arguments for the waterside models (including the aquatic ape hypothesis)

species : Homo sapiens

proposed natural habitat : coasts & beaches

# Category Hypothesis Status
A Swimming Possible adaptations for floating and swimming on the water surface

A Swimming Reduction of body hair and smooth skin surface evolved for reducing drag.[1] Speculated
A Swimming Dark skin pigment evolved for blocking sunlight in tropical waters.[3] Speculated

A Swimming Fusiform, straight, streamlined body evolved for reducing drag.[1] Speculated
A Swimming Lower bone density evolved for increasing buoyancy (c.f. higher density in Homo erectus possibly evolved for shallow bottom diving).[5] Speculated

B Diving Possible adaptations for apnea diving under water
B Diving Human evolved better diving ability than land mammals, capability lasts from birth to very old ages (e.g. 90).[8] Evidence support
B Diving Human's bimodal diving pattern similar to sea otters: serial short dives to <20m, separated by recovery intervals, in extreme cases down to 100m.[8] Evidence support
B Diving Enhanced diving reflex approaching the level of semi-aquatic mammals:[8]
- Bradycardia: heartbeat reduces during immersion to save oxygen;
- Peripheral vasoconstriction: blood flow to limbs cuts down to save oxygen for important organs;
- Blood shift: blood fills lung vessels and cavities in extreme depth to prevent organs crushed.
Evidence support
B Diving Fewer & larger red blood cells, higher concentration of hemoglobin evolved for better oxygen storage under water.[7] Speculated
B Diving Spleen contracts to release extra red blood cells during prolonged diving.[8] Evidence support
B Diving Fine breath control evolved for diving, later as exadaption for speech:[4][3]
- Descended larynx allows mouth breathing for inhaling more air before dives / during swimming;
- Better voluntary breath control for conscious planning of inhalation;
- Breathing pattern in diving (quick inhale & slow exhale) similar to that in speech.
Speculated
B Diving Ablility to equalize ears at depth as a behavioral adaptation.[8] Evidence support
B Diving Mobile neck evolved for searching resources under water.[6] Speculated
B Diving Flexible backbone enables lift-based "dolphin kick" under water.[4] Speculated
B Diving Dexterous, sensitive hands evolved for collecting and hunting underwater, led to first pebble tool-making and fire-making began near the shore.[1] Speculated
B Diving More efficient countercurrent veins in limbs evolved for reducing heat loss in water.[6] Speculated
B Diving Multi-pyramidal kidneys evolved for excreting excess salt from saline water.[8] Speculated
B Diving High output of water and salt due to abundance of both elements in habitat: abundant sweat & tears, saturated expiration, dilute urine, watery faeces.[7] Speculated
B Diving Sweat (perhaps also tears) evolved for excreting excess salt.[4] Withdrawn

D Infancy Newborns able to hold breath until reaching the water surface.[9] Evidence support
E Sex Possible sexual selection and adaptations in a waterside context
E Sex Facial hair and baldness in males evolved for further streamlining the head and neck during diving (alternative: facial hair evolved as a sexual signal above the water surface).[5] Speculated
E Sex Foreskin in males evolved for avoiding infection in sea water.[6] Speculated

K Scenario Auditory exostosis (surfer's ear) in modern human swimmers and fossils of more recent Homo (H. sapiens, H. neanderthalensis and H. erectus) suggests diving activities.[13] Evidence support
K Scenario Several species of human-specific aquatic parasites (e.g. Dracunculus, Schistosoma) co-evolved with human ancestors.[10] Speculated
K Scenario Aquatic ape model (Hardy/Morgan) - Single semi-aquatic phase in a Miocene "fossil gap" before Australopithecus led to human-chimp split, possibly on an isolated island in East Africa, later returned to land.[1][2] Disproved
K Scenario Saci LCA model (Bender) - Loss of instinctive swimming (i.e. dog paddle) in early hominoids (Miocene apes) due to intense adaptation to arboreal life, led to intrinsic risk of drowning in all extant apes including human.[14] Speculated

- Frugivorous and freshwater diet, collecting food by wading & climbing;
- Partial bipedalism and upright posture aided by buoyancy and/or grasping branches
Speculated
K Scenario Littoral dispersal model (Verhaegen) - Gradual coastal adaptations reached maximum in Homo erectus (Pleistocene) as shallow bottom divers along Indo-Pacific coasts:[8][16]
- Denser bones (pachyosteosclerosis) evolved to aid bottom diving in shallow water to collect sessile foods, causing auditory exostosis;
- Thick back of skull evolved for back-floating between dives.
Speculated
K Scenario Shore-based model - freshwater (Cunnane et al.) - Gradual freshwater adaptations in early hominins (Pliocene):[12]
- Spead along East African coastal forests and riverine corridors - Aridity refugium model (Joordens);[17]
- Freshwater diet enabled moderate levels of brain expansion;
- Thicker enamel, polished molars in Australopithecus due to eating tough aquatic plants (e.g. papyrus sedge); may also ate catfish;
- Thicker enamel, large molars, heavy skull in Paranthropus evolved for eating hard-shelled invertebrates, comparable to otters;
- Thinner enamel in early Homo (e.g. Homo habilis) due to more reliance on stone tools.
Evidence support
K Scenario Shore-based model - coastal (Cunnane et al.) - Gradual coastal adaptations in Homo (Pleistocene):[12]
- Hunting fish and collecting shellfish using advanced technologies (e.g. spears, nets);
- Seafaring to islands, e.g. Homo erectus to Crete, Homo neanderthalensis to Flores, Homo sapiens to Australia;
- Marine diet enabled further brain expansion;
- Behavioral modernity in Homo sapiens first emerged in South Africa coasts, with intense exploitation of coastal resources.[18]
Evidence support
K Scenario Coastal migration model - Homo sapiens migrated along Indo-Pacific coasts from Africa down to South America:[19][20]
- Hopping among estuaries[21], islands and possibly kelp forests[22], travelling by boats and/or swimming (Pleistocene);
- Later more humans settled along rivers and inland habitats with the advance of agriculture (Holocene).
