This new discovery is nothing to be surprised about. Evolutionists will always have their obsession with everything that looks remotely human, and will always apply to the latest find the time-honored fallacy that because A looks like B, they must be related.
I could also point out the following:
– Pope St. Pius X, Lamentabili Sane
While I do not rule out the idea that honest inquiry into the concept of evolution is possible, it is clear from the above quote that we, as Catholics, have to be extremely careful about how we treat the matter internally. If we truly believe evolution to be a teaching that has been at least implicitly held by Christians from the beginning and is not in any way harmful to faith and morals, we should be able to hold to it until it has been formally condemned.
However, if we believe evolution is something that the Church should adopt simply because the modern world finds it popular, or because we think science can inform theology, we are quite officially modernists, and should promptly stop calling ourselves Catholics.
The Church cannot, will not, and must not change Her doctrines for any reason. If evolution is ultimately proved by the Magisterium to be contrary to the deposit of faith, we will all be obliged to submit and should rejoice that the truth has been proclaimed. Until that day comes (and I hope it will come soon), evolution is something we can, for now, technically believe in, regardless of how much evidence it has against it or how some of us may feel about the matter.
