Fossils are the remains or traces of a pre-historic plant or animal. The word " fossil " comes from a Latin word " fossil is" which means "dug up"

化石是史前植物或动物残骸或遗迹，化石这一名词来自于拉丁文fossilis，意思是挖掘。

Darwin discussed about some anomalous forms in fresh water basins, which belong to the remnants of some interesting orders. Because these anomalous forms exhibit the anomaly of geographical distribution e.g. Ganoid fishes, or morphological anomaly such as Ornithorhynchus and Lepidosiren , they may be called living fossils. It is believed that Darwin presented the facts of the above anomalous forms, and used the term "living fossil" in order to further illustrate the subject of "Circumstances Favorable for the Production of New Forms Through Natural Selection" in Chapter IV. The term "living fossil" appears on page 486 again in the last Chapter, i.e. Chapter XIV "Recapitulation and Conclusion", where Darwin emphasized the significance of so-called "living fossils".

The results were as follows. In the insert mutation genotypes, there was significant difference between body weights of 2 weeks aged BB and AB genotype (P.05), while there was no significant difference between AA and other genotypes. In the mutation genotypes, there was no significant difference in body weight. Insert mutation loci had no significant effect on fossil bone length and shank length of 0-12 weeks aged chickens, only mutation loci had a significant effect on fossil bone length and shank length of 6 weeks aged chickens.
