What distinguishes a morphospecies?
a. It has distinctive characteristics, such as size, shape, or coloration.
b. It represents a distinct branch in a phylogeny of populations.
c. It is reproductively isolated from other species.
d. It is a fossil from a distinct time in Earth history.
Introduction:
Morphology confers to the study of the structures of the organisms, involving its function, in order to classify organisms. Furthermore, morphology can be classified as functional morphology, molecular morphology, anatomy morphology, comparative morphology, and several other branches of morphology.
Answer to Problem 1TYK
Correct answer:
A morphospecies has distinct characteristics including color, shape, and size. The concept of the morphospecies is helpful in the identification of the morphologic features of the organisms.
Explanation of Solution
Explanation/justification for the correct answer:
Option (a) is given as distinction in the size, shape, and coloration. The term “morphospecies” have originated from morphology, which is used to indicate the difference in the body structure of the organisms; it could be color, size, or shape. It is based on the concept that isolated, independent gene flow results in the development of distinguished phenotypic features. Hence, Option (a) is correct.
Explanation for incorrect answer:
Option (b) is given as the representation of the population phylogeny. However, morphospecies is a term used to describe different species rather than a defining a branch in phylogenetic population (relation to the ancestors). So, it is a wrong answer.
Option (c) is given as reproductive isolation from another species. A morphospecies cannot be distinguished based on the reproductive isolation as none of the two different species can reproduce together. So, it is a wrong answer.
Option (d) is given as the presence of the fossil from some distinct time in the history of earth. A fossil is a preserved form of any individual, which is formed over a long period of time. So, it is a wrong answer.
Hence, options (b), (c), and (d) are incorrect.
Thus, the morphospecies can be distinguished based on its size, shape, and color.

- Why is reproductive isolation insufficient to define a species? A. Reproductive isolation doesn't take outgroups into account. B. This definition overlooks artificial reproduction, such as in zoos. C. This definition excludes organisms that reproduce asexually. D. Reproductive isolation can be accomplished in a variety of ways.arrow_forwardA scientist has developed 3 different phylogenies that describe the relationships between different species of elephants. In Phylogeny A, there are 4 total changes that resulted in 4 different species. In Phylogenies B and C, there are still 4 total species represented, however, they take 6 and 8 changes, respectively, to create them. Which phylogeny is probably correct? a.)Phylogeny A b.)Phylogeny B c.)Phylogeny C d.)All of the above, given every clade contains the same organismsarrow_forwardSieve tubes and sieve elements are a. homoplastic because they have different function. b. homologous because they have similar function. c. homoplastic because their common ancestor was single-celled. d. structures involved in transport within animalsarrow_forward
- What is true about organisms that are a part of the same clade? a. They all share the same basic characteristics. b. They evolved from a shared ancestor. c. They usually fall into the same classification taxa. d. They have identical phylogenies.arrow_forwardInsectivora is a taxonomic grouping that was used to describe insect-eating mammals like armadillos, hedgehogs, moles, and anteaters. The taxonomy of these animals has beea revised in recent years, and Insectivora is no longer widely accepted because this group of organisms lacks one common ancestor and is instead descended from several ancestors. Which term best describes Insectivora? A. Polyphyletic B. Monophyletic C. Haplophyletic D. Paraphyleticarrow_forwardA small number of birds arrive on an island from a neighboring larger island. This small population begins to adapt to the new food plants available on the island, and their beaks begin to change. About twice a year, one or two more birds from the neighboring island arrive. What effect do these new arrivals have? A. Their arrival tends to retard adaptation to the new food plants. B. Their arrival speeds the process of speciation. C. Their arrival tends to promote adaptation to the new food plants. D. Their arrival will likely prompt genetic drift. E. Their arrival represents a colonizing event.arrow_forward
- The three beetle species live in the same ecosystem, and they likely evolved from the ancestral species that colonized the region. Which statement best explains how descent with modification influenced speciation in these beetles? A. The ancestral species carried neutral gene mutations that spontaneously caused speciation when they colonized the region. B. The ancestral species randomly diverged into three species before colonization and then colonized the regions that best suited their new adaptations. C. After colonization, small groups separated from the rest of the ancestral species and developed different adaptations that helped them survive and reproduce. D. After colonization, the large group interbred until they developed enough neutral genetic mutations for speciation to occur.arrow_forwardGround beetles (Carabus solieri) have useless hind wings.

- Which statements are correct about the Domain System. Choose all that apply. A. It is more recent than the Kingdom System B. It takes into account phylogeny C. It was the first to introduce binomial nomenclature D. It is hierarchical in naturearrow_forwardSome embryos share many similarities and are difficult to tell apart, while others are slightly easier. What can you conclude about the similarities and differences between the embryos of different species? Select one: a. The more closely related species show differences from the earlier stages. b. The more closely related species share similarities until the later stages. c. The more distantly related species share similarities until the later stages. d. The more distantly related species show differences in only the later stages.arrow_forwardTwo different plants, cactus from the desert southwest USA and a euphorb from South Africa, have similar adaptations to desert life- these similarities evolved independently in response to similar environmental conditions, they were not inherited for one shared ancestor of cactus and euphords . What is the best term for these adaptations? A. Synapomorphies B. Acclimations C. Homologous traits D. Analogous traitsarrow_forward
