3 Incredible Examples of Evolution Hidden In Your Body

The video explores the evidence of evolution found within the human body, such as vestigial structures and chromosomal changes. It highlights the fusion of chromosomes in humans compared to other apes, the presence of pseudogenes like NANOG, and the remnants of egg yolk genes, demonstrating shared ancestry with other species. The narrative emphasizes that evolution is a shared story of life, offering a different kind of magic in understanding our origins.

Which of the following is a vestigial structure in humans that indicates our evolutionary past?

• Appendix

• Heart

• Liver

• Lungs

What is unique about human chromosome 2 compared to other apes?

• It is missing entirely.

• It is fused from two separate chromosomes.

• It has no centromeres.

• It is larger than any other chromosome.

What are pseudogenes?

• Non-functional copies of genes

• Genes that have been duplicated and remain functional

• Functional genes that code for proteins

• Genes that are only found in humans

How do pseudogenes like NANOG spread in the genome?

• By being inherited from the mother

• By being copied from RNA back into DNA

• Through environmental factors

• Through natural selection

What is the significance of finding the same broken copies of NANOG in both humans and chimpanzees?

• It proves that NANOG is a functional gene.

• It shows that humans evolved from chimpanzees.

• It indicates a unique mutation in humans.

• It suggests a recent common ancestor.

What is the role of the yolk sac in human embryos?

• It provides nutrients like in bird eggs.

• It forms the shell of the egg.

• It is a vestigial structure with no yolk.

• It helps in respiration.

What evidence supports the evolutionary link between humans and egg-laying animals?

• Presence of a shell in human embryos

• Fragments of vitellogenin gene in human DNA

• Humans lay eggs in early development

• Humans have a fully functional yolk sac
