This page assumes that Weena is representative of an average Eloi. For an opposing view, see the fanon pages (general and more specific to Weena).
The evolutionary changes between present-day humans and the Eloi involve a combination of neoteny, progenesis,[1] and insular dwarfism.[2] Neoteny would be selected for first, while humans still have [reasonably] advanced [medical and sanitation?] technology.[3] Progenesis would be selected for later, by dietary limitations (see below) and the need for a higher reproductive rate to compensate for deaths caused by the Morlocks.
TODO: Explain r/K selection theory and the transition from K-selection in present-day humans to r-selection in the Eloi. r-selection is consistent with the small body size of the Eloi.
This section requires expansion
TODO: Mention this BBC News article
Chapter 4 states that the Eloi are fruitarian:
Such a diet would be poor in vitamin D. This may explain why the Eloi are light-skinned despite living in sunny areas. (However, their skin must not be so light as to create a significant risk of sunburn.[4])
The low caloric content of the Eloi diet suggests that the Eloi have slower metabolisms than similarly sized present-day humans. This may be achieved by decreased thyroid activity, which is consistent with neoteny and/or[clarify] progenesis. The iodine content of the Eloi diet is not precisely known. The Eloi diet appears to lack oceanic sources of iodine, but the iodine content of typical soils is unknown. Nor is it practical to speculate on the genes controlling iodine metabolism in the Eloi thyroid. TODO: In present-day humans, iodine deficiency can cause mental retardation. To what extent would brain function be altered as human descendants evolve to tolerate reduced iodine intake? What about the lack of visible goiter?
TODO: Look at sources relevant to "The short stature of pygmies may be in part an adaptation to conserve vitamin D in the low-UV rainforest environment." (I am aware that the environment observed by the Traveller did not have a lot of tree cover to block the UV rays.)
TODO: Also see what we can pull from answers to CrazySlayaNinjaBear's question about physiology of herbivore-adapted humans.
TODO: Consider possibility of pulmonary edema and renal failure following Weena's drowning incident
TODO: How is obligate nasal breathing relevant? It depends on the details of the developmental cycle.
In chapter 4, the Time Traveller compares his own voice volume and modal pitch to those of the Eloi:
Compared to adult present-day humans, the Eloi have less-developed vocal ligaments, softer laryngeal cartilages, and smaller overall dimensions of the respiratory tract. This relates to the developmental differences mentioned above.
TODO: More quotes
The Eloi have poor cardiovascular fitness due to their lack of regular physical exercise. The Time Traveller observes this (Ch. 4):
TODO: More quotes
The acute stress reaction in the Eloi is poorly controlled and carries a significant risk of vasovagal syncope or more serious heart rhythm disruptions. This may explain Weena's collapse in chapter 9.
TODO: Quotes for the above
In chapter 4, the Traveller makes several observations about Eloi behavior. For instance, the Eloi appear to be limited in overall intelligence: (TODO: Clarify how the interpretation of this quote is necessarily subjective)
Also, the Eloi exhibit symptoms of attention deficit disorder (a.k.a. ADHD predominantly inattentive):
Eloi society is based substantially on the fission-fusion pattern. TODO: Continue explaining/clean up
Fission: Ch. 7: "we went down into the wood ... We soon met others of the dainty ones, laughing and dancing in the sunlight as though there was no such thing in nature as the night."
Fusion: Ch. 5: "...these little people gathered into the great houses after dark, and slept in droves."
