Scientists Pull RNA from a 14,000 Year-Old Wolf | SciShow News

The video discusses the groundbreaking discovery of the oldest RNA sequence, estimated to be over 14,000 years old, challenging previous beliefs about RNA's longevity. This finding opens new avenues for understanding ancient organisms and viruses, as RNA can provide insights that DNA cannot. The video also highlights the discovery of a giant parrot species, Heracles Inexpectatus, in New Zealand, showcasing the phenomenon of insular gigantism and its impact on bird evolution.

What is the estimated age of the oldest RNA discovered?

• 7,000 years

• 14,000 years

• 70,000 years

• 700,000 years

Why is RNA considered more temporary than DNA?

• RNA does not carry genetic information

• RNA is more stable than DNA

• RNA is designed to be quickly broken down

• RNA is not found in cells

What can ancient RNA reveal that DNA cannot?

• The color of an organism's skin

• The exact age of an organism

• The conditions an organism experienced at the time of death

• The exact diet of an organism

What is the significance of finding ancient RNA in viruses?

• It helps in identifying the presence of viruses in ancient bodies

• It allows for the creation of new viruses

• It shows that viruses have not evolved

• It proves that viruses cannot survive for long

What is the estimated weight of the giant parrot Heracles Inexpectatus?

• 3 kilograms

• 5 kilograms

• 7 kilograms

• 10 kilograms

What phenomenon explains the evolution of large birds on islands?

• Genetic drift

• Adaptive radiation

• Insular gigantism

• Natural selection

Why were large birds able to evolve in New Zealand?

• Abundance of food

• Favorable climate

• Lack of predators and large plant eaters

• Isolation from other continents
