a) Name the following:
     1) The forerunner of hominid evolution.
     2) The product formed in miller's experiment.
b) What are darwins finches? How do they illustrate adaptive radiation?

Dear student,

1.FAmily Hominidae has formed from the  Hylobatidae (Gibbon) family .
Hence Gibbons are forerunners of Hominid Evolution.

2.Miller created electric discharge in a closed flask containing Methane,Hydrogen,Ammonia and water vapour at 8000C.He observed formation of amino acids.

3.Darwin finches are small black birds.
From the original seed eating features,many other forms with altered beaks arose enabling them insectivorous and vegetarian finches.
The process of evolution of different species in a given geographically area starting from a point and literally radiating to other areas of geography is called Adaptive Radiation.
