1. This raises a potential challenge to biblical creation:

As we discover more fossils, there may be further challenges in kind. One issue this raises is whether Christians should just admit that human evolution is true. Is the time past due to throw in the towel? Sure, we can contrive ingenuous explanations to reconcile this with biblical creation, but isn't that special pleading? It's only because Genesis is part of the sacred canon of Christianity rather than The Argonautica that we make an effort to defend the historicity of Genesis when we'd never make a comparable effort to defend the historicity of The Argonautica. So goes the argument. 

It would, indeed be special pleading to defend the historicity of The Argonautica, but the comparison is inapt. If there's abundant evidence that Christianity is true, then it's not special pleading to treat the Bible differently than we treat The Argonautica. 

Not to mention that there are scientific objections to the theory of evolution. The evidence isn't one-sided. 

2. Another issue is how we tell that something has humanoid intelligence. For instance, there are animals that use things designed by humans. It would be invalid to infer that animals invent what they use. For that matter, lots of humans are smart enough to use a cellphone who aren't smart enough to design a cellphone. So there's a distinction between inventing tools and using tools. Suppose you had jungle inhabited by humans and apes. Apes might steal human tools and toy with them. Discovering apes with tools wouldn't ipso facto prove the apes had humanoid intelligence. 

3. There's also the question of how we identify humanoid intelligence. This goes to the larger issue of what makes humans human or unique compared to animals. A common criterion is a certain level of intelligence. A capacity for abstract thought. Imagination. Deliberation. Thinking about the past and future. Is it possible for a creature to have humanoid intelligence, yet be inhuman?

In Christian theology, angels have humanoid intelligence, yet angels are unrelated to humans. To take another example, there's a sense in which psychopaths are both human and inhuman. On the one hand they have human intelligence. Indeed, above-average intelligence. Yet a psychopath lacks normal human psychology. Psychos are expert at mimicking human emotions, but they lack human emotions. In particular, they lack empathy. They have no conscience. 

A psychopath is like a vampire. A vampire retains human intelligence and memories. But its psychological makeup is inhuman. When it looks at a human being, it views the human as food. By the same token, psychos are predators who hunt human prey. So there's something fundamentally inhuman about psychopaths (and sociopaths). 

Or take someone like Bobby Fischer who's a genius, but devoid of social intelligence. He can relate to the game of chess, but he can't relate to human beings. 

Or, to consider this from the other end of the telescope, consider people with Down syndrome who, in a sense, have subhuman intelligence, yet they have a human emotional makeup. In a sense, someone with Down syndrome has greater humanity than Bobby Fischer. 

Another example, albeit fictional, is rational aliens. Suppose you had a conversation with an E.T. Initially, you might find that you have a lot in common with the E.T. But as the conversation progresses, you come to the terrifying realization that there's something fundamentally foreign about its outlook. Suppose what humans find beautiful, our hypothetical aliens don't find beautiful. What we find emotionally compelling, they don't. They don't respond to music. They don't gaze in awe at sunsets. They have no instinct to comfort a crying child. 

4. Apropos (3), imagine if God created some animals with humanoid intelligence that are, nevertheless, unrelated to humans. Imagine if you had a conversation with one of them. At first you seem to share a lot in common. But as the conversation deepens, it becomes increasingly apparent that they operate on a different wavelength. Humanoid intelligence is, at best, a necessary but insufficient condition to make one human. And even that may be overstated (e.g. Down syndrome). 

5. Scripture doesn't detail the animals God created. It classifies them by ecological zone. Land animals, aquatic animals, and volant animals. Even if God created (now extinct) animals with humanoid intelligence, there's no presumption that Scripture would mention that fact. Just as there's no expectation that the Genesis narrator would list the Tasmanian devil. For one thing, the original audience would have no idea what the narrator was referring to. Indeed, the narrator wouldn't have the vocabulary. And even if the Bible did use the word "Tasmanian devil", that term would be co-opted by Bible readers to refer to something other than the marsupial. By the time the Tasmania devil was discovered, it would be called something else.

6. Inspiration doesn't make a Bible writer omniscient. The Genesis narrator was ignorant about the existence of most species. But ignorance is not the same thing as error. And even if he knew about Australian/Tasmanian fauna, there'd be no occasion to mention that in the creation account. By the same token, even if God created (now extinct) animals with humanoid intelligence, there'd be no reason for Genesis to mention that.
