Line 34:
Penguins employ physiological adaptations and cooperative behaviors to deal with an incredibly harsh environment, where wind chills can reach -76°F. They huddle together to escape wind and conserve warmth. Individuals take turns moving to the group's protected and relatively toasty interior. Behavioral adaptations are the things organisms do to survive. Huddles allow them to share body warmth, and shelters many of the penguins from the wind. The huddle constantly moves so that all the penguins have a turn in the middle. Huddling can reduce heat loss by up to 50%.

Little Blues are temperate water penguins that can be found both on the mainland and offshore, preferring locations with rocky shorelines. Adults can be almost black, slate-blue, or indigo-blue on their heads and upper bodies. The penguins' color varies depending on where they live. From the chin to the belly, small, slate-grey feathers cover the ears before turning white below. Blue covers the flippers. The bill is a dark grey-black color and is 3-4 cm (1.2-1.6 in) long. The feet are pink above with black soles and webbing, and the eyes are pale silvery, bluish-grey, or hazel. The upper parts of juvenile birds are lighter and have a shorter bill. Black down covers hatchlings for eight to fourteen days before being replaced by chocolate brown down. Between 26 and 29 days, feathers take the place of down.
Penguins have the most devoted parents. Little Blue penguins incubate the eggs for almost 65 days in his brood pouch. Little Blue Penguin father incubate the eggs for almost 20 to 24 hours a day while sleeping. Embryos of these penguins are also poikilotherms that means their temperature are regulated by the external environment. Limiting factor are resources or other factors in the environment that can lower the population growth rate. Limiting factor include a low food supply and lack of space. Limiting factor can lower birth rates, increase death rates, or lead to emigration.

Males stand and protect their eggs from the elements by balancing them on their feet and covering them with a feathery skin known as a brood pouch. During this two-month guarding period, the males eat nothing and are at the mercy of the Antarctic elements. Male emperors keep the newly laid eggs warm, but do not sit on them as many other birds do. Males stand and protect their eggs from the elements by balancing them on their feet and covering them with a feathery skin known as a brood pouch. During this two-month guarding bout, the males eat nothing and are at the mercy of the Antarctic elements. Altruism is the principle and moral practice of concern for the welfare and/or happiness of other human beings or animals, resulting in a quality of life both material and spiritual.
Penguins can lose heat through many means to help maintain thermoregulation and homeostasis. Penguins can vigorously ruffle their feathers, which break apart insulation layers allowing heat to escape. Insulation and vascular heat-retention mechanisms allow penguins to forage for a prolonged time in water that is much cooler than core body temperature. Wing-based heat retention involves a plexus of humeral arteries and veins, which redirect heat to the body core rather than to the wing periphery.
==General
Evolutionary logic basically involves the principles of adaptation and natural selection. The evolution logic basically involves the science and principles which helps in understanding how evolution took place through different steps. It helps in providing arguments and rationale for understanding the evolution. Yes, evolutionary logic makes sense because it has been proved based on some research that evolution takes place due to adaptability and how an organism tend to adapt based on the changing environmental conditions. It makes sense because it involves number of behavioral pattern and how an organism tend to adapt based on the natural selection. The organisms which have better reproduction capacity and superior genes are naturally selected and weaker ones do not go forward.
