Chapter 18, Problem 8TYU
SYNTHESIZE YOUR KNOWLEDGE
Insects have three thoracic (trunk) segments. While researchers have found fossils with wings on all segments, modern insects have wings or related structures on only the second and third segments. Hox gene products inhibit wing formation on the first segment. The treehopper is an exception. Its first segment has an ornate helmet that is a modified fused pair of "wings." which provide camouflage in branches, reducing risk of predation. Explain how changes in gene regulation could have led to this evolution.

Evolution in Humans
1) explain how differences in gene expression of genetically similar organism can result in
different evolutionary outcomes
2) describe the evolution of symbolic thought in humans
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.
An organism has a relatively large number of Hox genes in its genome. Which of the following is true
of this organism?
Select one:
А.
Its Hox genes cooperate to bring about sexual maturity at the proper stage of development.
В.
Most of its Hox genes owe their existence to gene fusion events.
С.
The organism must have multiple paired appendages along the length of its body.
D.
These genes are fundamental, and are expressed in all cells of the organism.
E.
The organism has the genetic potential to have a relatively complex anatomy.

- . Complete genome sequences indicate that the humangenome has roughly 27,000 genes, while the worm(nematode) genome has about 22,000 genes. Explainhow the human genome with only about 20% moregenes can encode a creature enormously more complex than the worm.arrow_forwardDominguez et al. (2004) suggest that by studying genes that determine growth and tissue specification in the eye of Drosophila, much can be learned about human eye development. (a) What evidence suggests that genetic eye determinants in Drosophila are also found in humans? Include a discussion of orthologous genes in your answer. (b) What evidence indicates that the eyeless gene is part of a developmental network? (c) Are genetic networks likely to specify developmental processes in general? Explain fully and provide an example.arrow_forwardA graduate student performing studies on mutations in drosophila (fruit flies) discovered a strain of flies with a silent mutation in the gene controlling the shape of the wings. Further investigation has shown that this mutation is lethal in flies who are homozygote. Flies that are homozygote wild type or heterozygote can develop and are able to survive. What is a silent mutation (in your own words) and propose a hypothesis that could explain these observations using concepts learned.

List all the properties of such mutations. How does the Antennapedia gene change antennae into legs?arrow_forwardEVOLUTION CONNECTION Genes important in the embryonicdevelopment of animals, such as homeobox-containing genes,have been relatively well conserved during evolution; that is,they are more similar among different species than are manyother genes. Explain why this is.arrow_forward
- Absence of bicoid mRNA from a Drosophila egg leads to theabsence of anterior larval body parts and mirror-imageduplication of posterior parts. This is evidence that the productof the bicoid gene(A) normally leads to formation of head structures.(B) normally leads to formation of tail structures.(C) is transcribed in the early embryo.(D) is a protein present in all head structures.arrow_forwardYou have identified a Drosophila gene that is expressed exclusively in the odd-numbered "stripes" in the cellular blastoderm. Assuming that this gene is not redundant, what would be the most likely phenotype cause by a loss-of-function mutation in this gene? an embryo missing odd numbered segments an adult fly with a second pair of wings instead of halteres an embryo with two anterior ends an embryo missing even-numbered segments an embryo missing larval segments 3-10arrow_forwardInsect wings are coded for by the same gene that creates...

- The sequence of genes in a hypothetical animal cell is normally A-B-C-D. This results in normal development. Due to a mutation, the genes change position (A-C-D-B) resulting in abnormal development. This research was originally conducted and verified by which biologist?arrow_forwardHomeotic (Hox genes in vertebrates) code for expression of that regulate the OD) Transcription factors, genes that determine segment identity and structure OC) Poly-A tails, that code for proteins that control muscle differentiation OE) Transcription factors, genes that control muscle differentiation OA) Operators, inducible genes coding for enzymes in metabolic pathwaysarrow_forwardRecall from our classes on molecular evolution that some proteins evolve more rapidly than others. For example, the oxygen-carrying protein myoglobin evolves more quickly than the D1 protein of photosystem II. What explains this difference in the rate of protein evolution? A. Proteins like myoglobin have evolved more recently than proteins like D1 and thus have been forced to evolve more quickly. B. Changes to the sequence of some proteins can be tolerated as they don’t alter fitness; for other proteins, sequence changes are usually harmful. C. In constrained proteins like D1, evolution results primarily from nucleotide changes that alter the amino acid sequence of the protein. D. Protein evolution is dependent upon the rate of gene mutation and some genes have a higher rate of mutation than others.arrow_forward
