How do helpful variations accumulate in species over time?

Social Studies
1 answer:
Fiesta28 [93]3 years ago
5 0
I assume that the question here refers to the process of evolution. The "helpful variations" are small mutations that allow the organism to have a small advantage over other - and this organism can then pass this variation to its children better than other organisms, meaning that with time, more organisms will have it. This will accumulate over time and the percentage of organisms with this mutation will increase.

Reminisching about old times triggers episodic memory, a division of long-term memory. This is a memory that occurs due to the brain connections of neurons that make up the nervous system.

Episodic memory is one that allows us to remember situations experienced in our life, such as time, place, people, emotions, etc.

Endel Tuving was the forerunner in developing the concept of episodic memory, and according to him, episodic memory allows us a "mental journey through time".

Therefore, episodic memory allows us to generate learning based on past experiences, in addition to allowing us to recall with greater vividness an event with a lot of emotional significance.
