Sex plays a crucial role in evolution as it allows for genetic diversity through the combination of genetic material from two individuals. This genetic diversity increases the chances of adaptation to changing environmental conditions, which is essential for the survival of a species. Additionally, sexual selection can drive the evolution of traits that improve an individual's ability to compete for mates and reproduce.
In the past century there will be a different classification of human evolution
Sex chromosomes play a crucial role in meiosis by determining the genetic sex of an individual. During meiosis, sex chromosomes pair up and exchange genetic material, leading to the creation of gametes with a unique combination of genetic information. This process ensures genetic diversity and the transmission of sex-linked traits from one generation to the next.
After sex, hormones like oxytocin and prolactin are released in the body. Oxytocin helps with bonding and relaxation, while prolactin promotes feelings of satisfaction and reduces sexual arousal. These hormones play a key role in the body's physiological response after sex.
Sex-limited genes are genes that are only expressed in one sex, leading to the development of specific traits or characteristics unique to that sex. These genes play a crucial role in determining gender-specific features, such as reproductive organs or secondary sexual characteristics, in organisms.
Genes play a critical role in evolution by influencing an organism's traits and characteristics. Changes in genes over generations (mutations, genetic drift, etc.) can lead to new variations that may be advantageous in certain environments, thus driving evolution. The environment also plays a significant role by selecting for certain traits that enhance an organism's survival and reproduction, shaping the direction of evolution.

Natural selection is the changing of organisms gradually over time. Natural selection and evolution are parts of environmental science due to them being the studies of organisms.
