Kurt Wise has a short list in "The Creation Hypothesis":

"...the following are the steps (with the radiometric time of first
appearance of each step in parentheses, in millions of years before
the present) bacteria (3500); protists (1500-1800); invertebrate
animals (590-570), jawless fish (517-510), jawed fish (424-409), bony
lobe-finned fish (408), amphibians (377-363), reptiles (323-311),
mammals (210-208), primates (70-65), apes (22), hominid (5.5), Homo
(1.8?-1.6), H. sapiens (0.1), art (0.05) civilization (0.01)." (Wise
K.P., "The Origin of Life's Major Groups", in Moreland J.P. ed.,
"The Creation Hypothesis", InterVarsity Press: Downers Grove Ill.,
1994, pp224-225)

Kurt has references to the source materials which I have removed
because his reference numbers were in superscript which in straight
text mode would be confused with the dates. If you need the references,
email me privately.
