Question

Geographical and reproductive isolation of organisms gradually leads to speciation

Answer 1

$\huge\pink{\mathcal{♡Answer:-}}$

It happens when a population is separated by mountains or land masses thus preventing crossbreed in between the two populations. This leads to barriers to gene flow hence evolution occurs and thus speciation takes place.

Answer 2

Answer:

• Evolution  leads to  the  formation  of  new  species  from as speciation.
• An  existing  one  is known Species  is the  group  of  organisms that  can  reproduce  among  themselves and  produce  fertile  offspring.
• The  origin  of  many  species  is due  to  the  separation  of some  individuals of  one  species by  geographic barrier.
• It  prevents  the  reproduction  in separated  groups.  
• The  separated  groups can  follow  its  own  evolutionary  course  and evolved  into  two  species.
