Jean Baptiste Lamarck published his theory of evolution in 1809.

. It is not until the sixth edition of the Origin 1872 that Darwin gives extended consideration to the long neck as an adaptation for feeding but in response to criticisms by Mivart not to make a contrast with Lamarck. Lamarck believed that animals could inherit traits acquired by their parents. Long necks were thus selected for in every generation gradually lengthening the giraffes neck over evolutionary time.

According to this idea each giraffe stretched its neck over its lifetime to reach leaves on high branches. Communicating through nocturnal humming is a barrier to classroom. What feature of the environment enabled the development of long neck of the giraffe.

However scientists are unable to explain the origins of its long neck. Giraffe Evolution and Ancestors. Why is Lamarcks theory no longer supported.

This stretching of the neck was passed on to their offspring over generations until it reached its current length. The long neck acquired by the giraffe was passed on to its offspring. Ionainjoy Ionainjoy 06082020 Biology Middle School answered Describe Lamarcks idea about how organisms evolved.

Use the giraffes neck as an example. 1 See answer Ionainjoy is waiting for. How Giraffes Became Winners by a Neck.

How giraffes neck gets longer and longer using the theories of modern synthesis. The same could be seen in every offspring of the giraffes. The best example to prove this theory was the elongated neck possessed by giraffes.

Who is associated with the statement. He believed that traits changed or acquired over an individuals lifetime could be passed down to its offspring. The theory of the French naturalist Jean-Baptiste Lamarck is the concept of use and disuse.

A giraffe that was born with a short neck might gain a longer neck through a lifetime of straining for leaves in tall trees. In a well known but incorrect hypothesis Lamarck a scientist that had hypothesized his ideas before Darwin famously suggested that giraffes grew to have a large neck by stretching towards branches on trees. According to Lamarck the giraffe got its long neck because its ancestors stretched theirs to eat leaves that were just out of reach.

According to Lamarcks theory a given giraffe could over a lifetime of straining to reach high branches develop an elongated neck. Not directly of course. Giraffes that had acquired long necks would have offspring with long necks rather than the short necks their parents were born with.

How did Lamarcks theories of evolution explained the giraffes long necks. The hypothesis that giraffes have long neck due to the scarcity. Organisms will develop new body structures when needed.

That is a characteristic that is used very frequently by a living being gradually develops and strengthens until it meets the need of the species. Sorry the first sentence was awful What is wrong with Lamarcks theory. Giraffes have taught generations of students how evolution works.

It is to eat the leaves and vegetation from higher places that giraffes have acquired a very long neck. Branch thought of evolution- survival of the fittest natural selection Who is associated with the statement. By continually doing this they not only stretched their own necks to be longer but then passed the growth they received in life to their offspring.

In his theory Lamarck proposed that traits like the long neck of a giraffe evolved over time by use and disuse. The coming generation would make more advanced adaptations to sustain in the existing environment. A species will change over many generations when individuals with certain traits produce more.

The problems addressed are how incipient stages of adaptive structures can be selected for and why if a trait is adaptive why dont all species or. The offspring of this giraffe would not have to. According to Darwins theory giraffes that happened to have slightly longer necks and limbs would have a better chance of securing food and thus be able to have more offspring the select who.

The giraffe is the tallest of all living animals. How would Jean Baptiste Lamarck describe the evolution of long necks in giraffes compare this to how Darwin would describe the evolution of long necks in giraffes. Lamarck believed that the stretching elongated the giraffes neck which became a useful characteristic and was passed onto future generations.

Use the giraffes neck as an example. The classic example used to explain the concept of use and disuse is the elongated neck of the giraffe. How would Lamarck explain the long neck of a giraffe.

In your own word please describe in detail how Darwins explanation for the evolution of giraffes long neck differs from that of Lamarck. Lamarcks theory was that animals acquired traits that made them more fit throughout their lives tendencies toward perfection use and disuse Like a giraffe extending its neck to get the higher leaves. Describe how Darwin would explain why giraffes have long neck.

The second part of Lamarcks mechanism for evolution involved the inheritance of acquired traits.
