45وَاللَّهُ خَلَقَ كُلَّ دابَّةٍ مِن ماءٍ ۖ فَمِنهُم مَن يَمشي عَلىٰ بَطنِهِ وَمِنهُم مَن يَمشي عَلىٰ رِجلَينِ وَمِنهُم مَن يَمشي عَلىٰ أَربَعٍ ۚ يَخلُقُ اللَّهُ ما يَشاءُ ۚ إِنَّ اللَّهَ عَلىٰ كُلِّ شَيءٍ قَديرٌ(Irfan-ul-Quran)And Allah has originated (chemical genesis of) every moving creature from water. So, some of them creep on their bellies, some walk on two feet and some others on four. Allah creates what He wills. Surely Allah has Absolute Power over everything.
