Because the animal is adapted to its environment. :)

∙ 12y agoBecause only traits that are controlled by genes can be inherited and since all traits have a genetic basis that leads to morphological and behavioral variation they must be selected against the immediate environment. Evolution, the change in allele frequency over time in a population of organisms, especially adaptive evolutionary change, could not happen without hard genetic inheritance acted upon by natural selection.

What controls traits and inheritance?
On my Science homework was the question What controls Inherited Traits? After reading through my text book I discovered that Inherited traits are controlled by genes. So, the answer to the questtion is genes!
Explain how the inheritance of traits is controlled in organisms Use the term genes and alleles in you explanation?
The most dominant traits are the ones that control organisms genes.
What are some traits such as the color of your eyes and the shape of your nose are controlled by?
genes '
Why does natural selection not directly affect genes?
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
What is Gregor Mendel's concept of unit character?
Inherited traits controlled by factors(genes) which occur in pairs : ) machuff15
Is it that traits that are controlled by genes can be acted upon by natural selection?
Yes.
Why can only controlled traits by genes be acted upon by natural selection?
because there are alot of peters iin the world like obama
What role do alleles play in natural selection?
Genes are the medium by which inherited traits are passed on to offspring. It is inherited traits, and thus genes, that receive positive or negative selection.
Why can only traits controlled by genes be acted upon by natural selction?
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 are the traits of an organisms are controlled?
Traits are controlled by the genes of the parents.
What controls traits in organisms?
The traits of an organism are controlled by genes and environment. Genes
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.
Explanation of Natural and Artificial Selection?
Artificial selection is when humans select traits, such as color or taste and breed for those traits. Natural selection chooses the creatures that are best able to give birth to more offspring, carrying on their genes. The environment chooses.
Traits of an organism are controlled by its what?
Genes
What are traits of alleles are controlled by?
genes
Traits controlled by two or more genes are?
Hello there! Traits controlled by two or more genes are for example skin color and height.
What are ways in which natural selection operates on ploygenic traits?
Polygenic? Natural selection usually acts on the phenotype of polygenic traits as they are suites of genes acting in concert to form a trait. If you had a trait, such as height, in two variant brothers then the aggregate would need to be selected for as the genes working in concert, but not equally well, would render different heights in the brothers which would be then visible to natural selection.
