Okay.
00:22
So there is a population which is showing the different wings type of the birds like these are longer every size wings then green one are longer size wings and the blue one are short size wings okay so the red one are actually average size wings birds green one are long size wings and the blue one are short size wings okay so there is suddenly a severe is happening in this place.
01:28
Due to the civil storm, there is reduction in the population and only average size wings per better survive while the long size wings and the short size wings are lesser.
01:47
Now, after certain time, there are only, after short period of time, there are only one type of wings are there, that is, long size wings birds.
02:10

02:11
And this green one, sorry, wait a second.
02:19
So, this green one and blue one are actually launched.
02:29
So in this place, where is long size wings birds, there is reduction in the genetic population.
02:35
Okay.
02:36
What is there? there is reduction in the genetic population...
