The questions can you ask, and then investigate, to help determine the evolutionary relationship among the trout species are about the evolutionary changes.
<h3>
What kind of evolution is processing?</h3>
The evolution of various organisms from a not unusual place ancester took place thru the mechanisms like gene duplication, gene amplification, and mutations. Accumulation of mutations gives insights at the phylogenetic evaluation of organisms.
- From the given data, it could be stated that rainbow trout and brown trout have a current not unusual place ancestor. The species are carefully associated, and feature different very lately in phrases of evolution.
- However, the not unusualplace ancestor for not unusualplace carp and the opposite carps had different lengthy before, sufficient to build up enough mutations and display substantial version withinside the genotype of the chosen region.

Answers
The explanations that provide support for continental drift theory are;
• Coal fields match up across continents
• Tropical plant fossils were found in Arctic areas
• Similar rock types are found across continents
• Evidence of glacier can be found in South Africa
Explanation
According to Alfred Lothar Wegener in his studies on the origin of continents and oceans, he outlines that the theory of continental drift can be supported by five evidences which are; the jigsaw fit of the continental alignment, geological fit, tectonic fit, glacial deposits and fossil evidence.
