Question

question: darwin concluded that any new species is closely related to the extinct species, but that small changes over time are what lead to the new species. which of the following helped him conclude this? answer options: select one of four fossil records zoogeography serology homologous organs

Explanation:

Fossil records show the existence of extinct species and the gradual changes in organisms over time, which supports Darwin's conclusion about new species being related to extinct ones and evolving through small changes. Zoogeography deals with animal distribution, serology with blood/immune systems, and homologous organs show common ancestry but not the link to extinct species over time as directly as fossil records.

Answer:

A. Fossil records
