The thymus was known to the ancient Greeks, and its name comes from the Greek word θυμός (thumos),
meaning "anger", or in Ancient Greek, "heart, soul, desire, life",
possibly because of its location in the chest, near where emotions are
subjectively felt;[29] or else the name comes from the herb thyme (also in Greek θύμος or θυμάρι), which became the name for a "warty excrescence", possibly due to its resemblance to a bunch of thyme.[30]
Galen was the first to note that the size of the organ changed over the duration of a person's life.[31]
In the nineteenth century, a condition was identified as status thymicolymphaticus defined by an increase in lymphoid tissue and an enlarged thymus. It was thought to be a cause of sudden infant death syndrome but is now an obsolete term.[32]
The importance of the thymus in the immune system was discovered in 1961 by Jacques Miller,
by surgically removing the thymus from one-day-old mice, and observing
the subsequent deficiency in a lymphocyte population, subsequently named
T cells after the organ of their origin.[33][34]
Until the discovery of its immunological role, the thymus had been
dismissed as a "evolutionary accident", without functional importance.[14]
The role the thymus played in ensuring mature T cells tolerated the
tissues of the body was uncovered in 1962, with the finding that T cells
of a transplanted thymus in mice demonstrated tolerance towards tissues
of the donor mouse.[14]
B cells and T cells were identified as different types of lymphocytes
in 1968, and the fact that T cells required maturation in the thymus was
understood.[14] The subtypes of T cells (CD8 and CD4) were identified by 1975.[14]
The way that these subclasses of T cells matured – positive selection
of cells that functionally bound to MHC receptors – was known by the
1990s.[14]
The important role of the AIRE gene, and the role of negative selection
in preventing autoreactive T cells from maturing, was understood by
1994.[14]
Recently, advances in immunology have allowed the function of the thymus in T-cell maturation to be more fully understood.[14]
Anahata or heart chakra is the fourth primary chakra, according to Hindu Yogic, ... In the endocrine system, Anahata is said to be associated with the thymus ...
Sep 15, 2015 — The thymus
gland, located behind the breast bone, produces T cells which are vital
for immunity, as well as fighting off infections and disease.
The heart chakra is situated in the centre of the chest at the height of the thymus gland (behind the sternum). In Sanskrit this chakra is called Anahata, ...
Anahata (Sanskrit: अनाहत, IAST: Anāhata, English: "unstruck") or heart chakra is the fourth primary chakra, according to HinduYogic, Shakta and Buddhist Tantric traditions. In Sanskrit, anahata means "unhurt, unstruck, and unbeaten". Anahata Nad refers to the Vedic concept of unstruck sound (the sound of the celestial realm). Anahata is associated with balance, calmness, and serenity.
Associations with the body
Anahata is said to be near the heart. Because of its connection to touch (sense) and actions, it is associated with the skin and hands. In the endocrine system, Anahata is said to be associated with the thymus.[citation needed]
In Yogic practices, anahata is awakened and balanced by asanas, pranayamas and the practice of ajapa japa (japa, without the mental effort normally needed to repeat the mantra) and purified by bhakti (devotion).
There are also special Concentration practices for awakening the Anāhata Chakra.[11]

いらないものがないんじゃなくて、いらないかどうかを決めるのは
その生物の生き様と環境ってだけなんすよねwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
だから要らなくなったものは退化していくんでしょwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
普通に考えて人間のみならず生物は全て永久に進化の途上でしょうよwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
別に科学が未熟なのではなく、本来の科学の立場を忘れてよく調べもせずに

他人に教えたくないものを教えるわけがない。
他人の知恵を奪うには「教えなきゃウソ」っていう理屈を建てればいいい
それでも教えないあるいは本人にしかできないことなら殺してしまえ
なんてこと考える人達がいたら嫌ですね。

脳の能の仕組み心臓がなぜ動くか結局わかりきってるものなんかないのに
権威とかぬかして否定を断定するのがどうかしてるんだよね
ま、そうさせたのは保険という仕組みでもあるんだけど
