Why only humans are different than the rest of animals in terms of thinking, talking
and the way of living, no animal can be compared to humans?
Why we can't even see animals in midway between humans and animals in
terms of thinking, talking and the ability to invent ..etc?
How that is explained by science, we can see different kinds of animals horses, donkeys, dogs,
different kind of birds, but why humans are unique?
Humans, Homo sapiens, has resulted from gradual evolution of how humans came about. We may start the progression with the catarrhine Parapithecus (Oligocene, 35 million years ago), Propliopithecus, Aegyptopithecus, Saadanius (29 milllion years ago), Kamoyapithecus (24 million years ago); then the arboreal (tree dwelling catarrhine) in early Miocene with fossil finds in East Africa; the monkey Victoriapithecus (20 million years ago); then Proconsul, Rangwapithecus, Dendropithecus, Limnopithecus, Nacholapithecus, Equatorius, Nyanzapithecus, Afropithecus, Heliopithecus, and Kenyapithecus, fossil finds all in East Africa (13 million years ago); the non-cercopithecids Otavipithecus fossil finds in Namibia; the Pierolapithecus and Dryopithecus fossil finds in France, Spain and Austria (middle Miocene); Oreopithecus fossil finds in Italy (9 million years ago); then the following sequence of transition: Sahelanthropus tchadensis (7 million years ago); Orrorin tugenensis; Ardipithecus ramidus; Australopithecus anamensis; Australopithecus afarensis; Kenyanthropus platyops; Australopithecus africanus; Australopithecus garhi; Australopithecus sediba; Australopithecus aethiopicus; Australopithecus robustus; Australopithecus boisei; Homo habilis; Homo georgicus; Homo erectus; Homo ergaster; Homo antecessor; Homo heidelbergensis; Homo neanderthalensis; Homo floresiensis; and humans Homo sapiens sapiens (today).
One would assume that they were intermediates and went extinct because they were gradually replaced.
