How Has Biodiversity Has Changed Over Time?

Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part of, this includes diversity within species, between species, and of ecosystems. Biodiversity in animals have changed over time whether it has been through genetics or adaptations from outside forces, such as ecosystems. The question that has been through multiple assumptions and have been approached many times is: How has biodiversity on Earth changed over time? The question has opened many gates to many different answers, but what does it actually mean? This statement explains how organisms have grown and made adaptations throughout their ecosystems in order
In relation to richness in different life forms, Earth consists of about, or more than, 1.5 million different types of life forms. This proves the hypothesis of, “How present day forms of life arose from other forms of life over a considerable amount of time. As a result, biodiversity has increased throughout Earth’s history.” Another evidentiary fact is the “Lab22DiversityInTheFossilRecordData.xlsx,” which explains, and demonstrates different organisms that were discovered, and were given an estimated time they were living. A family by the name of “Tachyglossidae,” has been logged in the fossil record as supposedly living from seven million years ago, and last seen 100 years ago, were it had credibly been assumed as extinct. An organism that belongs to this family is the Echidnas, also known as spiny anteaters. They are also in the monotreme order of egg-laying mammals. The fossil record concludes that species like the Echidnas were once alive. Thus concludes an assumption that because of external forces, such as environment, have made an impact of the survival of this
