Name two types of evidence used to support the theory of evolution. explain how scientist use each type of evidence to provide s
joja [24]

Answer:

There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera

Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.  

For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.  

It shows divergent evolution and supports that these organisms have evolved from a common ancestor.

Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.

For example:

  • The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
  • Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.

balu736 [363]

Answer:

indeterminate

Explanation:

The answer would be <u>an indeterminate number of generations.</u>

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

<em>Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.</em>
