A challenge to traditional (pre-1860) ideas about species came from embryology, when it was discovered that embryos of dissimilar organisms, such as sharks and humans, resemble each other. Embryology involves the study of the formation and the development of an embryo and the fetus. It is one type of evidence of evolution such that the embryos of many different kinds of animals, mammals, reptiles, birds, fish among others, are similar showing a common ancestry.

Answer:
BRCA1 and BRCA2 genes
Explanation:
The BRCA1 and BRCA2 genes are tumor suppressor genes that encode breast cancer susceptibility proteins involved in repairing double-strand DNA breaks (DSBs) by the mechanism of homologous recombination. This mechanism uses the sister chromatid of the homologous chromosome as template for repairing DSBs. It has been shown that mutations in BRCA1 and BRCA2 genes alter the molecular mechanism of homologous recombination DNA repair, thereby mutations are not repaired appropriately and persist in the DNA of tumor cells.
