Izwe likamoya likhona kuphela emphakathini wesintu. Ingabe izilwane zinezwe likamoya? Ukuhlola kubonisa ukuthi izilwane eziphakeme, njengama-primates nama-cetaceans, zinezinga eliphezulu lemisebenzi ye-neural, zingakwazi ukufunda futhi zikhumbule, futhi zibe nemizwa yothando nenzondo, kodwa ngemva kwakho konke, ziphansi kakhulu kunabantu futhi azanele ukwenza umhlaba kamoya ophelele. Umhlaba kamoya uwuhlobo oluthile lokuvezwa kwezwe elibonakalayo kanye nendlela yokuphila ethuthukisiwe. Isayensi yebhayoloji nobuchwepheshe wuhlelo lwethiyori kanye nobuchwepheshe bendlela yokufunda umhlaba wempilo. Kuwukuqonda komuntu ngendlela ehlelekile umhlaba wempilo. Njengoba umhlaba kamoya uwuhlobo oluthuthukisiwe lokunyakaza kwempilo, zonke izimpumelelo zempucuko engokomoya nakanjani zizobandakanya umqondo wempilo futhi zihlolwe isayensi yezinto eziphilayo. Ngakho-ke, isayensi yokuphila iyisisekelo esibalulekile sokwakheka kwamagugu esayensi.
