For evolution to occur:
There must be genetic variation in a population. This provides variation on which natural selection can act. Then natural selection can act by selecting those species which are better adapted to the environmental conditions. Over time those animals that are best suited to the environment only will survive and reproduce. Those organisms successful genes will be preserved and eventually the gene frequency in the population will change, changing the overall characteristics of a population. This is how evolution occurs.
The original roots of dodder usually die. As a parasitic plant that cannot produce its own chlorophyll, it breaks away from its root system as the roots has no apparent root cap nor apical meristems. Hence the "root" is not performing its very function of water and nutrient uptake. It then produces haustoria, a root-shaped fungi which penetrates host plant which makes the dodder parasitic.
Then they would go extinct
we would not be able to eat them anymore
and the food chain will get messed up because some animals eat the large mouth bass and now they cant, and also the animals that the large mouth bass eats will overpopulate because the large mouth bass isn't there to eat them

In the first stages of Alzheimer’s disease, the patient
affected may experience symptoms, such as memory loss of certain events. As the
time passes, the patient may experience long-term memory loses, the patient may
also revert into being a child. Patients who has been diagnose with Alzheimer’s
Disease are commonly diagnosis with pneumonia, which may lead to their death.
