There are 4 evolutionary mechanisms : Natural selection, gene flow,mutations and genetic drift.

In our case, we are talking about the natural selection.

Natural selection is an evolutionary mechanism that favors individuals that are the most fit for their environment. Certain individuals in a population can have a trait that gives them a survival advantage over the other individuals in the population. Natural selection favors these individuals and they leave more offspring and are more successful. In the case of lung fishes, their lungs were a trait that gave them a huge advantage because it enabled them to live outside the water and use new resources available on land.

Name to types of evidence that scientist used to support the theory of evolution?
Sergio [31]
Evidence of evolution. Scientists support the evidence of evolution because of the adaptations organisms used to have in the past compared to the present. For example, humans have organs in their bodies they don't need, but must have been used in ancient times. They can also find that humans have a common ancestor such as monkeys because of the DNA similarities and many adaptations. Hopefully this answered most of your question.

VikaD [51]

Answer:

- Organism A is most likely a herbivore

- Organism B is most likey a carnivore

Explanation:

Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.

- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.

Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.

- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.
