Answer:
According to evolutionary biologists, this great diversity did not exist early on the earth. It has taken millions of years to accumulate such diversity on earth. 3. Diversification comes as a result of ever changing environmental conditions which are either introduced by man or nature itself.

Explanation:
- Diversification results from constantly changing environmental conditions that may be brought about by man or by nature.
- The need to alter oneself in order to better adapt to changing circumstances arises.
- Scientists at the Museum have discovered that the trend for species variety to be greatest towards the equator developed 34 to 48 million years ago during the Eocene Epoch.
- Ecological life support: Biodiversity creates healthy ecosystems that produce oxygen, clean air and water, pollinate plants, control pests, process sewage, and perform a variety of other ecosystem services.
- Recreation—many leisure activities, including birdwatching, hiking, camping, and fishing, depend on our distinctive biodiversity.
- Humans are dependent on biodiversity for a variety of reasons, including the foods we consume, the medications we take to stay healthy, and the materials we use to build or clothe ourselves.
- These services are the material goods or things that both our species and other animals need to survive.
