Question

What would a fossil record of life today look like?

Short answer

The fossil record of today’s life possesses the hard body organs of many living organisms, including marine invertebrates and all vertebrates.

The fossil record of today would also include shells, exoskeleton, and impression of microorganisms and animals but might not contain some species, including small population sizes or small geographic ranges.

Step-by-step solution

Fossil record

A fossil is a shred of significant evidence for evolution depicting the life on the planet. The fossil record provides valuable content of living things involving many events where new species are evolved spontaneously embedded in stratified geologic rocks. The totality of fossils, the evolution of organisms, and their extinctions are shown in the fossil record.

Arthropods and tetrapods

The first animals to colonize land were invertebrate animals, including arthropodsthat covered almost all of the habitats in the terrestrial environment.Tetrapods, including humans and arthropods, are the most diverse and extensive species of terrestrial habitat.

The ancestors of humans diverged from other primates approximately 6 million years ago. At the same time, the earliest tetrapods were present in the fossil record and evolved from a group of lobe-finned fishes.

Earliest multicellular eukaryotes

The earliest multicellular eukaryotes body fossil is the multicellular algae that lived 1.2 billion years ago. The multicellular eukaryotes may be small, dating to 1.8 billion years ago, while larger multicellular eukaryotes are not found in the fossil record until before six hundred million years.

A fossil record of today’s existence may include hard shells, hard body parts, and an exoskeleton made of calcium of many living organisms.
