and tail undulations when they developed a shortened‚ more rigid body form during the Triassic‚ as an adaptation for armored resistance to attack by predators. However‚ terrestrial body form with a carapace and walking-type limbs precluded aquatic locomotion and was preadapted for different types of propulsion. In the transition to aquatic life‚ the shell underwent minimal modifications. These were a lower more streamlined profile and an expansion of the plastrel lobes as an adaptation for swimming

Modern taxonomy has rearranged the group formerly known as Kingdom Protista‚ separating the different types of organisms into their own candidate Kingdoms. Protists vary in how they obtain energy (autotrophic or heterotrophic) and in their locomotion. Locomotion Movement is achieved by several different methods in the protists.

He questions that if animals such as primates can demonstrate moral behaviors such as‚ reciprocation and empathy‚ then it is possible morality has a scientific explanation rather than a spiritual one that many religious individuals have said govern our decision making from deciding right from wrong.

Machiavellian Monkeys‚ James Shreeve‚ Discover‚ June 1991. Fraud. Deception. Infidelity. Theft. When these words are spoken‚ or read‚ the first thought is of human traits. Not once would someone think of animals as being capable of such actions‚ but people forget that humans are animals‚ and that the human animal evolved from a creature

Natural selection forms the foundation of how we understand the ways that species have formed over time. Another form of selection is sexual selection‚ which is the selection of traits based on their roles in courting and mating. It involves attracting a mate with the greatest fitness while simultaneously portraying oneself as the best mate for selection. Fitness‚ described in natural selection‚ is the ability to reproduce and leave successful offspring that will continue the cycle. Sexual selection

"Humans are Old World primates" Humans however have striking similarities as well as differences from that of the chimp or gorilla. For instance vision human vision is the same as any other diurnal primate meaning we clearly see the same as monkeys and apes. Our sense of smell is the same as that of the anthropoid primate or ape. Similarly our behavior patterns are closely resembled of most old world apes‚ humans live in

The objective of our experiment was to determine the effect of temperature on the rate of movement of Porcellio scaber. Our prediction was that P. scaber would have faster rates of movement in hotter temperatures. We expected this response as P. scaber is an ectotherm. Hence‚ its body temperature is directly determined by the temperature of its environment (Mellanby 1939). Løkke and van Gestel (1998) stated that the rate of the metabolism is controlled by the environmental temperature for ectotherms
