An examination of the fossil evidence indicates that, over time, giraffes have become taller, with longer?

Question

legs and necks. Explain this evidence using the Theory of Evolution by Acquired Characteristics or using the Theory of Evolution by Natural Selection

Answer 1

Explain this evidence using the
Theory of Evolution by Acquired Characteristics
an animal that "wanted" leaves from taller trees influenced the grown of its own body to be taller and this somehow (undefined) passed throughout the whole body, including the eggs and sperm and produced taller kiddos. Not a good explanation.
or using the
Theory of Evolution by Natural Selection
some of the animals were born with longer necks and legs and could reach food that other animals could not, so were healthier and had more and healthier kiddos who on average inherited the genetic disposition for longer necks and legs.

Answer 2

Acquired characteristics means strecting to reach high leaves made a longer neck and legs.

Natural selection implies for whatever reasons, height was a favorable trait (range of vision, access to new food, etc.) that overcame the numerous disadvantages. At first, there was variation in the population with the longest legs and necks were selected. Certain limits were reached, and novel mutations (neck valves) allowed new limits. This is a combination of gradual changes by selection of variations and leaps due to novel adaptations.

Answer 3

obtained features frame of mind strecting to attain severe leaves made an prolonged neck and legs. popular determination implies for some problem motives, top became a superb trait (style of inventive and prescient, get entry to to new foodstuff, etc.) that overcame the infinite hazards. to commence with, there became version interior the inhabitants with the longest legs and necks were chosen. particular limits were reached, and novel mutations (neck valves) allowed new limits. this is a mixture of sluggish differences through determination of adjustments and leaps therefore of novel adjustments.
