Genesis 2:19-20 tells the story of Adam’s task:
"Now the Lord God had formed out of the ground all the wild animals and all the birds in the sky. He brought them to the man to see what he would name them; and whatever the man called each living creature, that was its name. So the man gave names to all the livestock, the birds in the sky and all the wild animals."
If you’re a believer in the literal truth of the Bible, you should be interested to know about the recent work of Camilo Mora and colleagues. The 2011 journal “How Many Species Are There on Earth and in the Ocean?” (Mora C, Tittensor DP, Adl S, Simpson AGB, Worm B. PLoS Biol 9(8): e1001127. doi:10.1371/journal.pbio.1001127) uses taxonomic estimation to determine that there are 7.77 million species of animals on planet Earth:
If the Lord God brought all the wild animals to Adam to be named, all 7.7 million of them, then Adam must have been at it for quite a while. If Adam got up each and every day at 6 AM, and named a new animal every 2 seconds (try saying “Thompson’s Gazelle” in less than two seconds), not stopping until 6 PM every night, then Adam would have been at it for an entire year.
The need for speed would explain “Bonobo.”
