This requires further adaptive processes for immediate survival which, in themselves, may compromise post-natal survival, or be insufficient, with fetal demise occurring during birth. Following delivery, the lungs must be expanded and functional, changes must be made to the circulation, body ...
Water makes a good shelter for many animals. When the weather gets cold, they move to the bottom of lakes and ponds. There, frogs, turtles and many fish hide under rocks, logs or fallen leaves. They may even bury themselves in the mud. They become dormant. Cold water holds more oxygen...

There are still millions of animals that no one has seen. Many ofthem are in the treetops.23. What do scientists go to the treetops for?A. To build walkways there.B. To learn about the rainforest.C. To studying living things there.D. To look at the things far away.24. Why is ...
form of selection arising from the social environment. The perception of social isolation has profound phenotypic and fitness consequences in animals – not always negative81, even in insect taxa not typically considered to be social, and intriguingly, often with effects on immunocompetence82,83,84....
Bergmann and Allen first predicted latitudinal clines in animal size and shape based on thermal adaptation to different climates (‘thermoregulatory hypothesis’4,5,19). In cold climates, larger body sizes and shorter appendages reduce the surface area available for heat loss, allowing animals to co...
Sexual reproduction itself is a product of natural selection — organisms that blend genes in this way gain access to a greater variety of traits, making them more likely to find the right traits for survival. What's a Population? A population is a defined group of organisms. In terms of ...
2 Physical adaptation to exercise can lead to improved health. 2 Environmental adaptation is key to the survival of wildlife. 1 Adaptation strategies are vital for businesses in a changing economy. Artists often go through a process of adaptation when developing their style.Common...
