Consider this example. Shorebirds on the Eastern coast of North America feed on the mollusks and tiny crabs along the shore. Birds with tougher beaks are better adapted to crack open the shells of the mollusks, and birds with sharper beaks are better adapted to pierce the shells of crabs. Over time, the shorebirds become two separate species that no longer breed with one another. What type of speciation has occurred? A. Sympatric speciation B. Adaptive speciation C. Microevolution speciation D. Allopatric speciation
Which of the following factors would not contribute toallopatric speciation?(A) The separated population is small, and genetic drift occurs.(B) The isolated population is exposed to different selectionpressures than the ancestral population.(C) Different mutations begin to distinguish the gene pools ofthe separated populations.(D) Gene flow between the two populations is extensive.
compare and contrast between the following a) allopatric speciation and sympatric speciation. b) autopolyploid speciation and allopolyploid speciation c) natural selection and sexual selection
Explain your answer in some depth and avoid just saying "It is A" or It is B. Defend your answer and explain why you choice that answer choice. Question: Domestic dogs would least likely meet the definition of a single species using which concept? Group of answer choices A) Lineage B) Biological C) Morphological D) Domestic dogs are not a single species according to any of the species concept definitions.
Select the correct terms: Speciation due to geographic separation and (genetic divergence / gene ﬂow) of two populations is considered (allopatric / sympatric) speciation
How does one species diverge from another? (When do we call a group a new species—and how does that process happen?) Using anole lizards or another very specific example(s), compare and contrast microevolutionary processes with speciation. As you discuss speciation, be sure to compare and contrast sympatric speciation with allopatric speciation and say whether the example you’ve chosen is allopatric or sympatric.
Options are a. Hybrid offspring. b. Speciation c. Adaptive radiation. d. Mechanical isolation.
If reinforcement is weak and hybrids are not completely infertile, a. genetic divergence between populations may be overcome by gene flow. b. speciation will occur 100% of the time. c. gene flow between populations will be impossible. d. the speciation will be more likely than if hybrids were completely infertile.
Vicariance describes a fundamental process preventing gene flow which is part of Select one: a. sympatric speciation b. parapatric speciation c. allopatric speciation
A) Differentiate allopatric speciation and sympatricspeciation. Which type of speciation is more common andwhy? B) Is allopatric speciation more likely to occur inDumaran Island close to the main island of Palawan oron a more isolated island which is Culion Island of almostthe same size? Explain your prediction.
n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive data
Indicate the order in which the following steps would take place to result in Sympatric Speciation [enter 1 for the first step, 2 for the second, etc; write only the number -- no words, no spaces] As they adapt to their specific environments, the fitness of any hybrid formed is reduced. Reproductive isolating mechanisms are selected for so that less fit hybrids are not formed. Two species now exist. Interbreeding populations connected via gene flow occur across a range. The populations in the new environment adapt to their particular circumstances while the remainder stay as they were. Something happens so that some members of the populations/species change their environment (shift hosts; have a genetic change like polyploidy or inversions), so that they are separated from the others even thought hey are living in the same area.
