Heartbeats of Zebrafish Mystify Evolutionists
As discussed on several occasions, biblical creationists use irreducible complexity arguments. These have been in use before Michael Behe coined the term. It essentially means that all the parts in certain organisms or devices must be in place at the same time or nothing makes sense.
Zebrafish are a favorite of aquarists, and scientists like using them for study. Interesting new research startled some believers in descent with modifications evolution. A form of irreducible complexity was seen, but it happened in a different way!

Harvard University Professors Bloomekat and Chi’s zebrafish research concluded that the “heart cells in zebrafish start beating suddenly and all at once to form a synchronized heartbeat.” When zebrafish hearts are developed, only 24 hours after it hatches, each cell can beat on its own. Cell beating would not be selected by natural selection until the heart and circulatory system existed and were already functioning. As the authors say, “the first heartbeat occurs even before formation of the primitive heart tube (the first functional structure formed during heart development).”
