Ursus arctos., Kodiak Bear is the largest of all the brown bears of the Alaskan coast and islands, which weight up to 680 kilogram. Also called Big Brown. These giants fatten on everything from mountain blueberries to washed-up whale carcasses, but their particular prey is the big Pacific Salmon.Few Kodiak bears have been weighed in the wild, so some of the weights are estimates. Size range for females is from 225 kg (500 lbs) to 315 kg (700 lbs) and for males 360 kg (800 lbs) to 635 kg (1400 lbs). Mature males average 480–533 kg (1,058–1,175 lb) over the course of the year and can weigh up to 680 kg (1500 lbs) at peak times. Females are typically about 20% smaller and 30% lighter than males and adult sizes are attained when bears are 6 years old.

Australopithecus africanus., designated STS 5, was discovered by Robert Broom and John T. Robinson in Sterkfontein, Transvaal, South Africa in 1947. Although originally considered female, study of the roots of the canine teeth has cast serious doubt on it's gender, leading most to believe it is,in fact, from a sub-adult male instead.

Austrolopithecus afarensis., Lucy is, quite possibly, the most well-known fossil hominid. Discovered by Donald Johanson and Tom Gray in 1974 at Hadar, Ethiopia, Lucy is dated at 3.2 million years old. This specimen, a 40% complete skeleton of an adult female, gave sufficient evidence that A. afarensis was a bipedal species that walked upright. Lucy, scientifically known as AL 288-1, was named after the Beatles song "Lucy in the Sky with Diamonds."

KNM ER 1470 Skull - First discovered in Koobi Fora, Kenya is 1972, Homo rudolphensis has consistently been the subject for debate. Many anthropologists believe this specimen to belong to the Australopithecine genus while some favor Homo habilis as its species. There are many features used to distinguish this sole specimen (KNM ER 1470) from both of these groups, but a consensus has yet to be reached.
