According to Alfred Russel Wallace, disadvantageous traits are eliminated from the population by natural selection. This is the process of evolution as only the dominant individuals are able to reproduce successfully and their traits passed down generations.
However, today in the advent of improved technology in healthcare, more and more ‘disadvantageous traits’ are being maintained in the population due to advances in medicine that improve the survivability of these individuals – such as people with genetic disease like Parkinson’s.

Herbivores are primary consumers. Herbivores eat producers who produce food through photosynthesis. Secondary consumers are carnivores who eat primary consumers (herbivores)
The three evidence that support the existence of plants on Antarctica are:
- Climate;
- Pollen;
- Herbivorous animals;
Apart from the plant fossils found on Antarctica, there are few other evidence that suggest that plants existed in the past on the now frozen continent. Some of those evidence for the existence of plants on Antarctica are the pollen found in the rocks and fossils of organisms, the climate records, as well as the herbivorous animals.
The pollen is only released by the plants, thus that is a sure indicator that plants were occupying this part of the world.
The climate records on Antarctica that can be seen in the rock layers, suggest that for most of its existence, Antarctica had a warm and wet climate, which is perfect conditions for the plants to thrive.
The herbivorous animals are feeding themselves on plant material, so since there's fossils of herbivores in Antarctica, it for sure is an evidence that there were plants existing in order for them to feed and be able to live in there.
