant information. c. The term "sensory adaptation" refers to the process by which a sensory cell becomes less sensitive, or less responsive, to a continuing source of stimulation. d. In general, a stimulus causes a change in the flow of charged ions across the plasma membrane of a sensory receptor cell. e. The more intense a stimulus is, the greater the peak depolarization of the action potentials fired by the sensory neuron.arrow_forward
