Lamarck's idea suggested they stretched their necks and passed the stretching down through generations. 2012-01-07 Giraffe (Giraffa camelopardalis), with their long neck and legs, are unique amongst mammals. How these features evolved is a matter of conjecture. The two leading ideas are the high browse and the sexual-selection hypotheses. While both explain many of the characteristics and the behaviour of giraffe, neither is fully supported by the available evidence. Darwin’s story of how the giraffe got its long neck is perhaps the most popular and widely-told story of evolution.

Giraffes evolution of long necks

Anyone who has seen this majestic creature in the wild, nibbling away at the top of an acacia tree, has to marvel at the wonder of evolution. The giraffe’s long neck is a perfect adaptation to the animal’s natural habitat. Clearly the giraffe evolved this uncommon and helpful trait in order to reach those nourishing leaves. At some point, I thought I remember hearing that giraffes did not evolve long necks to reach higher food resources, but instead longer, stronger necks gave some sort of mating advantage (male competition perhaps?). Giraffes probably used to have short necks. Over time, since the branches of trees or plants were out of their reach, they adapted to this by having a longer neck. Those with longer necks are able to reach the food and eat it that those with short necks could not.

Determinism.

and evolution consistently selected for longer necks until giraffes reached their modern height (as explained by Kot-tak, quoted above). Giraffes with shorter necks were less likely to get a good meal, while those with longer necks were more likely to obtain one. As a result, giraffes with longer necks thrived, while those with shorter necks were Since female giraffes don’t fight, says Simmons, their necks are long probably because they share so many genes with males. Unlike males, though, who add about 90 pounds to their necks after becoming sexually mature, the necks of females stop growing at sexual maturity.

The long neck of the giraffe is supported with extremely strong anchoring muscles which help the animal keep its head upright. As a result of the evolution of long necks, giraffes have had to make several adaptations to survive, including the development of a very powerful circulatory system which pushes blood from the heart to the brain.

Long neck, camel-like shape, leopard-like coloring and horn-like ossicones don't come out of nowhere: giraffes are naturally bizarre. What would happen if

The two forces that drove giraffes towards elongating their necks are simple. The need to eat and the need to breed. Sexual Selection.

From their ridiculously long necks to their handsome patterns of spots, there's really no mistaking a giraffe. This animal adapted as a towering browser in African savannas, though biologists don't know for certain why it looks the way it does.

The latest and rather surprising theory, which hasn’t been proposed before, is that the giraffe’s long necks are the result of sexual selection—to compete for females, male giraffes developed a long neck. In the savannahs of Africa, it is by necking that male giraffes combat to win females.

In terms of the giraffe example, Darwin’s theory of evolution through natural selection would suggest that a giraffe was born with a longer neck by random chance. Because this individual had a longer neck, it was able to reach food sources that other animals couldn’t. For years, there has been scant fossil evidence showing how the giraffe evolved to have such an admirably long neck. But now, the remains of a 7-million-year-old creature with a shorter neck Tweaking a few dozen key genes that regulate development gave giraffes their long necks. It’s a discovery that points to the subtle complexity behind this striking adaptation. Biologists now The authors say that the study also suggests that features such as the giraffe’s long neck and specialised cardiovascular system might have evolved simultaneously, as some of the genes identified The long neck of the giraffe is supported with extremely strong anchoring muscles which help the animal keep its head upright. As a result of the evolution of long necks, giraffes have had to make several adaptations to survive, including the development of a very powerful circulatory system which pushes blood from the heart to the brain.
