Mankind
The culmination of this final stage gets a whole lot of important detail: the emergence of homo sapiens.
God said, "Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the birds of the sky, and over the livestock, and over all the earth, and over every creeping thing that creeps on the earth." God created man in his own image. In God's image he created him; male and female he created them. God blessed them. God said to them, "Be fruitful, multiply, fill the earth, and subdue it. Have dominion over the fish of the sea, over the birds of the sky, and over every living thing that moves on the earth." God said, "Behold, I have given you every herb yielding seed, which is on the surface of all the earth, and every tree, which bears fruit yielding seed. It will be your food. To every animal of the earth, and to every bird of the sky, and to everything that creeps on the earth, in which there is life, I have given every green herb for food;" and it was so.
When evolutionary biologists were first thinking about primates, they coined the term 'hominids' to describe remains that had the skeletal appearance of being similar to modern humans. There is still some discussion about various proposed near- human remains, and of course more discoveries may generate more discussion. This is not the place to go into details, and the starting point for the layman would be the phrase 'human evolution' in Wikipedia and other similar sources. The key thing is that today there is a species which is called 'homo sapiens' which is both similar to and distinct from other primates.
What does the Genesis myth tell us about 'homo sapiens'? This is the question that matters, and for many this is what makes the Genesis myth so revealing.
Humans are uniquely possessed of one attribute: they are like God. Their wisdom (sapiens is Latin for wise) makes it possible for them to dominate all other species. Our myth tells us that this is not only a power held but a responsibility given. Their emergence was with a purpose. They are the ecological managers of the planet they live on.
So I suggest this modern retelling:
"Finally humans were given the divine attribute of wisdom, and the responsibility to manage and care for the planet earth and all its living beings. They were given male and female sexuality so that they could populate the whole planet and all the vegetation was to be their sustenance, as it was for the other dry land animals."
