Step-by-step explanation:

Answer 2

C) Photosynthetic bacteria, invertebrates, vertebrates, reptiles, amphibians, mammal.

Step-by-step explanation:

• From looking at the above records of evolutionary life on earth the traces of living fossils and organisms that are evolved to the biogenic carbon signatures and the earliest known stromatolite fossils on earth the evidence of 3.7 billion year rocks taken from western Greenland.

• All show the occurrence of first life forms as photosynthetic bacteria and evolution of soil and oxygen in it took place then the invertebrates plat and animals appeared on land and oceans like the nematodes and arthropods, after which started to evolve like the vertebrates like the tetrapod the first fish with four limbs in 360 million years.

• After which reptiles and dinosaurs are the largest land reptiles evolved and then came the amphibian likes and then lead to the evolution of man and other mammals.
