What is the process called when farmers breed only their best livestock?

Artificial selection is a form of breeding that involves human intervention. It is a technique used by farmers to achieve desirable traits for their animals. In order to produce the “perfect offspring”, the farmers selectively choose animals to breed by manipulating heredity.

What term did Charles Darwin use to describe the ability of an organism to survive and reproduce in its specific environment?

→Fitness, the ability of an individual oto survive and reproduce in its specific environment, occurs through ongoing adaptation. An example is an animal that survies through camouflage. An adaptation is any inherited characteristic that increases an organism’s chance of survival.

What is the process of producing more offspring than can possibly survive?

Overproduction. Occurs when a species produces more offspring than will survive to maturity.

What does James Hutton’s and Charles Lyell’s work suggest?

James Hutton’s and Charles Lyell’s work was important to Charles Darwin because these scientists suggested that the earth was old enough for evolution to have occured. a detailed record of evolution.

What are 4 examples of selective breeding?

Different varieties of plants and animals with desired characteristics can be developed by selective breeding. New varieties

  • cows that produce lots of milk.
  • chickens that produce large eggs.
  • wheat plants that produce lots of grain.

Can humans be selectively bred?

The deliberate exploitation of selective breeding to produce desired results has become very common in agriculture and experimental biology. Selective breeding can be unintentional, e.g., resulting from the process of human cultivation; and it may also produce unintended – desirable or undesirable – results.

Why is selective breeding bad?

Risks of selective breeding: reduced genetic variation can lead to attack by specific insects or disease, which could be extremely destructive. rare disease genes can be unknowingly selected as part of a positive trait, leading to problems with specific organisms, eg a high percentage of Dalmatian dogs are deaf.

What does natural selection acts directly on?

Natural selection acts on an organism’s phenotype, or observable features. Phenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries).

Which scientist formulated the theory of evolution through natural selection?

The theory of evolution is a shortened form of the term “theory of evolution by natural selection,” which was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.

What four factors affect Darwin’s evolution?

Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment’s limited supply of the resources that individuals need in order to

What is Lamarck’s theory?

Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime —such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
