William Branham claimed that he had been a game warden. If that's true, he really did not understand biology.
What we know is true
Calling anything a "lower" or "higher" form of life is a purely subjective value judgment that doesn't exist in nature. However, looking at simple life forms, the archaea constitute a kingdom of single-celled microorganisms. These microbes have no cell nucleus or any other membrane-bound organelles in their cells.
Opinions differ on whether viruses are a form of life, or are organic structures that interact with living organisms. They have been described as "organisms at the edge of life", since they resemble organisms in that they possess genes and evolve by natural selection, and reproduce by creating multiple copies of themselves through self-assembly. Although they have genes, they do not have a cellular structure, which is often seen as the basic unit of life. Viruses do not have their own metabolism, and require a host cell to make new products. They therefore cannot naturally reproduce outside a host cell. Accepted forms of life use cell division to reproduce, whereas viruses spontaneously assemble within cells. They differ from autonomous growth of crystals as they inherit genetic mutations while being subject to natural selection.
Quotes of William Branham
Now, watch. What's the lowest form of life we have? Frog. What's the highest form of life? Human. Certainly. And what is the highest form? It just kept coming from the lowest on up, from a frog to this and to that, and to the bird, and to, oh, so forth, just higher forms of life, until it come to the highest form it could come, then it was made in the image of God. There you are. And the woman was not made in the image of God, but in the image of man.
The lowest form of life that there is the frog. The highest form is the human being. God started at the bottom and made right up till He brought it plumb to His image. Brought it from the birds and the beasts and on up till He got to the image of God. He made man in that image; that's the highest form. The lowest form is just a polliwog that turned into a frog and so forth.
Do you know what kind of an animal always looks back? The lowest life there is. How many knows what the lowest life there is that moves? A frog. A frog is the lowest life there is, and a man is the highest life there is. And a frog looks backwards. I don't like that old low life. I want to look forward, believing, trusting, walking in the Light as He is in the Light, amen, as He shines the Light.
