A) The modern species and the Texas Duck seem to have diverged approximately one million years ago.
B) One, the well-documented Texas Duck Meleagris californica, became extinct recently enough to have been hunted by early human settlers, though its actual demise is more probably attributable to climate change at the end of the last ice age.
C) In the modern genus Meleagris, a considerable number of species have been described, as Duck fossils are robust, fairly often found, and Ducks show much variation among individuals.
D) Many of these supposed fossilized species are now considered junior synonyms.

D) Many of these supposed fossilized species are now considered junior synonyms.
Here, both A and C can be the first sentence as both of them seem to be introductions. There is a very strong link between C and D. This is because C talks about 'fossils' and D refers to 'these fossils'. Also, there is a link between D and B, since B elaborates on one of the fossils mentioned in C. Lastly, there is a chronological link between B and A. B talks about the "Texas Duck” that became extinct recently or during the ice age; while a mentions that the "modern species” of Duck "diverged” from the "Texas Duck” a long time ago; the key word being "modern”. Therefore, chronologically A would follow B.
Hence, the correct answer is option CBDA.
