Concept explainers

Genetic Evolution

Sexual reproduction produces distinct population variations. Heredity determines the traits and qualities to be passed down to the progeny. Over time, this variation within-species is also affected by the process of human evolution. The study of how genetic variation leads to evolutionary changes is known as genetic evolution. If a trait helps an organism to survive and reproduce, it is more likely to be passed down the generations. It is rare that such traits result in a completely distinct set of traits in descendants than the ancestral population; this can result in the emergence of a new species.

Question

Geneticists can synthesize any gene—any stretch of DNA—
desired. Suppose you use a tree of genome evolution to predict
the structure of a now nonexistent, ancient gene. What insights
might you obtain by synthesizing the ancient gene and inserting
it into a living animal?

Geneticists are currently considering using technologies described in this chapter to de-extinct thewoolly mammoth, a species that disappearedroughly 4000 years ago.a. Frozen specimens of woolly mammoths have beenfound in the Siberian tundra. If intact, living cellscould be obtained from these samples, how couldyou attempt to bring back these long-extinct animals using these cells and oocytes from Asian elephants, a closely related species? b. Scientists have determined the genome sequence ofthe mammoth from frozen samples. These researchers are now trying to understand the adaptations that allowed these creatures to surviveextreme cold. For example, mammoths had muchthicker hair than do any elephants.
