Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
true
we will take cows as an example, they inhabit earth and so do we as humans. we as humans put the on our farms and our grass lands. we give the cows a biome. so that makes the statement true.
tell me if I am wrong. :)
