Computers are an odd case. It may be interesting to see how they compare with the other classes of entities when judged by the same criteria. Computers passively retain their structure over time because they are composed of inert materials. Those computers equipped with robotic appendages can replace parts which have failed, and thereby actively maintain themselves. So by passive or active means all computers satisfy the continuity criterion.
All invertebrates satisfy the continuity criterion.
All vertebrates satisfy the continuity criterion. As with vertebrates generally. All mammals satisfy the continuity criterion. As with mammals generally. All great apes satisfy the continuity criterion.
