Birds Evolution Essay, Research Paper

Every being at one clip or another has to larn to accommodate to a new

environment. This is why development of being is needed in order to last

alterations to its environment, such as the instance of the flightless birds. For one

ground or another over a period of 100,000 old ages the demand for wings was

unneeded to their endurance. There could be many grounds why the birds evolved

to be more adaptable to their environment. A little population of birds would

hold to refill and get down a new population. In all populations there are great

generative potency to replace Numberss and expand the figure of population.

After their population grew there would be a grading off of the population one time

it reached a stable size. The birds & # 8217 ; population would go stable due a deficiency

of nutrient to back up every bird in the population, along with marauders helped to

contribute to maintaining the population stalls. After being on the island a

while

the birds & # 8217 ; population would get down demoing a fluctuation in different traits. Such

things as colour, flying size and overall size may change, due to marauders and the

terrain of the environment. Finally the birds evolved to the point where the

usage of their wings was no longer needed, as a necessity to last. The

version could hold been because winging itself took to much energy, so to

preserve nutrient they didn & # 8217 ; t wing excessively much. The bird & # 8217 ; s nutrient besides could hold been

near to the land and there was no demand to truly wing. Another thing could

have been that it was difficult for marauders to catch the birds if they stayed in

think under coppice or traveled along the land. For whatever ground the birds

didn & # 8217 ; t need their wings this trait was passed of from coevals to coevals.

The ground this trait was passed on was because it helped the endurance of these

single birds. They were able to reproduce and go through these traits through

heredity.
