Genetic Diversity and Human Survival

Aiden and Ellie, the last humans on Earth, face the challenge of repopulating the planet. The video explores the risks of inbreeding, historical examples of genetic issues, and the potential for genetic diversity. Despite the challenges, there is hope for future generations, as seen in historical cases like Pingelap. Ellie and Aiden's story highlights the complexities of genetics and the possibility of repopulating the Earth, albeit with significant challenges and a need for luck.

What was the cause of the apocalypse that left Aiden and Ellie as the last humans?

• A deadly virus outbreak

• A massive asteroid impact

• An artificial intelligence uprising

• A nuclear war

Why is it beneficial that Aiden and Ellie are not related?

• It reduces the risk of genetic defects in their offspring

• It makes them immune to diseases

• It ensures they have different interests

• It allows them to live in different locations

What was a common practice among European royalty to keep the bloodline pure?

• Marrying commoners

• Inbreeding within the family

• Adopting children from other countries

• Using advanced genetic technology

What genetic condition was common in the Spanish Habsburg dynasty due to inbreeding?

• Hapsburg jaw

• Color blindness

• Albinism

• Sickle cell anemia

What is the role of recessive genes in genetic traits?

• They always determine the dominant trait

• They are never expressed in offspring

• They only affect hair color

• They require both alleles to be present to express a trait

What is the 'Founder effect' mentioned in the context of Aiden and Ellie's descendants?

• A process of natural selection favoring strong genes

• A genetic mutation that occurs in large populations

• A situation where a small population results in limited genetic diversity

• A phenomenon where a small population leads to high genetic diversity

What historical example gave Ellie hope for her descendants' future?

• The discovery of penicillin

• The rise of the Roman Empire

• The invention of the printing press

• The survival of the Pingelap islanders

What is the scientific consensus on the origin of modern humans?

• They were created by an advanced civilization

• They evolved from multiple types of early humans

• They originated from a single pair of humans

• They appeared suddenly without any ancestors

What is the minimum number of unrelated humans scientists believe is needed to repopulate a planet?

• 50

• 200

• 98

• 2

What is the main challenge in repopulating the Earth from just two individuals?

• Building advanced technology

• Ensuring sufficient genetic diversity

• Avoiding natural disasters

• Finding enough food and resources
