When two groups of organisms independently evolve similar adaptations, it’s called convergent evolution. Sharks and whales both have streamlined bodies and tail flukes. How do we know that these similarities are because of convergent evolution? Hint: Whales are tetrapods. Are sharks?

These similarities can be studied through evolutionary patterns based on morphological and/or genetic data

Explanation:

Analogous structures such as wings in birds and bats are the product of convergent evolution. Convergent evolution is the process for which analogous structures evolve in species not phylogenetically related

i'll try what topic lol

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
