How did the artificial selection practiced by pigeon breeders influence darwin's theory of evolution by natural selection?

a.
darwin concluded that if artificial selection could change a population over time, it could change a population instantly as well.
b.
darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature.
c.
darwin concluded that if breeders could select for certain traits in pigeons, they could also select for certain traits in saddleback tortoises.
d.
darwin concluded that if pigeons could choose their own traits, then animals in the wild could also choose their own traits.

Option B, Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature.

Explanation:

Darwin from the study on pigeon concluded that if certain traits with in the pigeons could be transferred/passed on from one generation to another through artificial or selective crossing then the same thing can be achieved through natural selection but the time required for getting the desired results through natural selection would be high.

In other way if artificial selection causes the passing of certain trait in a given population in an instant time period then the same traits can be passed on through natural selection process over a long time period.

Hence, option B is correct.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of amino acids , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in genes . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called transcription ), and the mrna is transported to the ribosome . protein synthesis, also called translation , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the nucleotides of mrna three by three, in units called codons , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the amino acid chain goes on to be processed and folded to make the final, functional protein

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
