Due to billions of years of evolution, humans share genes with all living organisms. The percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us.

Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree. Besides similarities in anatomy and behavior, our close biological kinship with other primate species is indicated by DNA evidence. It confirms that our closest living biological relatives are chimpanzees and bonobos, with whom we share many traits. But we did not evolve directly from any primates living today.

DNA also shows that our species and chimpanzees diverged from a common ancestor species that lived between 8 and 6 million years ago. The last common ancestor of monkeys and apes lived about 25 million years ago.

Once they have penetrated the first line of defense, which microorganisms do natural killer (nk) cells actively attack?
stellarik [79]

Once they have penetrated the first line of defense, NK cells are the principal defenders against only tumor cells or virally infected cells.

<h3>What are NK cells?</h3>

A particular class of immune cell that contains granules, or tiny particles, that contain enzymes that can destroy cancer cells or virus-infected cells. White blood cells, or NK cells, are one type of them. known as NK-LGL and natural killer cell, respectively.

Natural killer (NK) cells are effector lymphocytes of the innate immune system that regulate various tumour types and bacterial infections by preventing their growth and subsequent tissue damage.

Human NK cells are created from hematopoietic stem cells (HSCs), and as they transition from being CD56high to CD56low, KIRs, CD57, and NKG2C are expressed on terminally differentiated NK cells. During this time, NKG2A is gradually lost.
