Environment IS natural selection, so a change in environment is a change in selection pressure.
A change in the physical environment - a change in temperature or pressure
The environment was different in the past and will change again in the future.
Yes. Evolution via punctuated equilibrium still depends on natural selection. In punctuated equilibrium there are long periods in which most species are well-suited to their environments, and so there is is little selective pressure to change. These periods are punctuated by times of more rapid environmental change and greater stress, which results in greater selective pressure for populations to change.
The need for a change itself. For example, the need to migrate in order to keep up with food sources would bring an organism into another territory that their bodies might not be adjusted to. Rather than dying off, the "fittest" organism of that breed might mate with another "fit" organism, and after - guessing - 20 generations or so, genetic changes will have made that territory the most suitable environment for that organism.
Pressure for stability originates within the organization
Following are some barriers that might cause hindrance to the critical thinking process:ego-centrism (self-centered thinking)sociocentrism or ethnocentrism (group/society/cultural-centered thinking)fear of change or an unwillingness to changeprejudiceselective perception and selective memorypeer pressure
The chemical change is made by these following:- 1. Temperature 2. pressure 3. Nature of chemical
Metamorphism is a PROCESS. metamorphism is the process of change that occurs to rocks when they are subject to heat, pressure or both.
a tsunami effects the environment by change
They change their alleles ( different molecular forms of the same gene ) over time due to naturally selective forces, among others, to shape their morphology and behavior into new adaptions in the ever changing environment by just responding to the immediate environment.
