hypothesis is the savanna hypothesis‚ which states that many important human adaptations arose on the African savanna or were influenced by the environmental pressure of an expanding dry savanna. According to this idea‚ upright walking proved to be a beneficial way of moving across an open landscape. Another version of this idea is that upright walking had the additional advantage of freeing the hands‚ which was advantageous for carrying items and making tools in the African savanna. Other habitat-specific

Identify a biome in which the plants are short and require little water and the animals are small. Then‚ write a one page description of this biome. A biome is a large ecosystem where plants‚ animals‚ insects‚ and people live in a certain type of climate. Therefore‚ desert where the plants are short and the animals are small because of a lack of water. There is one-fifth of the earth land’s surface is desert. Deserts can be found on every continent except Europe. The desert biome can be separated

period has five epochs: 1. Paleocene-also known as “early recent” lasted around 65 million years ago. Marked by demise of dinosaurs‚ as well as existence of pre-primates like femur. 2. Eocene-lasted 30-45 million years ago. It is marked by warm tropical climates‚ along with the appearance of the order of mammals and prosimian-like primates. Anthropoids appreared during this period. 3. Oligocene-lasted around 30 million

One of the fiercest aquatic carnivores to roam the Earth and as big as 15 to 17 meters long it lived from the Late Oligocene to Early Pleistocene Era where the Megalodon lived in cold waters as the ice sheets have started to very slowly form from the cold waters of the Arctic but the Megalodon lived worldwide. Although being on top of the food chain the Megalodon also had competition which was the Odontocenti which consisted of raptorial sperm whale and squalodontis which were also apex predators

I’m an penguin and I live in the polar ice biome. We are birds with black and white feathers. Unlike most birds we don’t fly. We spend about 75% of our time underwater‚ searching for food in the ocean. We are one of about 40 species of flightless birds. We are known for their white bellies and dark-colored backs and wings. Our body is designed for swimming‚ and includes tapering at both ends of the body for hydrodynamics‚ paddle-like wings

The earliest hypothesis put forth to explain this was the savanna hypothesis‚ which became discredited when the archaeological record of hominids showed sites previous to the time of savannas being the primary landscape feature

all threats to wildlife‚ whether they’re rich tropical forests‚ mangroves‚ swamps‚ coral reefs‚ or your own local grassland or woods. Most wild plants and animals are so closely adapted to their own particular habitat that they become rare or endangered if it is damaged or removed. Globally‚ the most worrying losses of habitat are the tropical rain forests‚ because these contain‚ by far‚ the largest number of species. Although large areas of tropical rain forests still survive‚ they are still being
