What is an example of Lamarck's theories about Evolution? Giraffes as a species evolved a longer and longer neck over time
Giraffes with longer necks can pass on this trait to their offspring, creating more
long neck giraffes over time
O Giraffes gan acquire a long neck in their lifetime from stretching for food, and
pass it down to their offspring
Natural variation in giraffes that allows some giraffes to be better adapted to the
environment and reproduce

i think this picture will you.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
