Which of the following is a true statement? Species with nucleotide sequences that match closely share a common ancestor. Adaptation to the environment is not related to the origin of new species. The genetic language of DNA and RNA provides evidence that contradicts evolution of finches and other birds. Molecular biologists have suggested that bacteria are more closely related to eukaryotes than are members of the domain Archaea.

Species with nucleotide sequences that match closely share a common ancestor. It is the true statement.

Explanation:

Every species have their specific nucleotide sequences. We can only say a different species as our ancestors when most of the nucleotide sequence will be matched with our nucleotide sequence. It is as like as DNA fingerprinting where the most matching nucleotide sequence is confirmed as their biological family member.

Species with nucleotide sequence that match closely share a common ancestor.

Explanation:

This is an example of common descent in the evolutionary biology where one species which lived in the earlier time becomes the common ancestor for two or more species that came later during the course of time. When we see the genetic code or sequence of nucleotides from bacteria and archea to the plants and animals we find that there is similarity in the sequences.  This provides an evidence for the universal common descent.

When the sequences of nucleotides is found to be similar in two or more organisms, such nucleotide sequences or gene sequences can be termed as Homologous Genes and these are generated due to speciation i.e. the formation of new species from an existing species. Homologous genes are said to be evolutionary related genes.
