Two whale species evolved in different oceans from a common ancestor.Identify how the similarity in their DNA is likely to change over time.*1 pointTheir DNA will become more similarTheir DNA will become more differentTheir DNA will remain the sameCannot determine

Closely related speciesMultiple Choicehave identical DNA.have similar amino acid sequences in some proteins.have undergone the same environmental pressures and have adapted in the same ways.have the same mutation rates in their gene structure.

You compare the genomes of two species and determine some very large differences. This would suggest that the two species Blank______.Multiple choice question.do not share a common ancestorare not very closely relatedare very closely related

MULTIPLE CHOICEWhich of the following lines of evidence supports the concept of natural selection?A the strong similarities in the features and traits of organisms found on different continents and isolated islandsB the random occurrence of new traits in a populationC the absence of similarities in DNA sequences among closely related speciesD the existence of transitional fossils shows gradual changes between different species

Which is the most effective way to determine if two species are closely related?1 pointCompare their body structuresCompare the food that the two species eatCompare the habitats in which they liveCompare their DNA sequences

3. Apply the molecular clock concept to the data in the table below. Explain which of the three species in the table shared the most recent common ancestor with the human species.SpeciesPercent of DNA that is the Same as Human DNAThink CriticallyCompare and contrast relative and absolute dating.How did scientists use fossils to solve the mystery of whale evolution?
