For an organism, a section of the DNA code reads CAATCT. Over time, two species form from this population. Species 1 has a mutation in this
region; it has CTATCT. Species 2 has another mutation; it has CAATAT.
Scientists discover a new organism, species 3. The new organism has
the code CTATCG for the same section.
Which option is most likely true for species 3?

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

it would be heredity

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
