Yes, humans are still evolving and have not met the hardy-weinberg equilibrium. Although, I do believe our rate of evolution has been slowed down. The hardy-weinberg theorem states that allele frequencies will not chance if there is a large population, mating opportunities are equal, no mutations occur, no migration occurs, and no natural selection occurs.
We certainly do have a large population (exception to certain isolated tribes that have not been influenced). This has slowed evolution because chance effect of genetic is nullified.
It is arguable to say mating opportunities are not always equal; we have a hierarchy in society where the rich are clearly separated from the average and poor. We all have a tendency to mate with each other. Also, our ability to reason (which seperates us from all other species) has allowed us to make a much more in depth analysis into what behavioral and physical traits we are attracted to in our mates (does not strike me as much different then sexual dimorphism). This implies sexual selection, which is a form of natural selection.
Think of all the locations where mutations occur (during replication, transcription, and translation), it is very unreasonable to think that in the entire human population no type of mutation ever occurs. It also has been proven that a mutation occurs, in a large population, in one in every gamete. Therefore, microevolution is still occurring.
The human race is obviously always migrating to different countries, and therefore are under different environmental pressures. A problem however is that we have gotten extremely good at altering our environment to our standards rather then adapting. Furthermore, it has been proven that a gene on chromosome 12 in Africans has 21 different variations (this is one amongst many differences in allele frequencies between different races). Therefore, if a North American, who only has 3 variations, mates with an African, then the allele frequency has changed and again the hardy-weinberg conditions are not met.

What allele frequency in a population do not change or the population does not evolve?
In a population where allele frequencies do not change, it is said to be in Hardy-Weinberg equilibrium. This condition occurs when certain criteria are met: the population is large, mating is random, there are no mutations, no gene flow (migration), and no natural selection. Under these circumstances, the genetic variation remains stable over generations, indicating that the population is not evolving.
What do sexual reproduction mutation and crossing-over generate in a population?
Sexual reproduction, mutation, and crossing-over generate genetic diversity in a population. This diversity increases the chances of individuals adapting to changing environments and evolving over time.
When allelic frequencies remain unchanged a population is in genetic eqilibrium this statement expresses what?
This statement refers to the Hardy-Weinberg equilibrium principle, which states that in the absence of evolutionary forces, allele frequencies in a population will remain constant from generation to generation. This equilibrium condition can be used as a null hypothesis to assess whether a population is evolving.
What is true about the mindset in approaching COIN?
In approaching COIN (counter-insurgency), it is important to have a population-centric mindset that focuses on winning the support of the local population. This involves understanding the grievances of the population, providing security and essential services, and building trust with the local communities to undermine the insurgents' influence. Flexibility and adaptability are also key in adjusting tactics to the evolving dynamics of the conflict environment.
Is Earth evolving around the Sun?
Yes, Earth is continuously evolving around the Sun in an elliptical orbit. This movement is known as revolution and it takes approximately 365.25 days for Earth to complete one orbit around the Sun, resulting in a year.
Is population evolving in genetic equilibrium?
It is true.
When a population is evolving what can you be sure is happening?
It's Changing
What is it called when a population is not evolving?
Hardy-Weinberg equilibrium
When a population of organisms is evolving what can you be sure is happening?
It's changing
If the actual allele frequencies in a population do not match genotype frequencies predicted by the Hardy Weinberg equation what is the population?
The population is evolving.
When a population is not evolving what is it called?
When a population is not evolving, it is called being in genetic equilibrium. This means that the frequency of alleles in the population remains constant from generation to generation. Evolution requires changes in allele frequencies, so genetic equilibrium indicates no evolution is occurring.
What is tourism according to Robert McIntosh?
According to Robert McIntosh, tourism is " a huge, complex, and continuously evolving industry."
What is nature meaning and elements of accounting theory?
Accounting Theory is defined as the study of methodologies and financial accounting principles. The Accounting Theory is continuously-evolving and changing.
What happens when a population is not evolving?
When a population is not evolving, it means that the allele frequencies within the population are remaining stable over generations. This could occur if the population is experiencing no mutations, no gene flow, no genetic drift, no natural selection, and if mating is completely random. In essence, the population is in Hardy-Weinberg equilibrium.
That the human population is no longer evolving?
That isn't true, in fact, about every 1 minute, a baby is being born.
What hsa to change from generation to generation in an evolving population?
The frequency of the populations alleles. Their gene frequency must change to have evolution.
What level does ursaring evolve?
Ursaring doesn't evolve according to level because Ursaring is not capable of evolving.
