New Defender's Study Bible Notes
1:25 after his kind. The phrase “after his kind” occurs repeatedly, stressing the reproductive integrity of each land animal kind, of the same sort as that of each plant kind (Genesis 1:11-12) and each air animal and water animal (Genesis 1:21). All of these reproductive systems are programmed in terms of the biochemical genetic code, utilizing the basic elements of the earth. Both plants and animals are formed from the created eretz (“earth”), only animals from the created nephesh (“soul” or consciousness).
