Characteristics Of Darwin's Theory

Darwin’s theory caused a lot of controversy and his ideas were only gradually accepted, the reason for that is because Darwin’s theory was conflicted with religious views that God had made all the animals and plants on earth. He did not have enough evidence at the time to convince many scientists. It was 50 years after Darwin’s theory was published that the way that inheritance and variation worked was discovered, the genes that allow these individuals to be successful are passed to their offspring.

It is stated that Darwin’s theory is now widely accepted because it explains a wide range of observation, it has also been tested that and discussed by many

For example if a person eat too much he/she will become heavier and if a person eat too small/little he/she will become lighter, a plant in the shade of a big tree will grow taller as it tries to reach more light.

Example s of features that show environmental variation include language and religion, both types together their features vary because of a mixture of inherited causes, for example, identical twins inherit exactly the same features from their parents but if you take a pair of twins and twin “A” is given more to eat than twin “B”, twin “A” is likely to end up heavier.

Two forms of variation: Continuous variation

Characteristics showing continuous variation vary in a general way, with a broad range, and many intermediate values between the extremes. (www.biotopics.co.uk)

As a matter of fact if you consider a large enough sample from population perhaps plotting frequency as a histogram or as a frequency polygon, you will find that most of the values are close to the average and extreme values are actually rather rare.

High is an example of a continuous variable

Anthropologist Meave Leakey was responsible for naming the species in 1995.Known as Lucy fossil Australopithecus afarensis ranged through Ethiopia, Kenya and Tanzania from 3.85 to 2.95 million years ago. The species is thought to be either a direct ancestor of genus Homo or a close relative of such an ancestor. It is also the first species that made scientists realize that upright walking evolved before large brains.

It was discovered that afarensis walked on two legs but still had long arms for climbing trees. Its brain size was about a third of the human brain size, its teeth were larger than human teeth but smaller than ape teeth and it also had a protruding ape-like jaw. Afarensis matured at a faster rate than humans. Discovered in 1924, The Taug Child was the first evidence of early human species in Africa. The name Australopithecus Africanas literally means Southern ape. It was named for the fact that in lived in modern-day South Africa. It was the first of many hominid species to be discovered on the African
