Because populations evolve. If their was no hereditary transfer of traits by germ line genes then there would be no true selection. Acquired traits, such as a personal habit, are invisible to selection. Somatic mutations that could be beneficial are also invisible to selection. Selection only acts on what is, germ lines in individuals, transmissible to future generation and the gene pool.
What else can I help you with?
Is it that traits that are controlled by genes can be acted upon by natural selection?
Yes.
Why does only traits controlled by genes be acted upon natural selection?
Traits controlled by genes are subject to natural selection because they are heritable and can be passed on to offspring, allowing successful variations to increase in frequency over generations. Traits that are not controlled by genes, such as behavior or learned characteristics, are not directly influenced by genetic inheritance and therefore cannot be directly acted upon by natural selection.
Why can only controlled traits by genes be acted upon by natural selection?
because there are alot of peters iin the world like obama
Is it true that only traits that are learned can be acted upon in natural selection?
all i know is that its False
Why can only traits controlled by genes be natural selection?
dBecause the animal is adapted to its environment. :)
Why can only traits controlled by genes upon by natural selection?
I'm assuming you meant "Why can only traits controlled by genes be acted upon by natural selection?" Genes hold all of the information that makes up something physically and to some extent psychological and that is what is past down to the offspring. That means any traits acquired can not be past down for example knowing how to hold a pen is not something that is stored in genes it is stored in memory therefore it can not be genetically passed down. If one day I were to get into a battle with a swords master I would win the battle because the pen is mightier then the sword. That would save my life and allow me to pass on my genes, but even though it played a role in natural selection by allowing me to live instead of the sword master it is not stored in the genes and therefore is not genetically passed down to the offspring.

water acted as a natural barrier before Romes enemies built ships.
Who acted as advisors controlled public finances and handle foreign relation?
Senate
Suppose the climate in an area becomes much drier than it was before what kinds of variations in the areas plants might be acted on by natural selection?
without variation's, all the members of a species would have the same traits.
What level of organization is acted upon by natural selection?
The individual or his/her (assuming a sexed species) genes. Still a bit of a ' bone of contention in biology between these two levels; the gene and the individual. The only truly marginalized position as to ' target ' of selection is the group.
Why did the extensive deserts on all sides help ancient Egypt develop civilization?
The deserts acted as a natural protection from invaders.
