Hello everyone welcome to this Channel 😊. In this channel you will find complex biology concepts into crystal clear forms . Classes will be in both English and Bengali so that our Bengali medium students who found it difficult to read ncert will get the most benefits. In this channel you will find biology related all video lectures from class 9-12. The students who are preparing for competitive exams like Neet , AIIMS nursing, cuet etc as well who are preparing for board EXAM all will be benefited. If you find this channel helpful then make sure to subscribe 😊,like👍 and share 😊..... It will motivate me to make such videos 😌.......Love you all my dear students. Best wishes for you 🤞❤️❤️💕💕.

Founder's Effect I I Adaptive radiation/ divergent evolution class 12 biology
Hey everyone welcome to Biology World. In this I explained in detail about founder's Effect and adaptive radiation/divergent evolution and it's consequences in evolutionary history. The founder effect is a concept in evolutionary biology that explains how a new population can have limited genetic diversity due to being established by a small group of individuals from a larger populations .
---
"The founder effect occurs when a small group of individuals becomes isolated from a larger population, forming a new population. Since this group carries only a fraction of the genetic variation from the original population, their descendants inherit this limited genetic diversity.
For example, imagine a few birds from a mainland population are blown to a remote island by a storm. These birds become the 'founders' of a new population on the island. Over generations, the genetic traits of this small founding group can dominate, even if they were rare in the original population. This effect can lead to unique adaptations, but it also makes the population more vulnerable to diseases or environmental changes due to the lack of genetic diversity.
The founder effect is an important concept in understanding how new species evolve and how populations adapt-or fail to adapt-to their environments."
