Why are men and women different?

 }Scientists believe they have now uncovered the reason for this difference between the sexes they make the memories in different ways.

}Males use different genes from females when making the new connections in the brain that are needed tthis might explain why men are far better at remembering "tactical" memories, such as travel directions and trivia, while women form more "emotional" memories such as birthdays, wedding anniversaries and details about the world around them.o create long-term memories. 

Genetic and Mutation

 }Genetic: is the study of genes, and tries to explain what they are and how they work. 

}Mutations:  is any change in the sequence of the DNA encoding a gene.

How genetic mutations drive evolution?

}Genetic mutations, which can cause new biological traits, happen randomly and occur continuously.

}Mutations are the raw materials of evolution. Evolution absolutely depends on mutations because this is the only way that new alleles and new regulatory regions are created.
