Paleo Got It Wrong: We've Loved Carbs for Over 100,000 Years | SciShow News

The video explores the evolution of human diet, challenging the Paleo diet's claims by presenting genetic and archaeological evidence of ancient starch consumption. It highlights the Amy1 gene's role in starch digestion and archaeological findings of early starch cooking. Additionally, it discusses a yeast genus, Hanzenia Spora, which has lost essential genes yet survives, suggesting rapid evolution and adaptation. This yeast's study may reveal insights into life's basic processes, showing that gene loss can be as adaptive as gene creation.

What does the presence of multiple copies of the Amy1 gene in humans suggest about their diet?

• Humans have always been carnivores.

• Humans have a genetic predisposition to avoid starches.

• Humans have a long history of consuming starches.

• Humans only started eating starches 10,000 years ago.

What archaeological evidence supports the idea that humans consumed starches long before agriculture?

• Fossilized meat remains

• Charred food remains and starch granules in teeth

• Ancient tools for hunting

• Cave paintings of animals

What is unique about the yeast genus Hanzenia Spora?

• It has more genes than any other yeast.

• It has lost several genes considered essential for life.

• It is the slowest evolving yeast.

• It is only used in bread making.

How does the yeast Hanzenia Spora manage to survive despite losing essential genes?

• Other genes may compensate for the lost ones.

• It relies on other organisms for survival.

• It has developed a new set of essential genes.

• It does not actually survive.

What evolutionary advantage might rapid mutation provide to organisms like Hanzenia Spora?

• It reduces their ability to reproduce.

• It makes them more susceptible to diseases.

• It helps them adapt to a rapidly changing environment.

• It allows them to remain unchanged.

What does the study of Hanzenia Spora suggest about the nature of essential genes?

• All genes are equally important.

• Only new genes are important for evolution.

• Some genes thought to be essential may not be.

• Essential genes cannot be lost.

What does the phrase 'life finds a way' imply in the context of the yeast study?

• Life can adapt in unexpected ways.

• Life is dependent on a fixed set of genes.

• Life cannot survive without essential genes.

• Life is static and unchanging.
