If we all are the descendants of the same person then how come our DNA are so distinct?
If all the humans are the descendants of the same person then how come our DNA's are different?
Why do all living creatures have DNA? Does a person's DNA SEQUENCE change through the course of their life? Are there any changes in an individual's DNA sequence over one's life? Why do humans have different blood groups from evolutionary point of view? Is it possable to splice human DNA with an animal of some kind and birth some living hybrid creature? Considering chimpanzees and humans share 90% of the same DNA, why can't they breed together? What happens when DNA structure is changed? What percentage of human DNA is shared with other things? Who coded our DNA? What is the relationship between genes and DNA? Why was DNA chosen to be the genetic material instead of RNA? Do any non-living things contain DNA? What is the point of DNA replication? Does DNA change when growing up from baby to adult? Why is DNA replication imperfect? Will a human and his/her clone have the same fingerprints? What are some unique characteristics of DNA? What is the relation between genes and DNA? Why shouldn't scientists clone human beings? Why is the structure of DNA important? Genetics and Heredity: At what stage of cell cycle do the homologous chromosomes come together? What happens when both parents have the same blood group? How can social behaviour contribute in DNA modifications? What is the importance of DNA copying in reproduction? And another question in details. How do organisms evolve different numbers of chromosomes? How do our genes influence us? Can two different people from different countries with different cultures have same the fingerprint or DNA? Does grandchildren/grandparents relationship exist in any other living beings than humans? Why is the DNA structure a double helix? Why is the DNA structure a double helix?
