Fossil evidence of eukaryotes dates back to
a. 2.5 BYA.
b. 1.5 BYA.
c. 2.5 MYA.
d. 1.5 MYA.
Introduction:
The fossils of eukaryotes were found around
Answer to Problem 1U
Correct answer:
The fossils of early eukaryotic organisms emerged
Explanation of Solution
Reason for the correct statement:
The fossil record indicates the emergence and origin of the eukaryotes with the presence of true nuclei
Option b. is given as “
As, fossil records of the eukaryotic organisms dates back to “
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as “
Some species of bacteria evolved
Option c. is given as “
Some species of humans evolved
Option d. is given as “
Some species of humans like Homo habilis evolved
Hence, options a., c., and d. are incorrect.
The fossil record indicates the emergence of eukaryotes around
