"Other apes can also be taught these same concepts - to a more limited degree , sure , but then the related parts of their brain are smaller and less capable ."
"Yes Peeling ; you say this with such assurance , yet what you ca n't explain with any assurance is why only one offshoot of the Primate genus evolved into what human beings are today . Why only us , when we all allegedly started in the same environment with the same ecosystems putting the same pressures on us . What I 'm saying is that in every place where our alleged primate ancestors fossils have been found , so have n't the fossils of animals described as lower primates been found . So your explanation that one species evolved while another stagnated or died out rings hollow with me . Especially since you can actually prove absolutely none of this . Ca n't you see that Peeling ? None of this is provable ."
