No, humans haven't stopped evolving.

<h3>Why is it not possible to stop evolving?</h3>

Extinction is the sole method that may effectively halt the evolution of any living being. Reducing and maintaining population size to a limited number of people can delay evolution. By reducing the introduction of new mutations into the population, this will reduce the amount of genetic variation that is lost through genetic drift. A population's capacity to evolve can be significantly reduced, but not entirely eliminated, by sustained limited population size because genetic variety is the foundation of all evolutionary change. But with humans, there is no doubt that this is not the case.

Since our population has been growing over the past 10,000 years, the contemporary human gene pool today holds a vast store of genetic diversity. Consequently, our capacity for evolution has never been greater. Indeed, instances of recent, positive selection created, not lessened by cultural change, have made use of this genetic variety. The distribution of genetic variation within and among local populations is fast changing, which is driving a significant evolutionary change in the human species. This transition is further fueled by a fundamental shift in the equilibrium between genetic drift and gene flow.

Even if our cultural innovations do decrease selection on a characteristic, that trait may nevertheless evolve in correlation with the evolution of another trait, frequently in a non-adaptive manner and occasionally in a moderately maladaptive manner. Humans will continue to evolve as long as there is a reproducing population.

How is the study of life span human development related to life expectancy?
cupoosta [38]

Life expectancy provides a framework for timing about stages and periods of life.

<h3>What does "life span" mean?</h3>
  • life span: the amount of time elapsed between an organism's conception and eventual demise.

<h3>The definition of life expectancy:</h3>
  • The average number of years a person who reaches a certain age might expect to live is their life expectancy.
  • Estimates of life expectancy from the National Center for Health Statistics offer a trustworthy overview of mortality and population health in the United States.

<h3>Why is this crucial?</h3>
  • A common metric for assessing a community's general health is life expectancy.
  • Age-specific health is measured by life expectancy at birth.
  • Trends in mortality are frequently described in terms of changes in life expectancy.

(6)A population begins at 42 individuals,climbs to 122 individuals and then levels off. This trend best illustrates which of the
N76 [4]

The answer is B.

This is because it says that the population tends to level off meaning that it stays around the same population size since it is the maximum amount of individuals that can survive.
