Which of these is NOT a necessary step in the speciation process? O Arisal of a barier to gene flow O Phenotypic innovation O Genetic and ecological divergence Reproductive isolation
Within a population of sunflowers, a new individual has a novel dominant mutation that causes it to flower 4 months earlier than the rest of the population. That sunflower survives and successfully self-fertilizes, leading over time to a novel population that evolves larger leaves and smaller flowers. This new population does not interbreed with the original population, although they are found in the same areas. This is an example of Allopolyploid speciation O Behavioral isolation O Allopatric speciation O Sympatric speciation O Adaptive radiation
Snakes evolved from ancestors who had the ability to walk. Some snakes, in fact, still have small pelvis and leg bones that are remnants from this ancestor. What are these caled? Vestiglal structure O Homologous strucre O Sympatric structure O Molecular homology In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. Of what is this an example? Founder effect
Incomplete lineage sorting happens when the ancestral species has loci with a great variety of allelic variations. In the case of human evolution, what does incomplete lineage sorting cause? O It causes that phylogenies using nuclear genes have less support than phylogenies using mitochondrial genes O It causes that primates can hybridize among species O It causes that phylogenies show that humans are more closely related to gorillas than to chimpanzees (and bonobos) It causes that phylogenies showing chimpanzees (and bonobos) more closely related to humans are less prone to error
Snakes evolved from ancestors who had the ability to walk. Some snakes, in fact, still have small pelvis and leg bones that are rermnants from this ancestor. What are these called? * O Vestigial structure Homologous strucre O Sympatric structure Molecular homology
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.
What must be present in order for separate populations to be considered separate species? microevolution O relative fitness O reproductive isolation O fossils
do taxa E F G by themselves form a monophyletic group (clade)? why or why not? Trait 2 E Trait 1 Ancestor 3 Ancestor 1 (Trait 2 not present) Trait 1 Trait 2 Trait 1 Ancestor 2 Trait 1
You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? * O Pre-zygotic barriers have forced them to be separate species. They are in Hardy-Weinberg equilibrium. O Microevolution is occurring in both variations. O They are two separate species.
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.
The difference between sympatric and parapatric speciation is ___. a. parapatric speciation occurs only in worms b. sympatric speciation requires a barrier to gene flow c. the extent of overlap in range d. reproductive isolation does not occur
Which of the following statements is true? Select one: O a Natural selection selects against those traits of an organism that bring it into a better adaptive relationship with its environment. Ob Natural selection favors those traits of an organism that bring it into a better adaptive relationship with its environment. Which of the following is not required for speciation to occur? Select one O a time Ob niche Oc. interbreeding Od genetic isolation
