Evolution: Origin of life, Darwin’s theory, adaptive radiation

The ancestors of cockroaches originated during the carboniferous period, around 300-500 million years ago, they lacked the internal ovipositors of modern roaches. They have special adaptations which are sucking  Mouthparts like other true bugs are considered to be much more generalised insects. They have chewing mouthparts and the most primitive of living Neopterin insects. Tropical […]

According to Darwin, living organisms adapt themselves to changing environments for the continuation of their survival. The main reason which initiates the process of evolution is the demand of exploitation of a niche but inability to do so because of some structure and physical or anatomical issues. The phenomenon of adaptive radiation was first described

Introduction Evolutionary theory holds that living creatures change their physical and anatomical structures over a lengthy period of time in order to make better adaptations to their changing environment. When organisms attempted to exploit a niche but were unable to do so because of their current body design or structural component, this marked the beginning

Adaptation refers to the process of adjusting behaviour, physiology, or structure to become more adapted to a given environment in biology and ecology. It may also be described as the condition attained by a biological population that is experiencing modifications or adjustments. It might also refer to a characteristic that helped the species adapt to
