For those who don't know much about it, each gene determines certain physical characteristics and brain capacities of the individual. Practically each gene help create three proteins that the specific kind of body need to function properly. When the chromosomes change their normal arrangement, it is considered an anomaly that makes the specimen not a normal individual within the population.
If an ape ever changed its chromosome count, that was not an advance on its path to bringing its offspring closer to humans, but rather a backwardness, an abnormality that would surely have caused many problems in the survival of that individual and/or its offspring, which would be completely abnormal if survived, such as dwarfism, gigantism, Down syndrome and other genetic abnormalities. These changes were never and will never be favorable for the human species and its normal physical-intellectual development.
Imagine the effects that morphological and brain changes would have had on apes who were supposedly experiencing chromosomal abnormalities for millions of years...they say. That wouldn't turn an ape descendant into a human, but into some disabled ape. If we compare humans with apes, it is evident that we lack nothing because we have 23 pairs of chromosomes instead of the apes' 24 pairs, nor are they superior to us because they have a greater number.
There are about 3 proteins that each of the about 30,000 genes help create for our internal biological needs and anatomical configuration. Each chromosome has between hundreds and thousands of genes that carry out that immense internal work that very few know about.
Think about the fictitious event in which apes begin to lose genes that they need to remain biologically fit,... They have 48 chromosomes, while humans have 46, so there would be a loss of capabilities, not gains. Would defective apes become humans?
On the other hand, there is no real scenario where for millions of years apes are experiencing anomalies that would become the norm and would be favorable for entire populations of descendants.
Evolutionists are very fanciful. They have lost objectivity.
