Biocultural Development of Development – Part 2


Hey all, Welcome to Geeksforjobs

Bio-cultural development of development

Protected distribution

There are certain geographical parts that have long been different from the rest of the world because they have unique flora and fauna.

Examples given:

In Australia, there are egg-laying mammals such as platypus and kanguros such as sac animals that do not occur anywhere else in the world. Evolutionists explain this restricted distribution in the following way. During the Mesozoic era, Australia was separated from the mainland of Asia. This was before the placental mammals developed. Placental mammals, being more adapted, abolished the monotrem and most of the marsuplice in the rest of the world. Australian mammals could not reach Australia due to lack of land routes. So, primitive mammals of Australia survived there. Static mammals have evolved and evolved in rather different forms such as terrestrial, semicircular, arched, fossil, aquatic types. This type of evolution was called Deviation development or adaptive radiation.

Life in the Ocean Islands

Animals and plants in marine islands meet those animals in the nearest mainland. But, they are still different. for example, In 1835 Charles Darwin discovered that animals in the Galápagos Islands Resembles animals in the South American mainland 960 km away. It appears as if animals migrate from the continent or float abroad and enter islands in remote areas. Sea islands are animals that can survive travel from the mainland. Frogs, toads, and land mammals were not found on the Galápagos Islands, although environmental conditions were favorable because they were not able to escape from saltwater.

As the environmental conditions on the islands were favorable for life, the animals thrived and modified to adapt to the conditions there. Thus, the long isolation made these animals somewhat different from ancestral forms. Thus grew. An attractive group of closely related passerine birds, known in the biological world as Darwin’s feathers found on the Garipagos Islands, mainly adaptations in the type of food available in body shape, feather color, and bill size As vary.

Extensive development or adaptation

Processes of development that produce the same ancestrally evacuated new species and adapt to newly invaded habitats and newly invaded habitats and adaptive radiation or divergence evolution to the means of life are known.

An example of dialectical development is shown by Finches of Darwin in the Galápagos Islands. These finals originated along different lines from a common ancestral stock to avoid competition. They adopted new habitats and means of living necessary in such habitats, showing varying variations in bill sizes, feather colors, and the like.
