As a biodiversity expert with a background in ecology and conservation biology, I have a deep understanding of the complex dynamics that influence the variety of life on Earth. The biodiversity of our planet has undergone significant changes over geological time, shaped by various factors including natural processes and, more recently, human activities.
Step 1: English Answer
The biodiversity of Earth has been influenced by a multitude of factors throughout its history.
Speciation, the process by which new species evolve, and extinction, the loss of species, are two critical evolutionary processes that have been at play. These processes operate in a delicate balance, with the rate of new species formation often counterbalanced by the rate of species loss.
Throughout Earth's history, there have been five major mass extinctions, each resulting in a significant and rapid decline in biodiversity. These events were often triggered by catastrophic changes to the environment, such as volcanic eruptions, asteroid impacts, or rapid climate change. For example, the Permian-Triassic extinction event, also known as the "Great Dying," occurred around 252 million years ago and led to the extinction of approximately 90% of marine species and 70% of terrestrial species.
Between these mass extinctions, periods of recovery and diversification allowed biodiversity to rebound and even flourish. The **Cretaceous-Paleogene (K-Pg) extinction event**, which occurred around 66 million years ago and wiped out the dinosaurs, was followed by the rise of mammals and the eventual evolution of humans.
In more recent times, the Anthropocene epoch, marked by significant human impact on the environment, has led to what many scientists consider the sixth mass extinction event. Human activities such as deforestation, pollution, overfishing, and the introduction of invasive species have accelerated the rate of species loss. Climate change, driven by the burning of fossil fuels and deforestation, is also a significant factor, altering habitats and leading to shifts in species distributions.
The **Intergovernmental Panel on Climate Change (IPCC)** has reported that climate change is causing a wide range of impacts on biodiversity and ecosystems, including changes in the timing of seasonal events, changes in the distribution of species, and increases in the frequency of extreme weather events, which can lead to population declines and extinctions.
Conservation efforts have been implemented to mitigate these losses, including the establishment of protected areas, efforts to reduce carbon emissions, and international agreements such as the Convention on Biological Diversity. These efforts aim to preserve habitats, protect endangered species, and promote sustainable use of resources.
However, the future of biodiversity remains uncertain. Continued efforts are necessary to understand and address the complex challenges facing our planet's ecosystems. The biodiversity crisis is a global issue that requires international cooperation, scientific research, and policy changes to ensure the preservation of Earth's rich tapestry of life.

Biodiversity Change through Geological Time. The number of species on the planet, or in any geographical area, is the result of an equilibrium of two evolutionary processes that are ongoing: speciation and extinction. ... Sudden and dramatic losses of biodiversity, called mass extinctions, have occurred five times.
