The fossils of a new species of reptile are found in deposits dating to the permian period. later, scients discover that fossils of the speces changed somewhat over time and can be found in deposits dating from the permitan period all the way up to the cretaceous period. the fossils vary from one continent to another, but many seemingly intermediate forms are found, and the fossils are spread over most continents. the scientists' observations most strongly support which evolutionary models?
a. ellopete speciation
b. punctuated ovolution
c. adaptive radiation

The correct answer is option c. "adaptive radiation".

Explanation:

The term "adaptive radiation" is used in evolutionary biology to describe a evolutionary history at which many different organisms are created as a result of a rapid diversification of an ancestral species. This phenomenon takes place as a result of changes in the environmental conditions that forces new species to adapt quickly. The scientist observations of many intermediate forms at different continents of an ancestral reptile, most strongly support the evolutionary model of adaptive radiation.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
