Sir, please elaborate this paragraph especially last lines.".. bits and pieces........".
jOined and have since moved apart. The creation of Gondwana Gondwana's final formation occurred about 500 million years ago, during the late Ediacaran Period. By this time, multicellular organisms had evolved, but they were primitive: The few fossils left from this period reveal segmented worms, frond-like organisms and round creatures shaped like modern jellyfish. In this world, Gondwana conducted its slow grind to supercontinent-status. Bits and pieces of the future supercontinent collided over millennia, bringing together what are now Africa, India, Madagascar, Australia and Antarctica. This aarlv version of Gondwana joined with the other landmasses on Earth to form the single aanlkon ia 220 milion vears ago,

means before million years ago when gondwana supercontinent formed it has to collect all the land masses of Africa, Australia,madgascar ,America,anatrctica . which are now all separated.

but i was thinking, pangea itself a whole great landmass, which further spits into Laurasia and Gondwanaland. then how gondwana collects land masses of Africa, Australia etc. as u said. sir.
![eduncle-logo-app]()
pangea is made up of gondwanaland and laurasia
![eduncle-logo-app]()
see this when you study higher you will know about the supercontinent cycles
![eduncle-logo-app]()
{Gondwanaland and( laurentia+ baltica)=lauresia } = Pangea
![eduncle-logo-app]()
then pangea break apart

Multicellular organisms were evolved by the end of formation of Gondwana. As small continents collapsed with Gondwana, it became a supercontinent. Organisms thrived on this supercontinent and with time as a result of plate tectonic activities, countries like India, Madagascar etc. got separated from that supercontinent. We find the evidence of Gondwana supercontinent by similarity in fossils etc.
