Which of these best describes how evolution through natural selection works? a, individuals make an effort to improve, and that improves the phenotypes of the next generation.
00:12
Individuals that develop mutations that are more likely to survive will pass those mutations to offspring.
00:19
Only the strongest individuals survive to reproduce, so each generation is improved.
00:24
While successful phenotypes are more likely to produce survival offspring, changing the population's genetic structure.
00:30
Between generations.
00:33
So the answer here is d.
00:35
So evolution by natural selection, it means that there is heritable variation in the population.
00:43
And those organisms that are more adapted, so they're more likely to survive and reproduce, are then more likely to pass this variation onto the next generation.
00:56
So organisms with better, adaptation to the environment have an increased chance of surviving and reducing and their offspring inherit the adaptations.
01:14
And that's how the population becomes more adapted to the environment over the generations.
01:20
So it's not a or b because in both of these it's talking about acquired adaptation.
01:27
Acquire traits...
