How the Mammals evolved into the larger

In just 10 years, the young whale can grow up to 30 meters. Increase the size of the animal's body is listed as one of the fastest on earth. They suspect the size of offspring success is due to the birth of a child to grow up.

The weight ratio of the weight of the baby determines the evolution of the mammalian host. This ratio explains why most mammals grow very large, while the other remains small. Evolution researchers from the Monash University, Alistair Evans, began the study with the assumption that body size affects the physiology and anatomy of animals. Factors such as heart rate, amount of food needed, and how to move depends on the physical dimensions. "Body size is fundamental to living things," he said through a press release, on June 24, 2013.

Evans then studied the development of whale body size, elephants, primates, and mice from the time of the dinosaurs to the present setback. After the extinction of the dinosaurs about 65 million years ago, mammals undergo drastic changes in body size.

The study concluded that species with rapid child reaches adult size tends to evolve bigger. Rapid development cycle of the body is so vital in the development of animal body size, no matter how many children are produced. The most significant case study can be seen in whales. "The reason is the speed into adulthood. Within 10 years, the length of this animal reaches 30 meters," said Evans.

Of all types of mammals, the order of primates is experiencing the slowest increase body size. Some families are including this Order, such as tarsiers, lemurs, monkeys, and apes, nothing weighs more than 500 pounds. "The slow pace of making mature mammalian body size evolution is very slow," said Arizona State University biologist, Jordan Okie. *** [EKA | FROM VARIOUS SOURCES | ANTON WILLIAM | KORAN TEMPO 4271]
