To investigate the evolutionary relationships between a reference mammal (Species XXX) and four other modern mammalian species (WWW, YYY, ZZZ, and VVV), scientists raised antibodies against the serum albumin of Species XXX. These antibodies were then mixed with equal concentrations of serum albumin from species WWW, YYY, ZZZ, and VVV. The percentage of precipitate formed in each mixture was recorded:
| Species | Percentage of precipitate formed (%) |
|---|---|
| WWW | 35 |
| YYY | 82 |
| ZZZ | 14 |
| VVV | 63 |
Which of the following sequences correctly ranks the species from the one sharing the most recent common ancestor with Species X X\,X to the one sharing the most ancient common ancestor with Species XXX?
Z→W→V→YZ \rightarrow W \rightarrow V \rightarrow YZ→W→V→Y
Y→W→V→ZY \rightarrow W \rightarrow V \rightarrow ZY→W→V→Z
Y→V→W→ZY \rightarrow V \rightarrow W \rightarrow ZY→V→W→Z
Z→V→W→YZ \rightarrow V \rightarrow W \rightarrow YZ→V→W→Y
